Replacement of complete brake cylinder
Disassembly
1. Remove the friction pads as described earlier.
2. Bend up the retaining plate and remove the two brake
retaining bolts from the steering knuckle housing.
Lift the brake away from the brake disc.
3. Disconnect the hose from the brake cylinder. Insert a
plug in the hose to prevent the escape of brake fluid
and also prevent the entry of impurities into the sys-
tern.
4. Remove the two springs which hold the cylinder in
place and remove the cylinder.
5. Clean the entire brake housing thoroughly.
NOTE
Take the opportunity to check for brake wear, es-
pecially on the hinge pin.
Reassembly
1. Insert the new brake cylinder in the brake body as-
sembly and refit the springs.
2. Remove the plug from the brake hose, fit a new cop-
per washer and tighten the hose securely in the cyl-
inder.
3. Put the brake housing in place and tighten the retain-
ing bolts. Remember to secure the bolts with the re-
taining plate.
WARNING
Make quite sure that the brake hose is not twisted.
If it is not mounted in a neutral position, slacken its
attachment at the wheel housing and then retighten
it in the correct position.
4.
Refit the friction pads, spring and new cotter pins as
described earlier.
NOTE
Fit a new spring if the old one seems to be exhausted.
5.
Bleed the brake system and pump repeatedly up and
down with the brake pedal in order to adjust the fric-
tion pads in against the disc. Top up with brake fluid
in the reservoir.
WARNING
Do not forget to pump repeatedly with the brake
pedal, as otherwise the pedal will go all the way
down when the brakes are applied.
