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. Lift Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts with the appropriate socket.
- Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
- Check the brake pads for wear patterns and thickness.
Replace Pads (if necessary):
- Remove the old pads from the caliper bracket.
- Apply brake grease to the backing of the new pads to prevent noise.
- Install the new pads into the caliper bracket.

5. Inspect and Replace Rotors (if necessary)

Check the rotor surface for grooves or warping.
If replacement is needed, remove the caliper bracket using the socket set.
Slide off the rotor and install a new rotor, ensuring it is properly seated.

6. Reassemble Components

Reattach the caliper over the new pads and secure it with the caliper bolts to the specified torque (typically 25-35 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even pressure.

7. Lower Vehicle

Remove the jack stands and lower the vehicle back to the ground.

8. Test Brake Function

Pump the brake pedal a few times to seat the pads against the rotor.
Check for any unusual noises or issues during the test drive.
