my Toyota Corolla E170 (2013-2019) shakes when I brake, what’s causing it

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the battery to prevent any electrical issues.

2. Lift the Vehicle

• Use a jack to lift the front of the vehicle and secure it with jack stands.
• Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Components

A. Brake Rotors

• Sub-steps:
  1. Remove the caliper mounting bolts using a socket set.
  2. Carefully slide the caliper off the rotor and secure it without straining the brake line.
  3. Remove the rotor by unscrewing any retaining screws, if applicable.
  4. Measure rotor thickness with a micrometer; if below specifications or warped, replace.
  5. Install new rotors, ensuring proper orientation and tightening retaining screws if applicable to manufacturer's torque specifications.

B. Brake Pads

• Sub-steps:
  1. Remove old brake pads from the caliper bracket.
  2. Inspect the caliper bracket for debris and clean as necessary.
  3. Install new brake pads, ensuring proper fitment and alignment.
  4. Lubricate brake pad contact points with high-temperature brake grease.

4. Reassemble and Lower Vehicle

• Reattach the brake caliper over the new pads and rotor.
• Tighten the caliper mounting bolts to manufacturer specifications.
• Reinstall the wheels and hand-tighten lug nuts.
• Lower the vehicle and torque the lug nuts to specification.

5. Test the Brake System

• Reconnect the battery.
• Pump the brake pedal to seat the pads against the rotors.
• Conduct a test drive to ensure proper brake function and check for any vibrations.
