Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheel Assembly

Use a lug wrench to loosen the wheel lug nuts.
Raise the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor, supporting it with a bungee cord or similar tool to avoid straining the brake line.
Check brake pads for thickness; replace if they are worn below 3mm.
If replacing, install new pads by aligning them with the caliper bracket and pressing them into place.

4. Inspect and Replace Brake Rotors

Check rotors for warping or scoring; replace if necessary.
If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
Install the new rotor, ensuring it is seated properly.

5. Reassemble Components

Reattach the caliper over the new pads and rotor, securing it with caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification (typically 100-150 ft-lbs, check the owner's manual for specifics).

6. Final Checks

Reconnect the negative battery terminal.
Top off brake fluid if necessary and check for leaks around the caliper and brake lines.
