Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery for safety.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts of the wheel.
2. Lift the vehicle with a jack and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner.
Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor.
3. Inspect the brake pads for wear; replace if they are worn down.
4. If replacing, remove old pads and install new ones ensuring they are properly seated.
5. Clean the caliper and rotor with brake cleaner.

4. Inspect and Replace Brake Rotors

Tools Required: Brake rotor puller (if necessary), torque wrench.
Sub-steps:
1. Remove the rotor from the hub by unscrewing any retaining screws.
2. Inspect the rotor for grooves, rust, or warping; replace if damaged.
3. Install new rotor onto the hub.
4. Torque the rotor retaining screws to the manufacturer’s specifications.

5. Reassemble Braking System

Sub-steps:
1. Reinstall the caliper over the new brake pads and rotor.
2. Tighten the caliper bolts to the manufacturer’s specified torque value.
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Sub-steps:
1. Lower the vehicle off the jack stands using the jack.
2. Tighten the lug nuts in a criss-cross pattern to ensure even pressure.
3. Reconnect the battery.
