⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery when working on the brake system.
•Allow brakes to cool before inspecting or replacing components.

Symptoms

•Steering wheel shakes during braking
•Vibration felt in the brake pedal
•Increased stopping distance
•Uneven wear on brake pads or rotors
•Possible noise (squeaking or grinding) when braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a rotor gauge.
2
Check brake pads for thickness and any signs of wear or damage.
3
Examine wheel lug nut torque to ensure they are properly tightened.
4
Inspect suspension components (e.g., control arms, tie rods) for play or damage.
5
Perform a road test to assess the severity and conditions under which the shaking occurs.

Solution

Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use wheel chocks to prevent movement.

2. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, brake rotor gauge, socket set, jack and jack stands.
Sub-steps:
1. Loosen the lug nuts on the affected wheel.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the wheel to access the brake assembly.
4. Use the rotor gauge to check for warping; replace if excessive.
5. Remove the caliper by unbolting it and support it with a hanger.
6. Remove the old rotor by unscrewing the retaining screws (if applicable).
7. Clean the hub surface before installing the new rotor.
8. Install the new rotor, ensuring it sits flush against the hub.
9. Reinstall the caliper and torque the bolts to the manufacturer’s specifications.

3. Inspect and Replace Brake Pads

Sub-steps:
1. While the caliper is removed, inspect the brake pads for wear.
2. If they are worn below the minimum thickness, remove them.
3. Install new brake pads, ensuring they are correctly oriented.
4. Reassemble the caliper over the new pads, making sure to compress the piston if needed.

4. Torque the Wheel Lug Nuts

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
