my Toyota Highlander shakes when braking what could be causing this

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Remove Wheel

• Use a lug wrench to loosen the lug nuts of the affected wheel.
• Lift the vehicle using a jack and secure it with jack stands.
• Remove the wheel completely.

3. Inspect and Replace Brake Rotors

• Inspect Rotors: Check for signs of warping or scoring. If damaged, replace.
• Remove Caliper: Unbolt the brake caliper using a socket wrench and secure it with a bungee cord to avoid straining the brake line.
• Remove Rotor: Unscrew the retaining screws (if applicable) and slide the rotor off the hub.
• Install New Rotor: Place the new rotor onto the hub and secure it with screws.

4. Inspect and Replace Brake Pads

• Remove Old Pads: Take out the old brake pads from the caliper bracket.
• Install New Pads: Apply brake grease to the back of the new pads and insert them into the caliper bracket.

5. Reassemble and Test

• Reattach Caliper: Position the caliper over the new pads and bolt it back in place.
• Reinstall Wheel: Place the wheel back on and hand-tighten the lug nuts.
• Lower Vehicle: Remove jack stands and lower the vehicle to the ground.
• Torque Lug Nuts: Use a torque wrench to tighten lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
