Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Tools Required: Socket set, brake cleaner, torque wrench, jack and jack stands, safety glasses, gloves.
• Parts Required: Brake pads (if worn), brake rotors (if needed), brake grease.
• Safety Warnings: Ensure the vehicle is on a flat surface and use jack stands to support the vehicle securely.

2. Remove Wheel

• Loosen the lug nuts on the offending wheel with a socket set.
• Raise the vehicle using a jack and secure it with jack stands.
• Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

• Remove the brake caliper by unscrewing the mounting bolts. Support the caliper using a bungee cord or similar device to avoid strain on the brake line.
• Take out the old brake pads from the caliper bracket.
• Inspect the brake pads for wear; if they are below the manufacturer’s minimum thickness, replace them with new pads.
• Apply a thin layer of brake grease to the back of the new brake pads to reduce noise.
• Reinstall the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

• If the rotors are below the minimum thickness, or if they are warped, they need to be replaced.
• Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
• Install the new rotor and secure it according to manufacturer specifications.

5. Reassemble Components

• Reattach the brake caliper over the new brake pads and ensure it is secured tightly.
• Reinstall the wheel and tighten the lug nuts by hand.
• Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

6. Final Check

• Pump the brake pedal a few times to seat the brake pads correctly against the rotors.
• Check for any unusual noises before taking the vehicle for a test drive.
