Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the appropriate socket.
2. Carefully lift the caliper off the rotor without disconnecting the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Check the caliper slide pins for lubrication; replace or lubricate if necessary.
5. Install new brake pads, ensuring they are properly aligned.
6. Reinstall the caliper and secure the bolts to the specified torque (usually around 20-25 lb-ft).
Tools Required: Socket set, torque wrench, brake cleaner.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are scored or warped, remove them from the hub by unscrewing the retaining screws (if applicable).
2. Install new rotors, ensuring they are clean and free of grease.
3. Tighten the rotor screws to manufacturer specifications.
Tools Required: Socket set, torque wrench, rotor puller (if needed).

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle to the ground and fully tighten the lug nuts in a crisscross pattern to the specified torque (usually around 80-100 lb-ft).
3. Pump the brake pedal several times to ensure proper brake pad seating.
Safety Warnings: Ensure the vehicle is securely lifted before working under it.
