Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment: gloves and safety glasses.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it (typically 2 bolts).
Slide the caliper off the rotor and secure it without straining the brake line.
Remove the old brake pads from the bracket.
Compare the thickness of the old pads with new ones; replace if worn below manufacturer specifications.
Apply brake lubricant to the backing of the new pads to prevent noise.
Reinstall the new brake pads.

4. Inspect and Resurface/Replace Rotors

Check the rotor for scoring or damage. If warped, consider resurfacing or replacing.
To resurface, use a brake lathe according to manufacturer specifications.
If replacing, remove the rotor by unbolting it from the hub and install the new rotor.

5. Reassemble Brake Components

Reattach the caliper over the new pads and rotor, ensuring it slides freely.
Torque caliper bolts to the manufacturer's specified torque settings (usually around 20-30 ft-lbs).
Reinstall the wheel and torque lug nuts to specifications.

6. Final Steps

Lower the vehicle and remove jack stands.
Pump the brake pedal several times to seat the pads against the rotor.
Check brake fluid level and top off if necessary.
