Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts slightly without removing them.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Slide the caliper off the rotor and support it without stressing the brake line.
Remove the old brake pads and inspect the caliper for damage.
If necessary, replace the brake pads with new ones, ensuring they are oriented correctly.

4. Inspect and Resurface/Replace Rotors

Use a runout gauge to check the rotor for warping; if warped beyond specifications, replace the rotor.
If acceptable, use a brake lathe to resurface the rotors.
Clean the rotor surface before reinstallation.

5. Reassemble Components

Reinstall the caliper over the new pads and tighten caliper bolts to the manufacturer’s torque specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern to ensure even pressure.
