Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle with a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Check for warping using a dial gauge; if warped beyond manufacturer specifications, replace.
If the rotors are within specs but worn, consider resurfacing them.

B. Replace Brake Pads

Remove caliper bolts and slide the caliper off the rotor.
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly.

C. Replace Rotors (if necessary)

Remove the caliper bracket if rotors are to be replaced.
Slide the old rotor off and replace it with the new rotor.
Reattach the caliper bracket and caliper.

4. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (typically 100-120 ft-lbs).
Reconnect the negative battery terminal.
