Diagnostic Steps

1
Inspect brake pads and rotors for wear and warping using a visual inspection.
2
Check for any foreign debris between the brake components.
3
Use a dial indicator to measure rotor runout and determine if they are warped.
4
Inspect suspension components (control arms, tie rods, and bushings) for wear or damage.
5
Check wheel alignment and balance to ensure proper vehicle handling.

Solution

1. Preparation

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

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the wheel is still on the ground.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Check the thickness of brake pads; replace if below manufacturer specifications.
- Measure rotor thickness; replace if worn beyond limits.
Replace Rotors (if warped):
- Remove caliper bolts and slide caliper off the rotor.
- Remove the rotor by unscrewing any securing screws and pulling it off the hub.
- Install new rotor, ensuring it is properly seated.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Compress the caliper piston using a brake caliper tool.
- Install new brake pads into the caliper bracket.

4. Reassemble and Recheck

Reattach the caliper over the new pads and securely fasten caliper bolts to manufacturer torque specifications.
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

5. Test Drive

Conduct a test drive to check for any remaining vibration issues during braking.
