Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle with a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner, C-clamp
Sub-steps:
1. Remove the caliper by unscrewing the bolts holding it in place.
2. Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pad backing plates for damage and replace if necessary.
5. Apply brake cleaner to the caliper and rotor to clean any debris.
6. Use a C-clamp to compress the caliper piston back into the caliper housing.
7. Install new brake pads into the caliper bracket.
8. Reattach the caliper over the new pads and tighten the caliper bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench
Sub-steps:
1. If the rotors are damaged, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
2. Install new rotors, ensuring they are aligned properly.
3. Reattach any retaining screws and torque to specifications.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Replace the wheel and hand-tighten the lug nuts.
2. Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications.
3. Pump the brake pedal a few times to ensure the brake pads are seated correctly.
