BRAKE PAD REPLACEMENT:
The brake pads should be inspected periodically for wear. If the pads need replacement, it may be done in the following manner.
Remove the brake caliper from its mounted position over the rotor. Note the exact amount of shims and washers used on each
mounting bolt so that the caliper may be re-installed without having to realign it.
Using a screwdriver, spread the old brake pads in order to retract the pistons. Avoid cocking the pistons in their bores which may
result in damage to the caliper. Be aware that when retracting the pistons, fluid is being forced back into the master cylinder fluid
reservoir. During this process it may be necessary to remove the excess fluid, if the reservoir fills up.
Using needle nose pliers, remove the retaining clip from the inboard side of the caliper. Remove the pad retaining pin and slide the
brake pads out (one at a time) from the bottom of the caliper. The anti-rattle spring should stay in place and does not need to be
removed.
A suitable brake cleaner may be used at this time to remove dirt and brake dust from the pad and rotor cavity areas of the caliper.
After the brake caliper is clean, insert the new brake pads (one at a time) with the friction material facing each other. Simultaneously
push upward on the brake pads (to align the pin holes in the pads and caliper housing) and insert the pad retaining pin. Install the
retaining clip, assuring that it seats properly in its groove.
As a good maintenance practice, the caliper bridge bolts (the four bolts holding the caliper halves together) should be” retorqued”
to 130-140 in/lb (11-12 ft/lb).
Re-install the caliper over the rotor using the exact bolt, shim and washer combinations that were removed earlier. The mounting
bolts should be installed as previously described in the assembly instructions.
Verify that the brake fluid is filled to the proper level.
Use the same cautions listed earlier in the assembly instructions before operating the vehicle.

Brake Testing
• Make sure pedal is firm: Hold firm pressure on pedal for several minutes, it should remain in position without
sinking. If pedal sinks toward floor, check system for fluid leaks. DO NOT drive vehicle if pedal does not stay firm
or can be pushed to the floor with normal pressure.
• At very low speed (2-5 mph) apply brakes hard several times while turning steering from full left to full right, repeat
several times. Remove the wheels and check that components are not touching, rubbing, or leaking.
• Carefully examine all brake components, brake lines, and fittings for leaks and interference.
• Make sure there is no interference with wheels or suspension components.
• Drive vehicle at low speed (15-20 mph) making moderate and hard stops. Brakes should feel normal and
positive. Again check for leaks and interference.
• Always test vehicle in a safe place where there is no danger to (or from) other people or vehicles.
• Always wear seat belts and make use of all safety equipment.
WARNING • DO NOT DRIVE ON UNTESTED BRAKES
BRAKES MUST BE TESTED AFTER INSTALLATION OR MAINTENANCE
