BRAKE SERVICE

Servicing Brakes: I’ve Finally Found My Match! B

rakes are undoubtedly the largest volume repair in most independent repair shops today. When performed correctly, they can be a very profitable service. Depending on how the vehicle is driven, proper brake repairs should last anywhere from 40,000 to 60,000-plus miles, with some exceptions of course, such as taxi cabs and mail delivery vehicles, etc. Pads and rotors are the foundation of any ABS, stability or traction control system. Without the right friction levels or rotor surface, these complex systems will not operate properly. This is why extra attention should be paid to any late-model vehicle when performing basic brake repairs. As vehicle weight became a great concern due to increased fuel mileage, manufacturers began designing brake components lighter and with the composite rotors cast with two alloys. These lighter components on today’s modern vehicles tend not to absorb vibrations as well. These new designs are even more prone to stacked tolerances in the knuckle-to-bearing and the hub-to-rotor assemblies. Rust and corrosion have increased the chances of lateral run-out and thickness variations as well. Lateral brake run-out means the rotor wobbles from side to side when spinning. Lateral run-out will cause the rotor to contact the brake pads, knocking them back as the high spot of the run-out

contacts the pads, allowing more pedal travel before the pad’s surface makes contact with the rotor. Rotor run-out will lead to thickness variations, inevitably leading to brake pulsations. Rotor and hub run-out must be less than 0.002” to minimize lateral run-out and thickness variation. In comparison, a normal piece of copy paper is 0.004” thick, so you can see that there’s not much room for error. Whether reusing the existing or replacing with new rotors, they must be matched to the hub due to runout variations between the hub and rotor utilizing an on-vehicle brake lathe, see Figure 1. Not performing the correct procedures can cause brake pulsations, inevitably leading to dissatisfied customers and comebacks. Rotors need to be serviced during every brake pad replacement and, depending on geographical location (especially the Rust Belt), the rotors

need to be serviced due to rust alone. In the past, a technician would remove the rotors and replace them or resurface them to help correct lateral run-out, parallelism, tapering, dishing, etc. on a bench lathe and then reassemble them back on the vehicle. Bench lathes can be of some concern due to conditions mentioned previously (hub-to-rotor variations). Resurfacing on a bench

lathe true’s the rotor to the lathe, not to the vehicle or hub. Prior to using existing rotors, a micrometer should be used to check for thickness to ensure the rotor is worthy of being resurfaced. If the rotor thickness is acceptable, a dial indicator should be used to check for lateral runout, dishing or taper, see Figure 2. Advanced on-vehicle brake lathes have the ability to measure rotor thickness electronically on a digital read out, and also measure the amount of cutting depth adjustments made digitally. So, the questions remain to be asked: are the existing rotors reusable or will they need to be replaced? Several things need to be observed when deciding to reuse the existing rotors. First, is

the rotor worthy of being resurfaced? We’ve probably all seen the split vented rotor, see Figure 3 on page 8, this is due to extremely rusted cooling fins. The fins hold the inside of the rotor to the face. Discard the rotor if you find thinning cooling fins or extreme rust buildup. For non-vented as well as vented rotors, check to see if they have been overheated. This can cause small or large cracks, Fig. 2

BRAKE SERVICE have been overheated. This can cause small or large cracks, causing lateral run-out and will deem the rotor unusable, see Figure 4. Specifications provided from the manufacturer typically give a disc diameter, maximum lateral run-out, parallelism, allowable scoring, etc. Important: Keep in mind to discard the rotors if they are below minimum refinish thickness or discard thickness to prevent an unsafe brake system. When reusing the existing rotors, we obviously know to resurface them, as pad slapping Fig. 3 is a thing of the past, as I truly hope! On-vehicle brake lathes are required by most vehicle manufacturers when performing brake repairs. Always check manufacturers’ specification when servicing vehicles. Similar conditions exist when installing new rotors on the vehicle, such as hub-to-rotor matching. When rotors are manufactured, they are trued to a lathe, not the vehicle hub. Adding to that, another issue can be shipping and storing rotors that can affect lateral run-out. Rotor costs vary depending upon rotor quality, manufacturer, vehicle and supplier, as well as the material used to design the rotor. A parts supplier may give you two prices, one for its average store line and another for a premium rotor. For example, 2006 Impala rotors from one part supplier had two rotors available, the premium rotor was twice the price of the store line rotor. While the premium rotor may cool better and not rust as quickly from “lot rot,” this does not alleviate the need to true or match it to the hub. Hub-to-rotor matching is a necessity to ensure a quality brake repair, and purchasing the highest quality rotor won’t eliminate this concern. In other words, even though two vehicles are the same year, make and model, they may have completely different stacked

