04 Brakes Foot brake

Measurements and checks Checking the lubrication pressure and flow of the service brakes (after valve) Test conditions: – Oil temperature: 60°C. – Engine running at 2 200 rpm.

– Transmission engaged (tractor made safe on stands).

– No actuator activated (spool valves, steeering, PTO, etc.).

• Fit the flowmeter and pressure sensors of kit Nr. 00 0178 310 0 and 00 0178 320 0.

• Connect tester No.00 0178 310 0 to the pressure and flow sensors.

The values measured must be 13 l/min and 2 bars. These values are given as an indication only.

Checking pressure of the service brake (master cylinder + boosters) and trailer hydraulic, pneumatic brake Test conditions: – Engine running idle at 2 200 rev/min.

– Transmission oil temperature: 60°C. – Coupled brake pedals.

– Fit the pressure sensors of kit No.00 0178 310 0 onto a T on the level of the feed of one of the 2 brake pistons, one onto the hydraulic brake fitting of the "8036" trailer, and another onto the trailer pneumatic brake fitting.

04 Brakes Foot brake

– Connect tester No.00 0178 310 0 onto the pressure sensors.

– Actuate the brakes over the entire stroke of the pedals.

– Record pressure, which must be 70 bars for service brakes fitted with "boosters". The trailer hydraulic braking pressure is 140 +/- 5 bars. The trainler air braking pressure is 8 bars.

Note: Following this check, the brake system must be drained (Refer to chapter "04" in the preparation file).

These values are given as an indication only.

Use the kit n°00 0178 310 0 to perform measurements and read then on a computer.

The point is to display the curves of the different types of braking (service, brake, trailer hydraulic brake, air brake) to see if the tractor brakes the trailer properly.

The graph below shows the braking of the master cylinder and "booster" with trailer hydraulic and pneumatic braking.
