Solution

1. Preparation

Gather tools and materials needed.
Ensure the vehicle is on a level surface and parked securely.
Use jack stands to secure the vehicle after raising it.

2. Remove the Wheel

Tools Required: Lug wrench, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts slightly while the car is on the ground.
2. Raise the vehicle using the jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Pads

Tools Required: Flashlight (optional), brake pad gauge.
Sub-steps:
1. Visually inspect the brake pads for thickness; they should be at least 3mm thick.
2. Check for uneven wear or damage to the pads.
3. If necessary, measure pad thickness with a brake pad gauge.

4. Replace Brake Pads (if needed)

Tools Required: Socket set, torque wrench, brake cleaner, anti-squeal lubricant.
Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and suspend it with a wire (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Clean the caliper and bracket with brake cleaner.
5. Install the new brake pads into the caliper bracket.
6. Compress the caliper piston using a C-clamp to allow the caliper to fit over the new pads.
7. Reinstall the caliper and secure it with the caliper bolts, tightening to manufacturer specifications (typically around 20-25 ft-lbs).

5. Reassemble and Test

Tools Required: Lug wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle off the jack stands.
3. Tighten the lug nuts to the manufacturer's torque specifications (typically around 76 ft-lbs).
4. Pump the brake pedal a few times to seat the pads before driving.
