Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and place jack stands for safety.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Check the brake pads for wear indicators; replace if below specification.
To remove the brake pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a wire or bungee cord (do not let it hang).
- Remove the old brake pads from the caliper bracket.
Install new brake pads:
- Apply brake grease to the back of the new pads (if required).
- Slide the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for any scoring or warping.
If replacement is needed:
- Remove the rotor by unbolting it from the hub (if it’s not stuck).
- Install the new rotor and torque the bolts to manufacturer specifications.

5. Reassemble and Test

Reattach the caliper over the new brake pads and torque caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque.
Pump the brake pedal several times to ensure proper pad seating and brake fluid flow.
