my Toyota Highlander shakes when I brake what should I do

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery if working on electrical components.

2. Remove Wheel

• Loosen the lug nuts with a socket set.
• Elevate the vehicle using a jack and secure it with jack stands.
• Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

• Remove the caliper bolts using a socket wrench.
• Carefully slide the caliper off the rotor and support it without straining the brake line.
• Remove the old brake pads from the caliper bracket.
• Inspect the caliper slides and clean if necessary.
• Install new brake pads, ensuring any anti-squeal shims are used.

4. Inspect and Resurface or Replace Rotors

• Check the rotor for warping using a dial indicator gauge.
• If warped, either resurface the rotor using a brake lathe or replace it with a new rotor.
• Clean the rotor surface with brake cleaner before installation.

5. Reassemble Components

• Slide the caliper back over the new brake pads and rotor.
• Reinstall the caliper bolts and tighten to manufacturer specifications (typically around 20-30 ft-lbs).
• Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

• Lower the vehicle off the jack stands and remove the jack.
• Tighten the lug nuts to the specified torque (usually 75-85 ft-lbs).
• Reconnect the battery.
• Perform a test drive to ensure proper brake function and check for any vibrations.
