Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Jack up the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check thickness; replace if less than 3mm.
- Look for uneven wear patterns.
Replace Brake Pads:
- Remove caliper bolts with a socket wrench.
- Slide the caliper off the rotor; support it to avoid straining the brake line.
- Remove old pads from the caliper bracket.
- Install new brake pads in the caliper bracket.
- Reattach the caliper over the new pads and torque bolts to manufacturer's specifications (usually around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors

Check Rotors:
- Measure thickness and look for any scoring or warping.
Replace Rotors (if necessary):
- Remove caliper bracket bolts and lift the caliper bracket off.
- Slide the rotor off the hub; it may require tapping with a rubber mallet.
- Install new rotor, ensuring it is properly seated on the hub.
- Reinstall the caliper bracket and torque bolts to specifications.

5. Check Brake Fluid

Inspect brake fluid level; top off with the correct type (usually DOT 3 or DOT 4).
If fluid is contaminated, consider flushing the brake system.

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to specifications (usually around 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper function before driving.
