Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, jack and jack stands, lug wrench, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect: Check the brake pads for wear. If they are less than 3mm thick, they need replacement.
Remove: Use a socket set to unfasten the caliper bolts and carefully slide the caliper off the rotor.
Replace: Remove the old brake pads from the caliper bracket. Install new brake pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect: Check the rotors for any grooves or excessive wear.
Replace: If the rotors are damaged, remove the rotor by unfastening the retaining screws or bolts. Install new rotors in the reverse order.

5. Reassemble Braking System

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications (usually 100-120 ft-lbs).

6. Final Checks

Pump the brake pedal to ensure proper seating of the pads and calipers.
Check brake fluid level again and top off if necessary.
