Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

Tools Required:

Jack and jack stands
Lug wrench
Brake caliper tool
Torque wrench
OBD-II scanner (if needed)

2. Remove Wheel

Loosen lug nuts slightly with the lug wrench.
Raise the vehicle using the jack and support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Rotors

Check rotor surfaces for warping; use a dial indicator if available.
If warped, replace rotors with new ones. If within specifications, proceed to clean.

B. Clean Rotors (if reusing)

Use brake cleaner to thoroughly clean the rotor surface.
Ensure all debris and dust are removed.

C. Inspect Brake Pads

Measure the thickness of the brake pads.
Replace pads if they are below the manufacturer's minimum thickness specification.

4. Reassemble Components

Reinstall the rotors and torque to manufacturer's specifications (usually around 80-100 ft-lbs).
Install new or cleaned brake pads into the caliper bracket.
Reattach the brake caliper and torque bolts to specifications (usually around 20-30 ft-lbs).

5. Reinstall Wheel

Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to specifications (usually around 80-100 ft-lbs).
