Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts and raise the vehicle using a jack.
Secure the vehicle on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection: Check brake pads for wear. If they are less than 3mm thick or unevenly worn, replace them.
Replacement:
1. Remove the caliper bolts using a socket set.
2. Carefully lift the caliper off the rotor without disconnecting the brake line.
3. Remove the old brake pads.
4. Install new brake pads, ensuring they are seated correctly.
5. Reattach the caliper and torque the bolts to the manufacturer's specifications (typically 25-35 ft-lbs for caliper bolts).

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check rotors for any signs of damage, warping, or excessive wear.
Replacement (if needed):
1. Remove the caliper (as described in the previous step).
2. Remove the rotor retaining screws if present.
3. Slide the rotor off the hub.
4. Install the new rotor, ensuring it fits snugly onto the hub.
5. Reinstall the caliper.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
Test the brake system by pressing the pedal several times to seat the pads.
