Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheels using a socket wrench.

3. Inspect and Replace Brake Components

A. Brake Rotors

Inspect: Check the rotors for warping using a dial indicator gauge.
Replace: If warped, remove the caliper (unbolt caliper brackets) and the rotor (remove retaining screws if present).
Install: New rotor must be torqued to manufacturer specifications.

B. Brake Pads

Inspect: Check thickness of the pads. Replace if worn below the manufacturer's minimum thickness.
Replace: Remove old pads from caliper bracket. Install new pads ensuring correct orientation.

4. Caliper Inspection

Check: Inspect calipers for any signs of sticking; clean slide pins and apply brake grease if necessary.
Replace: If calipers are faulty, unbolt and replace with new units, ensuring proper torque is applied.

5. Reassemble and Lower the Vehicle

Reattach wheels and torque lug nuts to specification.
Lower the vehicle from jack stands and remove jack.
