Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

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

3. Inspect and Remove Brake Components

Inspect Brake Pads: Check the thickness and condition of the brake pads.
Remove Caliper: Use a socket wrench to unbolt the caliper from the bracket. Support it with a bungee cord to avoid stress on the brake line.
Remove Brake Pads: Slide the brake pads out of the caliper bracket.

4. Replace Brake Pads and Inspect Rotors

Install New Brake Pads: Slide the new brake pads into the caliper bracket.
Inspect Rotors: If needed, replace or resurface the rotors based on their condition. Use a micrometer to measure rotor thickness.
Reinstall Caliper: Position the caliper over the new pads and bolt it back onto the bracket.

5. Reassembly

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
Check brake fluid level and top off if necessary.
