what does it mean if my Toyota Highlander shakes when I brake

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface, engage the parking brake, and ensure the engine is off.
• Wear safety glasses and gloves for protection.

2. Lift the Vehicle

• Use a jack to lift the front of the vehicle.
• Secure the vehicle on jack stands for safety.

3. Remove Wheel and Brake Components

• Use a lug wrench to remove the lug nuts and take off the front wheel.
• Remove the brake caliper using a socket set (typically 14mm or 17mm bolts).
  • Support the caliper with a bungee cord to avoid stress on the brake line.
• Remove the brake pads from the caliper brackets.

4. Inspect and Replace Brake Rotors

• Check the rotor for warping using a dial indicator gauge.
• If warped beyond manufacturer specifications, replace the rotors.
  • Remove the rotor by unscrewing it from the hub (if applicable).
  • Install new rotors and torque to manufacturer specifications (usually around 80-100 ft-lbs).

5. Install New Brake Pads

• Clean the caliper bracket and ensure it is free of rust and debris.
• Apply brake grease to the back of the new pads and install them into the bracket.
• Reattach the caliper over the new pads and torque the caliper bolts to specifications (typically around 25-35 ft-lbs).

6. Reassemble and Test

• Reinstall the wheel and torque the lug nuts in a star pattern to manufacturer specifications (usually around 80-100 ft-lbs).
• Lower the vehicle and perform a test drive to ensure the brakes function properly without shaking.
