Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical issues while working on the brakes.

2. Wheel Removal

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle using a hydraulic jack.
Secure the vehicle on jack stands.
Remove the lug nuts completely and take off the wheels.

3. Brake Component Inspection

Tools Required: Torque wrench, brake pad gauge.
Inspect the brake rotors for warping by checking for uneven surfaces.
Measure rotor thickness; if below manufacturer's specifications, replace the rotors.
Check brake pads for wear; replace if they are worn down to the indicators.

4. Rotor Resurfacing or Replacement

If rotors are warped but still within specifications, consider resurfacing them.
If replacing:
- Remove the caliper by unbolting it from the bracket.
- Remove the brake rotor by unbolting it from the hub assembly.
- Install new rotors, ensuring they are torqued to manufacturer specifications (typically around 80-100 ft-lbs).

5. Brake Pad Replacement

Replace brake pads:
- Compress the caliper piston using a C-clamp.
- Install new brake pads into the caliper bracket.
- Reinstall the caliper over the new pads, ensuring proper alignment.

6. Reassembly

Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque (typically around 76 ft-lbs).
Reconnect the battery.
