Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
Safety glasses
Gloves

2. Remove Wheel

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 completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts using a socket.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for wear; replace if less than 3mm thick.
- Install new brake pads, ensuring they are oriented correctly.
Brake Rotors:
- Check the rotor surface for grooves or warping.
- If damaged, remove the rotor by unscrewing the retaining screws.
- Install a new rotor, ensuring it is properly seated.

4. Reassemble Braking System

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands.
Torque the lug nuts to manufacturer's specifications (usually around 80-100 ft-lbs).
Pump the brake pedal to ensure proper engagement of the brake pads.