tolerances and lateral run-out with the same rotor. In some cases, just removing the wheels can disturb rust between the rotor and hub. Prior to matching rotors, whether reusing or replacing them, clean the hub and rotor surfaces. Rust and corrosion can build up on the surfaces between the hub and rotor. Removing the wheel can loosen corrosion, constantly changing contact areas. Cleaning the corrosion from the wheel, rotor and hub is also important to prevent “wheel offs.” Once the wheel/rotor is loosened or

BRAKE SERVICE removed, the corrosion loosens, and, if not removed, the wheel may appear as if it has been correctly torqued, however, once the vehicle is driven, the corrosion shifts, loosening the wheel. Most “wheel offs” have been related to corrosion on surfaces of the hub, rotor and wheels, especially with aluminum wheels. Figure 5 on page 8 shows an aluminum wheel partially cleaned. If it were to be installed without a thorough cleaning, it would most likely cause damage. Clean surfaces also provide proper heat transfer from the brake components, allowing proper cooling. Using a good stainless-steel wire brush makes a big difference. I have found “caliper brushes” work well for this, and they are thin enough to get between the studs and hub center, see Figure 6 on page 8. There are also the surface cleaning discs made to go over the studs to help remove corrosion, see Figure 7. Resurfacing the rotors on the vehicle is a must when reusing or replacing rotors, see Figure 8. Typically, a pulsation is not going to be felt by the technician when burnishing the brakes or a simple road test. Also, pulsations will increase over time and are most often felt on high-speed slowdowns or stops, such as highway off ramps. Pulsations can take some time for the vehicle occupants to feel and they may continue to drive the vehicle for months after, increasing the pulsation until it is unbearable. The customer now returns with a brake pulsation concern or worse — they don’t return to your shop at all. They may have the vehicle repaired elsewhere, not giving you the opportunity to correct the concern. So, eliminating any chance of a pulsation or noise concern the first time will increase customer satisfaction. In Figure 9, one 0.008” cut was made (0.004” per

Fig. 8

side) on a new installed rotor; you can see that 25% of the rotor was missed with the first pass of the lathe. This new rotor was matched to the vehicle hub to run a true centerline and help eliminate any brake pulsations. Just think if this were not matched to the hub. How would the brakes wear, would the pedal feel smooth? Now, I know what you’re thinking, how is this going to improve my brake repairs? I haven’t had many issues. I thought the same thing until I began matching rotors to the hub. Instantly, while road-testing the first vehicle, it seemed as if braking was effortless and smoother than I ever felt when applying Fig. 7 the pedal. Once you try this, I’m sure you’ll agree and so will your customers. After resurfacing the rotors, be sure to wash with warm, soapy water to prevent brake noise. I know it’s an extra step and brake clean works just as well — so you think! Try this: resurface a rotor, blast it with brake clean and wipe with a clean paper towel, repeat again and one more time. You continue to remove particles of metal from the rotor. Now try this with soapy water and you’ll understand why it’s necessary to avoid using brake clean for this procedure. Using soapy water in a spray bottle and rinsing it off works very well. Using on-vehicle brake lathes for today’s vehicles is a must whether you’re reusing or replacing the rotors. As vehicle operators drive faster (speed limits...who obeys them?!) and vehicles are equipped with lighterweight components, vibrations increase from the smallest amount of lateral run-out. Taking several extra steps will help prevent brake repair comebacks, assuring customers are satisfied when braking for thousands of miles. TS

everely worn brushes and/or commutators can show as intermittent glitches in the waveform. See Figure 1. Note that fuel pumps can be equipped with an axial or a radial commutator. The radial commutator design tends to show a “dirtier” waveform. The waveform in Figure 2 shows loss of mechanical connection between the electrical motor and the impeller. If the intake strainer (sometimes called a sock) is plugged, the fuel pump impeller may start to cavitate where the fuel is literally evaporating at the impeller. The low pressure caused by the plugged intake is adding to the low pressure behind the impeller vanes, causing the fuel to “boil.” See Figure 3. The fuel pump may stall or have stalled. This could be caused by debris in the fuel tank such as rust particles, or a failure of the pump itself, such as the impeller breaking apart. A current waveform will clearly show this issue (Figure 4). The steadystate current consumption of a stalled pump will be very similar to that seen as inrush current when an operational fuel pump starts up. The current will be

