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.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen lug nuts slightly while the wheel is on the ground.
Raise the vehicle using the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads.
If worn below the manufacturer's specifications (usually 3mm or less), remove the caliper bolts.
Tools Required: Torque wrench, ratchet set
Carefully slide the caliper off the rotor and support it using a bungee cord or similar.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Resurface or Replace Rotors

Check the rotors for any grooves or uneven surfaces.
If damaged or below the minimum thickness specification, they should be resurfaced or replaced.
Tools Required: Brake rotor tool, micrometer (for measuring rotor thickness)
If resurfacing, follow the machine shop's specifications for thickness.

5. Reassemble and Reinstall Wheel

Slide the caliper back over the new brake pads and rotor.
Torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts in a star pattern.
