Guidelines for Installing Brake Lines

Guidelines for Installing Brake Lines

The brake lines used are manufactured in accordance with DIN 74234 and are only used with 4,75 mm outer diameter and 0,7 mm thickness.

Guidelines for Laying Brake Lines

1. Brake lines must be protected against external damage. 2. Line bends of r < 25 mm must not be used. To eliminate the danger of crosssectional restrictions, line bends must be manufactured in a cold forming process with line bending pliers. 3. Line end pieces must not be used. These could create air pockets. 4. To avoid chafi ng caused by line clamps, all clamps must be coated with shrink-resistant material (rubber, plastic, leather etc.)

Preparation of Brake Line Connections

1. The line connections must form a conical connection (“F” fl ange) with spigot FS M 10 x 1 to DIN 74 234. A fl anging device is required to make a compliant fl ange. 2. Cut the brake line with a saw at right angles, remove any splints and chippings from the inside and outside. Apply water-free pressurised air to the line. 3. Insert blocks (1) for line Ø 4,75 mm in the fl anging device, 45° side to the fl ange spindle (4). Insert the brake line in the block as far as the spacer pin (2). Fit the fl ange insert for line Ø 4,75 mm in the fl ange spindle (4) and create the fl ange. 4. Before tightening the spigot (line nut) coat the outer fl ange surface with brake fl uid.
