Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Disconnect the battery before working on electrical components.

2. Lift the Vehicle

Use a floor jack to lift the front of the vehicle and secure it with jack stands.
Tools required: Floor jack, jack stands.

3. Remove Wheels

Use a socket set to remove the lug nuts and take off the front wheels.
Tools required: Socket set.

4. Inspect Brake Components

Brake Rotors:
- Measure rotor thickness; if below minimum specifications, replace.
- Check for warping using a dial indicator; replace if warped.
Brake Pads:
- Inspect for wear; replace if pads are below the recommended thickness.
- Ensure pads are installed evenly and correctly.
Suspension Components:
- Inspect control arms, bushings, and tie rods for wear or damage; replace as needed.

5. Replace Components (if necessary)

Rotors:
- Remove old rotors and install new ones, ensuring they are torqued to manufacturer specifications (typically 70-90 ft-lbs).
Brake Pads:
- Install new pads, ensuring they are correctly oriented and seated.
- Tools required: Torque wrench, brake cleaner.

6. Reassemble and Lower Vehicle

Reinstall wheels, hand-tighten lug nuts, lower the vehicle, and then torque lug nuts to manufacturer specifications (typically 100-150 ft-lbs).
Tools required: Torque wrench.

7. Test Brake System

Reconnect the battery.
Pump the brake pedal to ensure proper pressure before test driving.
