Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked 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 the lug nuts.
Remove the lug nuts completely and take off the wheel.
Tools required: Lug wrench, jack, jack stands.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts; use a socket set for this.
Carefully slide the caliper off the rotor and support it without straining the brake line.
Remove the old brake pads from the caliper bracket.
Replace with new brake pads ensuring they are properly aligned and seated.
Tools required: Socket set, brake pad spreader.

4. Inspect and Resurface/Replace Rotors

Check the rotors for grooves or warping.
If they are within specifications, resurface them using a brake lathe; if not, replace them.
Install the rotors back onto the hub, ensuring they are properly seated.
Tools required: Brake lathe (if resurfacing), replacement rotors (if necessary).

5. Reassemble Brake Components

Re-install the caliper over the new brake pads and secure it with the caliper bolts; torque to manufacturer specifications (usually around 20-25 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle and tighten the lug nuts in a star pattern to ensure even pressure.
Start the vehicle and pump the brakes to ensure proper function before taking a test drive.
