Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Tools Required: Socket set, torque wrench
Loosen lug nuts on the wheel you will be working on.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take the wheel off.

3. Inspect and Replace Brake Pads

Inspect the brake pads for thickness; replace if below 3mm.
Sub-steps:
1. Remove the caliper bolts using a socket.
2. Carefully slide the caliper off the brake rotor.
3. Remove the old brake pads from the caliper bracket.
4. Apply brake grease to the back of the new brake pads to reduce noise.
5. Install the new brake pads into the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Check the rotors for any signs of scoring or damage.
If damaged, either resurface or replace the rotors.
Sub-steps:
1. Remove the caliper bracket (if necessary) for rotor access.
2. Remove the rotor from the hub.
3. If resurfacing, follow the machine shop’s guidelines.
4. If replacing, install the new rotor ensuring it is seated properly.

5. Reassemble Components

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (typically 25-35 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
