Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel and Brake Components

Using a socket set, loosen and remove the lug nuts.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Rotors

Inspect Rotors: Measure thickness with a micrometer; if below specification or warped, replace.
Remove Rotors: Unscrew the caliper mounting bolts and slide the caliper off the rotor.
Replace Rotors: Install new rotors ensuring they are clean and free of debris.

4. Inspect and Replace Brake Pads

Inspect Pads: Check thickness; if worn unevenly, replace both sets (front and rear) for balance.
Remove Pads: Slide out the old pads from the caliper bracket.
Install New Pads: Apply brake grease on the backing and install new pads.

5. Reassemble and Torque Components

Reattach the caliper over the new pads and secure it with the mounting bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (usually around 100-150 ft-lbs).
