Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety goggles and gloves.

2. Remove Wheel

Tools: Jack and jack stands, lug wrench.
Loosen lug nuts slightly before lifting the vehicle.
Jack up the vehicle securely and place jack stands under the frame.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Remove Brake Components

Tools: Socket set, torque wrench.
Remove the caliper bolts and carefully slide the caliper off the rotor. Support it using a bungee cord to avoid stressing the brake line.
Remove the brake pads; check for uneven wear or damage.
If necessary, remove the rotor by removing the rotor retaining screws and sliding it off the hub.

4. Replace Worn Components

If brake pads are worn, replace them with new ones. Ensure you use OEM or high-quality aftermarket pads.
If the rotor is damaged or below minimum thickness, replace it with a new rotor. Always replace rotors in pairs for optimal performance.

5. Reassemble Components

Reinstall the rotor (if replaced) and secure with retaining screws.
Slide the new brake pads into place in the caliper bracket.
Reposition the caliper over the pads and secure with caliper bolts. Torque to manufacturer specifications (consult service manual for specific torque values).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts in a criss-cross pattern to the specified torque.
Test the brake pedal for firmness before driving.
