2
Check brake pads for uneven wear and proper thickness.
3
Examine suspension components for damage or wear (e.g., control arms, bushings).
4
Verify wheel alignment and balance.
5

Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear gloves and safety glasses.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the issue originates.
Secure with jack stands for safety.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake components.

4. Inspect and Replace Brake Rotors

Inspect Rotors: Check for warping using a dial indicator.
Replace Rotors:
1. If warped beyond specifications, remove the caliper by unbolting it and hanging it with a wire.
2. Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
3. Install the new rotor, ensuring it is seated properly.
4. Torque the retaining screws to manufacturer specifications (typically around 10-15 lb-ft).

5. Inspect and Replace Brake Pads

Inspect Pads: Check for uneven wear and thickness.
Replace Pads:
1. If worn below specifications, remove the caliper bracket and pads.
2. Clean the caliper bracket and apply brake grease to the sliding surfaces.
3. Install new brake pads in the bracket.
4. Reinstall the caliper over the pads and torque bolts to specifications (typically 25-35 lb-ft).

6. Reassemble Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications (typically 75-85 lb-ft).

7. Test Brake System

Pump the brake pedal to ensure proper caliper engagement before driving.
