Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely lifted before working underneath.
•Allow the brakes to cool before touching any components after driving.

Symptoms

•Steering wheel shakes or vibrates during braking
•Pulsating brake pedal feel
•Vehicle pulls to one side when braking
•Increased stopping distance
•Unusual noise from brake components (e.g., grinding or squeaking)

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and even wear; replace if worn unevenly.
3
Examine suspension components (e.g., control arms, bushings) for wear or damage.
4
Verify wheel alignment and balance; check for any bent wheels.
5
Scan for any error codes related to the ABS system, which may indicate issues.

Solution

1. Preparation

Gather tools and materials needed.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts (if ABS components are involved).

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, dial indicator, jack stands
Remove the wheel using a socket set.
Inspect the brake rotor using a dial indicator to measure runout; if it exceeds specifications (typically 0.002 inches), replace the rotor.
If replacing, remove the caliper by unbolting it, and hang it with a bungee cord to avoid straining the brake line.
Remove the rotor by unscrewing it from the hub.
Clean the new rotor with brake cleaner to remove any protective coating.
Install the new rotor and torque to manufacturer specifications (usually around 70-90 ft-lbs).

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; replace if they are less than 3mm thick.
Remove the caliper bracket bolts and pull the caliper off the rotor.
Replace the old pads with new ones, ensuring they are seated correctly.
Reassemble the caliper and torque the bolts to the specified value.

4. Suspension Component Inspection

Inspect control arms, ball joints, and bushings for wear.
If any components are damaged, replace them to ensure proper alignment and handling.

5. Wheel Alignment and Balancing

After completing brake and suspension repairs, have the wheels aligned and balanced by a professional to ensure proper handling and prevent future shaking.
