Solution

1. Preparation

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

2. Remove Wheel

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

3. Inspect and Replace Brake Pads and Rotors

Sub-steps:
1. Inspect the brake pads for thickness; replace if they are below the manufacturer’s specifications.
2. Check the rotors for scoring, grooves, or warping; if warped beyond tolerance, replace them.
3. If replacing rotors, remove the caliper bolts and lift the caliper away from the rotor.
4. Remove the old rotor by unscrewing the retaining screws if applicable or pulling it off the hub.
5. Install the new rotor, ensuring it is seated properly.
6. Reinstall the caliper over the new pads and rotor, torque caliper bolts to the manufacturer’s specifications.
Tools Required: Socket set, torque wrench, brake cleaner.

4. Reinstall Wheel

Sub-steps:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts before lowering the vehicle.
3. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications in a criss-cross pattern.
Tools Required: Torque wrench.

5. Test Brake System

Sub-steps:
1. Start the vehicle and pump the brakes to ensure proper engagement.
2. Test drive the vehicle at low speeds to check for any vibrations or noises.
Safety Warnings: Ensure brakes are functioning correctly before driving at higher speeds.
