Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor without disconnecting the brake line.
Inspect brake pads for wear; if the friction material is less than 3mm, replace them.
If replacement is needed, remove the old pads and install new ones, ensuring they are oriented correctly.

4. Inspect and Resurface/Replace Rotors

Check the rotor surface for any grooves, scoring, or warping.
If damaged, either resurface the rotors or replace them with new ones.
If resurfacing, follow the manufacturer's specifications for thickness limits.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (typically between 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts in a criss-cross pattern to the manufacturer’s torque specifications (usually around 80-100 ft-lbs).
Reconnect the negative battery terminal.
