Solution

1. Preparation

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

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly before lifting the vehicle.
2. Use the jack to lift the vehicle 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
Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully lift the caliper off the rotor without disconnecting the brake line.
3. Inspect the brake pads for thickness; replace if worn down (less than 3mm).
4. If replacing, apply brake cleaner to the rotor and pads, then install new pads.
5. Use a C-clamp to compress the caliper piston back into the caliper housing.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench
Sub-steps:
1. If rotors are scored or warped, remove them from the hub.
2. Install new rotors, ensuring they are clean and free of grease.
3. Torque the rotor bolts to the manufacturer’s specifications.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Reattach the caliper and tighten the caliper bolts.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
