Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

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

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Measure rotor thickness and check for warping using a dial indicator.
If warped or below specification, remove the rotor by loosening the retaining screws and sliding it off the hub.

B. Replace Brake Pads

Remove the caliper bolts with a socket set and carefully slide the caliper off the rotor.
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are correctly positioned.

C. Reinstall or Replace Rotors

If rotors were replaced, install new rotors on the hub and secure them with retaining screws.
Reinstall the caliper over the new rotor and tighten caliper bolts to the manufacturer’s torque specification.

4. Reassemble and Test

Reinstall the wheel and tighten lug nuts in a crisscross pattern.
Lower the vehicle from the jack stands.
Test brake function by pressing the brake pedal several times to seat the pads.
