2
Check the brake rotors for scoring, warping, or surface rust.
3
Examine brake calipers for proper operation and any signs of leakage.
4

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Lift the vehicle and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; if they are worn down to less than 3mm, they need replacement.
- Look for uneven wear patterns indicating caliper issues.
Replace Brake Pads:
- Remove the caliper by unscrewing the caliper bolts using a socket set.
- Slide the caliper off the rotor and suspend it with a wire to prevent strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors

Inspect Brake Rotors:
- Check for deep grooves or warping; if damaged, they must be replaced.
Replace Brake Rotors:
- Remove the caliper bracket if necessary, using a socket set.
- Slide the old rotor off the hub.
- Clean the hub surface with a wire brush to ensure proper seating of the new rotor.
- Install the new rotor and secure it if required by the vehicle design.

5. Reassemble Components

Reattach the caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer's torque specification (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a star pattern.

6. Test Brake System

Before driving, pump the brake pedal several times to seat the new pads properly.
Check brake fluid levels again and top off if necessary.
