2
Check brake rotor surface for damage or warping.
3
Examine brake calipers for proper movement and functionality.
4

Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and engage the parking brake.
Gather tools and safety equipment: gloves, safety glasses, jack, jack stands, lug wrench, socket set, brake cleaner, and a torque wrench.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are less than 3mm thick, they should be replaced.
Removal:
- Remove the caliper mounting bolts using a socket.
- Carefully slide the caliper off the rotor and support it with a bungee cord or similar to avoid straining the brake line.
Replacement:
- Remove old brake pads from the caliper bracket.
- Install new brake pads in the same orientation as the old ones.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check the rotors for scoring, grooves, or warping.
Removal:
- If warped or damaged, remove the caliper bracket by unscrewing its bolts.
- Slide the rotor off the hub.
Replacement:
- Install the new rotor onto the hub, ensuring it sits flush.
- Reattach the caliper bracket and torque bolts to specifications (typically 80-100 ft-lbs).

5. Reassemble and Test

Reinstall the caliper over the new pads and secure it with the caliper mounting bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
Pump the brake pedal a few times until a firm pedal feel is achieved and check for any leaks.
