⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is secure on jack stands before working underneath.
•Allow brakes to cool before inspection to prevent burns.

Symptoms

•Steering wheel vibrates during braking
•Pulsation felt in the brake pedal
•Uneven brake pad wear
•Possible grinding noise when braking
•Vehicle pulls to one side when braking

Diagnostic Steps

1
Inspect brake components for uneven wear or damage.
2
Check brake rotor thickness using a micrometer for warping.
3
Examine suspension and steering components for play or damage.
4
Ensure wheel lug nuts are properly torqued.
5
Scan for any ABS or brake system error codes using an OBD-II scanner.
6
Test drive the vehicle to replicate the shaking and assess severity.

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

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

3. Inspect Brake Components

Brake Pads: Remove the brake caliper using a socket set and inspect the pads for uneven wear.
Rotors: Check the brake rotors for warping. If warped, they must be resurfaced or replaced. Use a micrometer to measure the rotor thickness at several points.
Caliper: Inspect the brake calipers for proper operation and any signs of leakage.

4. Replace Rotors (if necessary)

If the rotors are warped beyond specifications, replace them:
- Remove the old rotor.
- Clean the hub surface where the rotor mounts.
- Install the new rotor, ensuring it is correctly seated.
- Torque the rotor bolts to the manufacturer’s specifications (typically around 80-100 ft-lbs, but check service manual).

5. Replace Brake Pads (if necessary)

If pads show significant wear, replace them:
- Remove old pads from the caliper bracket.
- Compress the caliper piston using a caliper tool.
- Install new pads, ensuring proper alignment and fit.

6. Reassemble and Lower the Vehicle

Reinstall the brake caliper over the new pads.
Reattach the wheel and torque lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).
Lower the vehicle from jack stands.

7. Test Drive

Conduct a test drive to confirm the repair resolved the shaking issue.
