Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts during repair.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts slightly while the wheel is still on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check the thickness of the brake pads. Replace if they are worn down below the manufacturer’s specifications.
Inspect Brake Rotors:
- Use a runout gauge to measure the rotor for warping. If warping exceeds specifications, replace the rotors.
- If the rotors are within specifications, consider resurfacing them if applicable.
Replace Brake Pads:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Replace old brake pads with new ones ensuring they are properly seated.
- Reinstall the caliper and torque the bolts to manufacturer specifications (typically 25-35 Nm).
Replace Brake Rotors (if necessary):
- Remove the old rotor by sliding it off the hub and install the new rotor. Torque the retaining screws to specification (usually around 10 Nm).

4. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer’s specification (usually around 100 Nm).

5. Final Checks

Reconnect the battery.
Check brake fluid level and top up as necessary.
