Solution

1. Preparation

Gather Tools and Parts:
- Tools: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a dial caliper.
- Parts: New brake pads, new rotors (if needed), and brake lubricant.
Safety Warnings:
- Ensure the vehicle is on a flat surface and secured with jack stands.
- Disconnect the vehicle's battery to prevent any electrical issues during brake work.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Remove Brake Components

Visually inspect the brake pads for wear; if less than 3mm thick, replace them.
Remove the caliper by unbolting it from the bracket using the socket set.
Slide the caliper off the rotor and support it using a bungee cord (do not let it hang on the brake line).
Remove the brake pads from the caliper bracket.

4. Replace Brake Pads and Rotors

If rotors are damaged, remove them by unbolting from the hub.
Clean the new rotors with brake cleaner to remove any protective oil.
Install new rotors onto the hub, ensuring they are seated properly.
Apply brake lubricant to the back of the new brake pads and install them into the caliper bracket.

5. Reinstall Caliper and Wheel

Reposition the caliper over the new brake pads and secure it with the bolts, tightening to the manufacturer’s torque specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications (usually 75-90 ft-lbs).

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to ensure proper seating of the pads.
Test brake functionality by performing a short drive to check for noise and effectiveness.
