Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Remove Wheel and Inspect Brake Components

Use a lug wrench to loosen the lug nuts, then raise the vehicle with a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Rotors

Inspect the rotors: Use a dial indicator to check for warping. If warped beyond specifications (usually 0.004 inches), replace the rotors.
Remove the caliper: Unbolt the caliper from the bracket and suspend it with a bungee cord to avoid straining the brake line.
Remove the rotor: Unscrew the retaining screws (if applicable) and slide the rotor off the hub.
Install new rotors: Place the new rotor on the hub, ensuring it's seated correctly. Reinstall any retaining screws.

4. Replace Brake Pads

Remove old pads: Take out the old brake pads from the caliper bracket.
Compress caliper piston: Use a C-clamp to compress the caliper piston back into the caliper housing.
Install new pads: Place new brake pads in the caliper bracket in the correct orientation.

5. Reassemble Brake Components

Reattach the caliper over the new pads and torque the mounting bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Brake System Bleed

Reconnect the battery if it was disconnected.
Bleed the brake system to remove any air in the lines, starting from the farthest wheel from the master cylinder.
Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve on each caliper.

7. Final Checks

Recheck all fasteners for proper torque.
Lower the vehicle and perform a test drive to ensure proper brake function.
