Brake Pads

Start by checking the brake master cylinder fluid level before work. Lower the fluid amount to reach the midpoint when the reservoir shows more fluid than required. Lift the vehicle to its support point and take off the rear tire and wheel set from the car. Install one hand-tightened lug nut over the rotor to keep it on the hub and use a c-clamp to push down on the caliper Piston for space. Lower the caliper gently by moving its top bolt to view the brake pads without taking apart the entire assembly. Carefully remove both brake pads from their brackets and also take away the two holding clips and check the caliper bracket nuts. Substitute any damaged hardware found. Look at the dust boot inside the caliper as well as examine the caliper bolts for breakage or rust. Replace these parts with fresh items when necessary. Place the Piston at the bottom of the caliper bore with a c-clamp but keep it away from the Piston and boot. Mount the two retainers to both sides of the caliper bracket with attention to the wear sensor placement on the outside pad at the rear of the wheel during normal driving direction. Thread the pads (9 and 10) onto the caliper bracket after you position the caliper upwards on the pads. Apply silicone grease to both bolt parts before putting in the upper caliper bolt and securing it at 44 nm (32 ft. Lbs.) torque. Put the new tire and wheel on the axle hub then match the tire marks while lowering the car. During engine shutdown gradually push the Brake Pedal to 2/3 position and release it slowly several times to correctly position brake caliper parts. Complete the filling procedure of the brake reservoir and smooth out Brake Pad-to-rotor contact.

Clean the outside surface of the caliper boot with denatured alcohol, then bottom the piston into the caliper bore using a C-clamp and a metal plate or wooden block to avoid damage.

Remove the wheel lug nut retaining the rotor, install the rear tire and wheel assembly, aligning previous marks, and lower the vehicle.

Use new bolts during installation.

Swing the caliper upward around the pads.

Remove the pads from the caliper bracket and the two retainer slides.

The upper caliper bolt and boot with silicone grease.

Burnishing should be done whenever the disc brake rotors have been refinished or replaced, or whenever the disc brake pads have been replaced.

Raise and support the vehicle, then remove the rear tire and wheel assembly.

The disc brake mounting, hardware, and caliper dust boot.

Use a C-clamp and an old brake pad or wooden block to avoid damage.

Inspect the fluid level in the brake master cylinder reservoir; if it is above the midway point, remove fluid to reach that point.

Remove the support and reposition the caliper over the front pads.

Raise and support the vehicle, then remove the tire and wheel.