Because they are so sensitive and easily affected, they need to be calibrated or zeroed before use. This is usually accomplished by pressing a button or turning a dial until the display reads close to zero. The calibration should be done with the probe held close to where it is to be used and oriented in the same direction as its intended use. Amp clamps can be equipped with a display, or with output jacks. If the probe is equipped with output jacks, the output is usually standardized to, for example, 1 mV per A. This is usually shown as 1mV/A. Other values such as 10mV/A or even 100mV/A can be seen as well. As a general rule, a more sensitive probe will have a larger mV/A value. Although most amp clamps have zero voltage output for no current flow through the wire they are clamped to, and must be zeroed before use, there are some exceptions. The amp clamp shown in

This particular probe has no zero adjustment and is primarily meant for oscilloscope usage. It can be used with a DMM, but some calculations will be necessary to arrive at the correct current values. This particular probe has 500mV/A or 100mV/A as settings — an output voltage of 2.6V would mean one A of positive current flow and 2.4V would mean one A in the opposite direction. As can be seen in Figure 7, this particular probe has very good resolution and the pintle opening “hump” can be clearly seen.

We will address this in a two-part series from the viewpoint of moments in time to offer a deeper understanding of these concepts. Our first article on this subject will address ignition-related misfires. We will explore other misfire research in the next article. The first step is to visualize these failures from the beginning — picture that an ignition-related misfire has occurred on a subject vehicle. We come to define it as a single cylinder misfire, prior to failure the pre-oxygen is switching and working as designed. The post-oxygen sensor is also working as designed and almost appears as a straight line when looked at per graphical data or a

PULLING CODES fuel trim (LTFT) will work to get the short-term numbers back as close as possible to at or near zero. The end result is that after corrective action has taken place by the processor, there will not be a significant impact on the total fuel trim (ST + LT). This analysis is based on a subject vehicle that has good fuel trim values to start with. A range of +/-5% is optimal on many systems today, but a range of +/-10% may be acceptable. A great example is a vehicle that has a total correction of 15% prior to fault; you’ll have higher numbers once ignition misfire activity occurs. I’ve found that on many vehicles with ignition misfire activity after the corrective action has taken place, single-digit numbers appear to be reasonable.

The Torch Wear Utility II Welding Coat weighs less than 2 lbs., provides a Thermal Performance Value (ATPV) of 12 cal/cm2, and is machine-washable in cold water. It repels sparks, spatters, molten metals and is abrasion-resistant to provide superior personal comfort. Unlike traditional welding coats, the Utility II coat does not require dry cleaning. Its innovative protective fabric treatment is bonded to the fibers and cannot be washed out. Because it is washable, the coat can easily be cleaned to remove grease or oil, helping to reduce the potential for ignition of surface contaminants. Visit www.torchwear.com.

TOP 5 TOOLS The Top 5 Favorite Tools of Top Technicians Dan Uricoli, Owner-Operator Dan’s Auto Repair & Tire Margate, FL Streamlight Stinger LED Flashlight The first tool I reach for is my Stinger LED flashlight. Best I’ve had in 38 years. Matco Tools Mini Code Reader The second tool I most likely reach for is my Matco Mini Code Reader. Very easy and clears codes. I haven’t found a vehicle it won’t read. ALLDATA The third most likely tool would be ALLDATA. No explanation needed. Power Probe This spot (#4) belongs to the Power Probe. Easiest and most versatile test light I have owned. Brake Lining Gauge Set It’s a toss up for #5. But I’ll choose the Brake Lining Gauge Set. Easy to explain to customers with the red, yellow and green feelers. I keep a new brake pad handy also for comparison. It really helps.

Arthur Irwin, Producer Two Guys Garage Swansea, MA Quick Trick Alignment Pro I can’t afford high-end alignment equipment, so with the Quick Trick Alignment product, I can still take care of my customers. Actron C9575 Scanner I check all the customers’ cars, whether they need it or not, and I can look at live data for potential problems, like an O2 sensor going bad. Right Angle Die Grinder I use the Right Angle Die Grinder for jobs from cleaning up a surface for a gasket, to brake jobs to cleaning up parts. CRC Freeze Off I know, not really a tool, but it is in the sense that if the nut or bolt is rusty — especially wheel bearing hub assemblies — it works like a tool. Power Probe The best and easiest way to test an electronic component, to know if it’s bad, or if it’s just a wire or fuse; saves $$$. TS
