Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical issues while working.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set, then take off the wheel.

3. Inspect and Replace Brake Components

A. Brake Rotor

Inspection: Check the rotor for warping using a dial indicator.
Replacement: If warped, remove the caliper by unscrewing the caliper bolts. Remove the rotor by pulling it off the hub.
Install New Rotor: Place the new rotor onto the hub and secure it.

B. Brake Pads

Inspection: Assess the thickness of the brake pads.
Replacement: If pads are worn unevenly, remove the caliper bracket and replace the pads with new ones, ensuring proper orientation.

4. Reassemble Components

Reattach the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and torque the lug nuts to the specified value (usually around 100-150 ft-lbs).

5. Final Checks

Reconnect the battery and perform a brake system check.
Pump the brake pedal to ensure proper engagement before driving.
