Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electronic components.
•Ensure the vehicle is securely supported on jack stands before working underneath it.

Symptoms

•Steering wheel shakes or vibrates during braking
•Vehicle shakes at specific speeds, particularly noticeable when slowing down
•Increased brake pedal pulsation or vibration
•Uneven brake pad wear or scoring on brake rotors
•Possible noise from the brakes, such as squealing or grinding

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a runout gauge.
2
Check brake pad thickness and condition for even wear.
3
Examine suspension components, including control arms and bushings, for wear or damage.
4
Inspect wheel alignment and balance to rule out any issues contributing to shaking.
5
Scan for any brake system-related fault codes using an OBD-II scanner.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
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 and Replace Brake Rotors

Inspect Rotors: Measure the rotor thickness using a micrometer; ensure it meets manufacturer specifications.
Replace Rotors:
1. Remove the caliper by unscrewing the caliper bolts with a socket set.
2. Carefully hang the caliper using a wire or bungee cord to avoid straining the brake line.
3. Remove the old rotor from the hub by unscrewing any retaining screws or clips.
4. Install the new rotor onto the hub, ensuring it is seated properly.
5. Reinstall the caliper and torque caliper bolts to manufacturer specifications (usually around 30 Nm).

4. Check and Replace Brake Pads

Inspect Pads: Check for uneven wear or damage.
Replace Pads:
1. Remove the old brake pads from the caliper bracket.
2. Compress the caliper piston using a brake caliper tool to make space for the new pads.
3. Install the new pads into the caliper bracket.
4. Ensure the anti-rattle clips are properly positioned.

5. Reassemble and Lower the Vehicle

Reinstall the front wheels and torque lug nuts to manufacturer specifications (typically 120 Nm).
Lower the vehicle and remove the jack stands.
Perform a final inspection of all components to ensure proper assembly.
