Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle.
Secure it with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel and access the brake assembly.

4. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads; replace if less than 3mm.
- Look for uneven wear or glazing.
Replacement:
- Remove the caliper bolts using a socket wrench, then slide the caliper off.
- Remove the old brake pads from the caliper bracket.
- Compress the caliper piston using a C-clamp or brake caliper tool.
- Install new brake pads in the caliper bracket.
- Reattach the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (usually around 25-35 Nm).

5. Inspect and Replace Rotors (If Necessary)

If rotors are scored or below minimum thickness, replace them:
- Remove the caliper and bracket as previously described.
- Remove the rotor by removing the retaining screws (if applicable) and sliding it off the hub.
- Install new rotors, ensuring they are properly seated.
- Reinstall caliper bracket and caliper.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and then torque lug nuts to manufacturer specifications (typically 100-120 Nm).

7. Test Brake Function

Pump the brake pedal to ensure the caliper pistons seat properly and check for any noises.
