Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel bolts.
Take off the wheel and set it aside.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are worn down to 3mm or less, they need replacement.
Replacement:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads ensuring they fit securely in place.
5. Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specification (typically around 20-25 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped:
1. Remove the caliper bracket bolts and take off the bracket.
2. Slide off the rotor.
3. Replace with a new rotor or have the existing rotor resurfaced if within service limits.
4. Reinstall the caliper bracket and torque bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug bolts.
Lower the vehicle to the ground and torque the wheel bolts to the manufacturer’s specifications (typically around 76-83 ft-lbs).
Test the brake system by pressing the brake pedal to ensure proper engagement.
