why does my Toyota Highlander Fourth Generation (2020-present) shake when I brake

Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

• Remove the Wheel: Use a jack to lift the vehicle and secure it with jack stands. Remove the lug nuts using a socket set.
• Inspect Pads: Check brake pads for thickness and any uneven wear. If worn beyond specifications (usually 3mm or less), replace them.
• Install New Pads: Remove old pads and install new ones, ensuring proper alignment. Torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Inspect and Resurface/Replace Rotors

• Remove Caliper: Unscrew caliper mounting bolts and carefully lift the caliper off the rotor.
• Check Rotor Condition: Use a runout gauge to measure rotor thickness. If warped (exceeding 0.002 inches), either resurface or replace the rotor.
• Install Rotor: If replacing, install the new rotor and ensure it is correctly aligned. Reinstall the caliper and torque bolts to specifications.

4. Suspension Component Check

• Visual Inspection: Check control arms, bushings, and tie rods for any visible signs of wear or damage.
• Replace Components as Needed: If any parts are worn, replace them following manufacturer specifications. Use a torque wrench to secure new parts to the appropriate torque values.
