Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is cool before working on brakes.

2. Remove Wheel

Use a lug wrench to loosen wheel lug nuts.
Jack up the vehicle using a hydraulic jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper by unscrewing the caliper bolts using a socket set.
- Slide the caliper off the rotor carefully.
- Inspect the brake pads for even wear; replace if necessary.
Brake Rotors:
- Check the rotor for warping using a dial indicator; if warped, proceed to replace.
- If the rotor is within specifications, consider having it resurfaced.

4. Replace Brake Pads and Rotors (if necessary)

Install new brake pads and ensure they are properly seated in the caliper bracket.
If replacing rotors, remove the old rotor by unscrewing the retaining screws (if applicable), and install the new rotor.
Torque the rotor screws to the manufacturer’s specifications (typically around 10-15 ft-lbs).

5. Reassemble Brake System

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

6. Lower Vehicle and Final Checks

Carefully lower the vehicle back to the ground.
Use the lug wrench to fully tighten the lug nuts in a star pattern to ensure even pressure.
Pump the brake pedal several times to seat the brake pads before driving.
