Fitting Instructions for Brake Discs (Rotors) and Brake Pads    

Important General Information:

-           Brakes are safety critical and must be fitted by qualified persons only.

-           Special instructions issued by the vehicle and brake manufacturer must be observed.

-           Brake discs (rotors) should be replaced as axle sets.

-           In general, brake pads must be replaced at the same time to avoid poor brake operation and performance.

-           Ensure suitable PPE is worn

-           Ensure correct tools and equipment are used

Fitting:

-           Once the vehicle is in a safe position (on a suitable lift or axles stands with wheels chocked )

-           Remove the wheels in accordance with manufacturer’s instructions.

-          Clean off brake dust from the brake system using a suitable brake cleaner or vacuum. Compressed air must not be used. If inhaled, brake dust can be harmful to health.

-           Remove brake caliper and secure to the vehicle with appropriate means. It is advisable to complete one side at a time as components can be handed.

-          Calipers must not be left to hang on the brake hose, as this can damage the hose leading to complete brake failure.

-           Crack bleed nipple and attached a suitable bleed bottle then push piston back with a suitable wind back tool or pad spreader.

-           Remove caliper carrier (bracket)

-           Clean brake pad contact points on the caliper carrier and caliper to ensure correct brake pad alignment.

Failure to do this can lead to poor brake performance, brake noise and brake judder.   

-           It is advised that any brake pad fittings, springs, shims, bolts etc. are replaced.

-           Once the disc is removed, clean the hub face meticulously so it is free from corrosion, dirt and contamination. Hub faces should exhibit a bright metallic finish.

-           Measure hub run out with a suitable DTI kit. Run out should be no more than 0.03mm

-           Refit new disc, observing rotation orientation, using fixing screw torqued to manufacturers specification.

Brake judder caused by incorrect installation will void any warranty.

-           Refit brake caliper and carrier, observing specified torque settings, along with new brake pads. Lightly grease pad contact points at each end of the pad (do not grease pad backplate unless specified by the brake or vehicle manufacturer). Use only authorised or non-metallic brake grease.
