Ensure the vehicle is parked on a flat surface, and apply the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

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

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Check for warping using a dial indicator.
If warped, proceed to replace the rotors.

B. Remove Brake Caliper

Tools Required: Socket set, torque wrench.
Unbolt the caliper from the bracket.
Secure the caliper with a bungee cord or similar to avoid straining the brake line.

4. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Torque caliper bolts to manufacturer specifications (usually around 25-30 Nm).
Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even seating.

5. Lower Vehicle and Test Brakes

Lower the vehicle back to the ground.
Pump the brake pedal to ensure the pads are seated correctly.
