•Allow the vehicle to cool down before working on brake components.

Symptoms

•Steering wheel shakes when braking
•Pulsation felt through the brake pedal
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Potential noise from brakes (squealing or grinding)

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pad thickness for wear and replace if below manufacturer's specifications.
3
Examine wheel lug nut torque to ensure they are properly tightened.
4
Inspect suspension components (e.g., control arms, bushings) for wear or damage.
5
Test drive the vehicle to replicate shaking and assess severity.

Solution

1. Preparation

Gather necessary tools and materials.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts slightly while the wheel is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Rotors

Inspection: Use a dial indicator to measure rotor runout. If it exceeds manufacturer specifications, proceed with replacement.
Removal: Remove caliper bolts and lift the caliper off the rotor, secure it with a wire or bungee cord to avoid stress on the brake line.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Replacement: Install the new rotor and ensure it is seated correctly. Reinstall any retaining screws.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of leakage or damage.
Install new brake pads, ensuring they are properly aligned in the caliper bracket.

5. Reassemble and Test

Reinstall the brake caliper over the new pads and tighten caliper bolts to the manufacturer's torque specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque.
Test drive the vehicle to ensure the shaking is resolved.
