my Honda Accord shakes when I brake, what could be causing this?

Solution

1. Preparation

• Gather tools and parts before starting. Ensure vehicle is parked on a flat surface.
• Tools required: jack, jack stands, lug wrench, micrometer, brake cleaner, and torque wrench.
• Safety warnings: Ensure the vehicle is in "Park" or in gear and the parking brake is engaged.

2. Remove Wheel

• Use the lug wrench to loosen lug nuts on the affected wheel.
• Raise the vehicle with a jack and support it with jack stands.
• Remove the wheel to access the brake components.

3. Inspect and Replace Brake Components

• Inspect Brake Rotors:
  • Measure the rotor thickness using a micrometer. If warped (greater than 0.002 inches), resurface or replace.
• Inspect Brake Pads:
  • Check for uneven wear. Replace if less than 3mm thickness remains.
• Inspect Brake Calipers:
  • Ensure calipers are functioning correctly and not sticking. Replace if necessary.
• Replace Components:
  • If rotors or pads are worn or damaged, replace them with OEM or quality aftermarket parts, following manufacturer specifications.

4. Reassemble and Torque

• Reattach the wheel and hand-tighten the lug nuts.
• Lower the vehicle and use a torque wrench to tighten the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs for Honda).

5. Test Brake System

• Start the vehicle and pump the brakes to ensure proper function.
• Conduct a test drive in a safe area to confirm the issue has been resolved.
