damage to steel pistons may result.

Asbestos fiber dust may be present on brake

and clutch assemblies and is hazardous to

health if inhaled.
Brake and clutch assemblies should be

cleaned using a vacuum cleaner

recommended for use with asbestos fibers

such as a brake/clutch/service vacuum. The

bag must be labeled per OSHA instructions,

sealed, and the trash hauler notified as to the

bag’s contents.
If the vacuum suitable for asbestos is not

available, cleaning should be done wet. If dust

generation is still possible, technicians should

wear goverment-approved toxic dust purifying

respirators. Failure to follow these

instructions may result in personal injury.

the rotor being careful not to bend them.

2. Install the inner (7) and outer (8) pads to the

abutment bracket (1), against the inner and outer

surface of the brake disc respectively.

3. Lower the brake calliper housing, ensuring that:

the piston boots (4&5) do not get caught

between the piston and inner pad (7).

4. Install and tighten the new guide pin bolt (3) to the

correct torque specification.
NOTE: Do not wedge anything between the

guide pin hex and the caliper as it could cause

REMOVAL AND INSTALLATION (Continued)

3. Disconnect hose. Discard copper sealing rings.

2. Remove the caliper assembly from the spindle

and the rotor, as previously described in this

section. If the caliper does not require servicing, it

is not necessary to disconnect the brake hose.

Position the caliper out of the way, and support it

with a wire to avoid damaging the caliper or the

hose. Handle the rotor, linings and caliper

assemblies carefully to avoid deformation, nicking,

scratching or contamination.

3. Remove the rotor from hub.
Installation
1. Position the rotor on the axle flange.

NOTE: Ensure that all mounting surfaces are

clean and free from contamination which could

cause possible disc runout.

between the piston and inner pad (7).

3. Install and tighten the new guide pin bolt (3) to the

correct torque specification.
NOTE: Ensure hose is engaged to bracket prior to

fitment of banjo bolt. Check routing for correct

clearance on completion.
NOTE: Do not wedge anything between the guide

pin hex and the caliper as it could cause incorrect

alignment of the free sliding of the caliper relative

to the anchor plate.

4. Reconnect new brake hose, using new, dry,

sealing washers. Tighten attaching bolt to the

correct torque specification ensuring hose routing

is removed.
