why does my Toyota Highlander XU70 (2020-Present) shake when braking

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure vehicle is parked on a level surface and securely lift the vehicle using a jack and jack stands.
• Disconnect the battery if electrical components will be serviced.

2. Inspect and Replace Brake Pads

• Sub-steps:
  1. Remove the wheel using a socket set.
  2. Remove the caliper bolts and carefully slide the caliper off the rotor.
  3. Take out the old brake pads from the caliper bracket.
  4. Compare the thickness of the old pads with new ones; if worn, replace with quality OEM or aftermarket pads.
  5. Apply anti-squeal lubricant to the back of the new pads and reassemble the caliper.

3. Inspect and Resurface or Replace Rotors

• Sub-steps:
  1. Check rotor surface for grooves or discoloration; use a dial indicator to measure runout.
  2. If warped, either resurface rotors using a brake lathe or replace with new rotors.
  3. If replacing, ensure the new rotors are cleaned and properly installed.
  4. Torque the rotor retaining bolts to the manufacturer’s specifications.

4. Inspect Suspension Components

• Sub-steps:
  1. Visually inspect control arms, bushings, and tie rods for any signs of wear or damage.
  2. Replace any worn or damaged components as necessary.
  3. Ensure that all bolts are tightened to the manufacturer's specified torque values.

5. Wheel Alignment and Balancing

• Sub-steps:
  1. After completing the brake and suspension work, take the vehicle to a professional for alignment and balancing.
  2. Confirm that the correct specifications are met for the alignment.

Tools Required:

• Socket set
• Torque wrench
• Brake lathe (if resurfacing rotors)
• OBD-II scanner
• Jack and jack stands

Parts Required:

• Brake pads
• Brake rotors (if replacing)
• Suspension components (if worn)

Estimated Repair Time: 2-4 hours

Safety Warnings:

• Disconnect the battery before working on electrical systems.
• Allow brakes to cool before handling components.
• Always use jack stands when working under the vehicle.
