Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Check the brake rotors for warping using a dial indicator; replace if they exceed manufacturer specifications (typically over 0.002 inches of runout).
If replacing, remove the caliper by loosening the caliper bolts with a socket set.
- Tools Required: Socket set, torque wrench
Remove the rotor by unscrewing the retaining screws if present.
Install new rotors, ensuring they are properly seated.
Torque the rotor retaining screws to the manufacturer’s specification (usually around 10-15 Nm).

4. Check and Replace Brake Pads

Inspect brake pads for wear; replace if they are less than 3mm thick.
Remove the caliper bracket using a socket set and replace the pads.
- Tools Required: Torque wrench
Apply anti-squeal lubricant to the back of the new pads for smoother operation.
Reinstall the caliper and torque the caliper bolts to manufacturer specifications (typically around 30-35 Nm).

5. Inspect Suspension Components

Visually check the ball joints and tie rods for play or damage; replace any defective parts.
If necessary, use a ball joint separator tool for removal.

6. Wheel Alignment and Balance

After reassembling, take the vehicle to a professional for wheel alignment and balance to prevent uneven tire wear.
