my Toyota Highlander shakes when braking what's causing it

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a flat surface and engage the parking brake.
• Disconnect the battery for safety.

2. Remove Wheel

• Use a lug wrench to loosen and remove the wheel lug nuts.
• Safely lift the vehicle using a jack and secure it with jack stands.

3. Inspect and Replace Brake Components

• Inspect Brake Pads:

  • Remove the caliper by unbolting it from its mounting bracket.
  • Inspect brake pads for thickness and replace if worn below specifications.

• Inspect and Resurface/Replace Rotors:

  • Remove the rotor from the wheel hub.
  • Use a micrometer to measure rotor thickness; if warped, resurface or replace as needed.

• Reassemble:

  • Reinstall the rotor and caliper, ensuring all bolts are torqued to manufacturer specifications.
  • Replace wheel and lug nuts, torquing to the appropriate specification.

4. Brake Fluid Check

• Inspect brake fluid level and condition in the reservoir.
• If contaminated, perform a brake fluid flush and replace with the recommended fluid type.

5. Reinstall Wheel and Lower Vehicle

• Reinstall the wheel and lug nuts.
• Lower the vehicle and tighten lug nuts to manufacturer’s torque specifications.
