Solution

1. Preparation

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

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle with the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Inspect brake pads:
- Check for thickness; replace if worn down to 3mm or less.
Inspect brake rotors:
- Look for signs of scoring, pitting, or warping. Measure rotor thickness with a micrometer and replace if below specified limits.
Check calipers:
- Ensure they are not sticking and that the pistons are moving freely.

4. Replace Brake Pads and/or Rotors

If pads need replacing:
1. Remove the caliper bolts using a socket set.
2. Gently slide the caliper off the rotor.
3. Remove old brake pads by sliding them out.
4. Install new brake pads, ensuring they are properly seated.
If rotors need replacing:
1. Remove the rotor by unscrewing any retaining screws and slide it off the hub.
2. Install the new rotor, ensuring it is properly aligned.

5. Reassemble Brake Components

Reattach the caliper over the new pads or rotor.
Torque the caliper bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).
Pump the brake pedal several times until it feels firm to ensure proper caliper operation.
