Solution

1. Preparation

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

2. Remove Wheel Assembly

Sub-steps:
1. Loosen lug nuts on the front or rear wheels.
2. Raise the vehicle using a jack and securely support it with jack stands.
3. Remove lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket and ratchet.
2. Carefully slide the caliper off the rotor and support it with a wire or bungee cord (do not hang by the brake line).
3. Remove old brake pads from the caliper bracket.
4. Compare new pads with old pads for thickness and shape.
5. If necessary, use a C-clamp to compress the caliper piston fully.
6. Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
1. Check rotors for warping or scoring; replace if necessary.
2. Remove the caliper bracket bolts and slide off the bracket if replacing rotors.
3. Remove the rotor from the hub (may require tapping with a rubber mallet).
4. Clean the hub surface and install the new rotor, ensuring proper alignment.

5. Reassemble and Bleed Brake System

Sub-steps:
1. Reattach the caliper bracket and caliper with bolts, torqueing to manufacturer specifications.
2. Reinstall the wheel and lug nuts, tightening to proper torque.
3. Lower the vehicle and pump the brake pedal several times to seat the pads.
4. Bleed the brake system using a brake bleeder kit to remove any air; start with the wheel farthest from the master cylinder.
