Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, socket set.
Safety Warnings: Ensure the vehicle is on a flat surface and securely lifted before starting work.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely to gain access to the braking system.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unbolting it from the bracket.
Carefully slide the caliper off the brake pads and hang it using a bungee cord or similar to avoid strain on the brake line.
Check brake pads for wear; if they are less than 1/4 inch thick, replace them.
If replacing, remove the old pads and install new ones, ensuring they are seated properly in the caliper bracket.

4. Inspect and Resurface or Replace Rotors

Check the brake rotors for any signs of scoring or warping.
If the rotors are below the minimum thickness or heavily damaged, remove them and replace with new rotors.
If the rotors are salvageable, use a brake lathe to resurface them according to manufacturer's specifications.

5. Reassemble Components

Reinstall the brake caliper over the new pads.
Secure it with the appropriate torque specifications (typically 25-35 ft-lbs, check specific model).
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle, then torque the lug nuts to the manufacturer’s specifications (usually around 75-80 ft-lbs).

6. Test Brakes

Press the brake pedal a few times to seat the brake pads against the rotor.
Check for any unusual noises or issues after reassembly.
