Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspection: Check the brake pads for wear; if they are below 3mm, they need replacement.
Replacement:
1. Remove the caliper bolts using a socket set.
2. Slide the caliper off the brake rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are properly seated.
5. Compress the caliper piston using a C-clamp to allow space for the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check for scoring, warping, or significant wear on the rotors.
Replacement:
1. Remove the caliper bracket bolts and set the bracket aside.
2. Slide the rotor off the hub. If it is stuck, tap lightly with a rubber mallet.
3. Install the new rotor, ensuring it is properly aligned.
4. Reattach the caliper bracket and torque to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the negative battery terminal.
Test the brakes at low speed to ensure proper operation.
