Brake Pads

Test the brake master cylinder reservoir before work; you can keep fluid levels unchanged when the reservoir sits at middle marks between top and bottom limits. Before working lift the vehicle and take out the tire with its attached wheel. Check brake caliper functionality and hold it in place through wire support to shield the brake hose from damage. Detach the caliper from its mounting bracket keeping the hydraulic brake hose linked, then push out the brake pads from the mounting bracket and throw away the anti-rattle clips. Examine the caliper brakes and connecting bracket before putting new anti-rattle clips onto both bracket sides and Brake Pad surfaces. Place the brake caliper first then wheel assembly before taking away safety measures during the vehicle descent. Press the Brake Pedal to its two-thirds mark while turning off the engine then release the pressure gradually to fully position brake caliper parts. Complete service by filling the brake fluid reservoir with fresh fluid then running the brake system to smooth out Brake Pad metal contacts on disc rotors.

Before starting to replace the brake pads on a 1500 series vehicle without nys check the brake master cylinder reservoir. If the fluid level sits at halfway between low and high marks no extra fluid needs to be removed but if it is above the halfway point bring it down to that level before continuing. Push the tire wheel assembly down first followed by an installation of a large c-clamp that compresses the Brake Caliper Piston against the caliper housing. Continue pushing the piston until it reaches the bore end with the cleam in place. Detach the brake caliper by removing its bolts and placing heavy mechanic's wire under the bracket to support it before disconnecting the hydraulic brake hose. Check both the caliper and caliper bracket by removing brake pads and their holders. To install the piston into caliper bores safely use a c-clamp and place an old Brake Pad or wooden piece on top of the piston to keep it from damaging the boot or piston while pushing through the bore. Use a flat tool to lightly raise the boot next to the piston and let out atmosphere within the boot to keep it lower than the piston surface. Install the Brake Pad retainers onto the caliper bracket while orienting the wear sensor on the leading top edge during forward wheel turning. Place the brake pads afterward. Use new brake caliper bolts to connect the component to the bracket and tighten them to 108 nm (80 ft. Lbs.). Replace the tire and wheel assembly afterward. When the engine is off apply medium brake pressure to around 2/3 of the pedal movement and release it slowly. Repeat this step until you reach a solid brake feel to correctly settle the brake caliper components. After filling the master cylinder with clean brake fluid complete the pedal feel process using the bake caliper bolts at 108nm (80ftlbs).

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

Refill it to the proper level with fresh brake fluid.

Use heavy mechanic's wire or an equivalent whenever it is separated from its mount while the hydraulic flexible brake hose remains connected.

With the engine off, gradually apply the brake pedal to about 2/3 of its travel, slowly release it, and repeat this process until a firm pedal is achieved.

Use an old brake pad, metal plate, or wooden block.

Inspect the fluid level in the brake master cylinder reservoir.

Attach the new anti-rattle clips to the caliper bracket, install the brake pads, and reattach the caliper to the bracket.

With the engine off, gradually apply the brake pedal to about 2/3 of its travel, then slowly release it, repeating this process until a firm pedal is achieved.

Fill it to the correct level with clean brake fluid.
