Wheel brakes:

Brake linings should be replaced when the warning threshold of the brake lining wear indicator is replaced.

Refer to FRONT BRAKES and REAR BRAKES .

Brake linings must always be replaced on both sides of any axle.

The friction faces of brake linings must not come into contact with oils or grease and if brake linings become contaminated with substances of this kind, they must be replaced.

In the case of rotation-dependent brake linings, make sure the arrow marking points in the direction of rotation of the brake disc for when the vehicle is moving forward. Brake linings with left/right markings must be installed on the respective vehicle side.

One-sided angled areas on the brake linings must be located on the disc contact side of the brake caliper for when the vehicle is moving forward.

Brake discs must not be scored or cracked; in addition, the minimum disc thickness, disc run-out, parallelism and surface roughness of the friction surfaces must not exceed or drop below the permitted values.

Refer to FRONT BRAKES and REAR BRAKES .

Always strip preservative off new parts before installation. With the rear brake discs, also strip preservative off brake drum on parking brake.

Brake drums must not be scored or cracked; in addition, the maximum drum diameter, radial runout and surface roughness of the friction surfaces must not exceed or drop below the permitted values.
