Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the process.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Use a dial gauge to measure the rotor runout. If the runout exceeds manufacturer specifications, the rotor should be resurfaced or replaced.
If rotors are found to be warped, replace them with new rotors.

B. Check Brake Pads

Remove the brake caliper by unscrewing the mounting bolts and sliding it off the rotor.
Inspect the brake pads for wear. If they are below the minimum thickness, replace them with new pads.

C. Examine Calipers and Components

Inspect the caliper slides for smooth operation. Clean and grease the slides if necessary.
Check for any leaks or damage in the caliper. Replace if needed.

4. Reassemble Components

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer torque specifications (typically between 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands and tighten the lug nuts to the proper torque specification (usually 75-85 ft-lbs).
Reconnect the battery.
