Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the battery to ensure safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts of the affected wheel.
Lift the vehicle using a jack and secure with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the brake pads, avoiding strain on the brake line.
Inspect the brake pads; if they are worn down to the metal or damaged, replace them.
If replacing, install new brake pads by sliding them into the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Check the brake rotor for grooves or warping. Use a caliper gauge for measurement.
If the rotor is within specifications, it may be resurfaced. If not, replace it with a new rotor.
If resurfacing, ensure the rotor is cleaned and reinstalled properly with the correct torque specifications.

5. Reassemble Components

Reinstall the brake caliper over the new pads and align it with the mounting bracket.
Tighten caliper bolts to the manufacturer’s specified torque (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper seating of the brake pads.
Lower the vehicle and perform a final check of all connections.
