Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Engage the parking brake and wear safety goggles.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Slide the caliper off the rotor and suspend it using a bungee cord to avoid strain on the brake line.
Remove the old brake pads and inspect for wear; replace if they are less than 1/8 inch thick.
Apply brake grease to the backing of the new brake pads and install them in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotors for scoring; if scored, they should be replaced or resurfaced.
Remove the caliper bracket to access the rotors.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor, ensuring it is properly seated.

5. Reassemble the Braking System

Reinstall the caliper bracket and ensure torque specifications are followed (typically 20-30 ft-lbs).
Slide the caliper back over the new brake pads and secure it with the caliper bolts.
Replace the wheel and lower the vehicle.

6. Final Checks

Pump the brake pedal to seat the pads against the rotors.
Check brake fluid levels, topping off if necessary with the manufacturer-recommended fluid.
