Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake cleaner, C-clamp or brake caliper tool.
Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor without disturbing the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any signs of damage or wear.
5. Clean the caliper and rotor with brake cleaner.
6. Use a C-clamp to compress the caliper piston back into the caliper housing.
7. Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench.
Sub-steps:
1. If the rotors are scored or warped, mark the orientation and remove them.
2. Install new rotors, ensuring they are properly aligned.
3. Torque the rotor bolts to the manufacturer’s specifications.

5. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the caliper over the new brake pads and torque bolts to manufacturer's specs.
2. Replace the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and then torque the lug nuts to the correct specification.
4. Pump the brake pedal several times to ensure proper brake engagement before driving.
