Solution

1. Preparation

Gather all tools and parts required.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear tires for safety.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

a. Check Brake Pads

Remove the caliper by unscrewing the caliper bolts.
Inspect brake pads for thickness and even wear; replace if worn unevenly.

b. Inspect Brake Rotors

Remove the rotor if warped (take note of the mounting hardware).
Use a dial indicator to check the rotor for warping; if warped beyond specs, replace the rotor.

c. Replace Components

If brake pads are worn, install new pads by sliding them into the caliper bracket.
If rotors are damaged, install the new rotor onto the hub and secure it with the appropriate hardware.

4. Reassemble and Test

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value in a crisscross pattern.

5. Final Inspection

Pump the brake pedal to ensure proper pad seating.
Check brake fluid level and top off if necessary.
