Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift Vehicle

Use a floor jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure with jack stands to ensure stability.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Ensure the wheel is stored safely to prevent damage.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check the brake rotors for warping or scoring using a dial indicator. If warped beyond specifications, proceed to replace.
Replacement:
1. Remove caliper bolts using a socket set.
2. Slide the caliper off the rotor, and support it with a bungee cord to avoid stress on the brake line.
3. Remove the old rotor by unscrewing any retaining screws (if equipped) and sliding it off the hub.
4. Clean the hub surface with a wire brush to ensure proper seating of the new rotor.
5. Install the new rotor, ensuring it fits snugly onto the hub.

5. Replace Brake Pads (if necessary)

Remove the brake pads from the caliper bracket.
Use a C-clamp to compress the caliper piston back into the caliper housing.
Install new brake pads, ensuring they are oriented correctly.
Reattach the caliper over the new pads and secure with caliper bolts, tightening to manufacturer specifications (typically around 25-35 ft-lbs).

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (typically around 100-150 ft-lbs).
Dispose of old brake components according to local regulations.
