why does my Honda Civic shake when I brake?

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.

2. Raise the Vehicle

• Use a jack to lift the front or rear of the vehicle, depending on where the shaking occurs.
• Secure with jack stands for safety.

3. Remove Wheel

• Use a lug wrench to loosen and remove the lug nuts.
• Take off the wheel to access the brake components.

4. Inspect Brake Components

• Rotors: Check for warping using a run-out gauge. If warped beyond specifications (usually 0.002 inches), replace the rotors.
• Brake Pads: Inspect for thickness; replace if below manufacturer specifications (usually 3mm or less).
• Calipers: Ensure calipers are functioning correctly and not sticking. If they are seized, replace the calipers.

5. Replace Rotors and Pads (if necessary)

• Rotors:

  • Remove the old rotor by unbolting it from the hub.
  • Install the new rotor, ensuring it is properly aligned and secured.
  • Torque the rotor bolts to manufacturer specifications (typically 85-100 lb-ft).

• Brake Pads:

  • Remove old pads from the caliper bracket.
  • Install new pads, ensuring they are correctly positioned.
  • Lubricate the backing plates with brake grease to prevent noise.

6. Reassemble and Lower Vehicle

• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle and then torque the lug nuts to manufacturer specifications (usually 80-100 lb-ft).

7. Test Brake System

• Pump the brake pedal to seat the pads against the rotor.
• Perform a test drive to ensure that shaking is resolved.
