Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts with a lug wrench while the vehicle 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.
Tools Required: Lug wrench, jack, jack stands

3. Inspect Brake Components

Sub-steps:
1. Examine the brake pads for thickness; replace if they are worn down to less than 1/8 inch.
2. Check the brake rotors for grooves, rust, or warping; replace if necessary.
3. Ensure the calipers are not sticking and are properly functioning.
Tools Required: Caliper tool, micrometer (for rotor thickness)

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Remove the caliper bolts using a socket set and slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. If replacing rotors, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
4. Install new rotors if applicable, ensuring they are properly seated.
5. Install new brake pads in the caliper bracket.
6. Compress the caliper piston using a caliper tool to allow for new pads.
7. Reattach the caliper over the new pads and torque the bolts to the manufacturer’s specifications.
Tools Required: Socket set, torque wrench, caliper tool

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and then torque the lug nuts to the specified torque value.
3. Pump the brake pedal several times to seat the brake pads before driving.
Tools Required: Torque wrench
