Assembling the parking brake
1. Clean the parts carefully.
IMPORTANT!
The friction surfaces must not come into contact with oil or grease, as
this will seriously reduce brake force.
2. Assembly of the brake is the reverse of dismantling.
3. Bear in mind the following:
- The hub of the friction disc (e) must fit the corresponding hole in
the magnet housing.
- Play must be set correctly. Some adjustment may be necessary.
Adjusting play
1. Play between the pressure plate (c) and magnet housing (b) is ad-
justed using the adjusting screws (d).
2. Play may not exceed the maximum permitted value before adjust-
ment is required. Use a feeler gauge to measure it.
Maximum permitted play: 0.50 mm
Nominal play: 0.3±0.1 mm.
3. Slightly loosen the mounting screws (g).
4. Adjust play using the adjusting screws (6).
5. Turn anticlockwise to increase play and clockwise to reduce it.
6. Tighten the mounting screws (g) to 20 Nm.
7. Check play again once the screws have been tightened.
8. Repeat the adjustment stage until play is correct.
9. Check play all the way around the pressure plate. The maximum
permitted deviation from the play setting is 0.075
mm.
