Brake Caliper Mounting Plate Replacement- Front
Brake Caliper Mounting Plate Replacement- Front
Use the brake caliper mounting plate in order to mount all of the stationary brake components. An L or R following the part number cast on the back
of the plates indicates left or right side mounting. Some plates may also have an L or R painted on the front.
Removal Procedure
Notice: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's mount and the hydraulic flexible brake
hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may
cause damage to the brake hose and in turn may cause a brake fluid leak.
1. Remove the brake caliper (3) from the mounting bracket and support the caliper with heavy mechanic's wire or equivalent. DO NOT disconnect
the hydraulic brake flexible hose from the caliper.
2. Remove the hub and brake rotor (7) assembly.
3. Remove the spindle to mounting plate nuts.
4. Remove the spindle/mounting plate cover.
5. Remove the brake caliper mounting plate.
6. Inspect the support rails for rust, corrosion, and wear.
7. Clean the support rails with a wire brush.
8. Inspect the brake caliper mounting plate for cracks or elongated bolt holes.
Replace the mounting plate if necessary.
