Brakes Pulsating

Q: Why does my brake pedal pulsate while applying the brakes?

A: Under heavy braking, you might feel the ABS (Antilock Braking System) working. If you are getting a pulsation under normal braking, your wheel lug nuts may be unevenly tightened. Lug nuts should be evenly tightened using a torque wrench. Look in the owner’s manual for lug nut torque specifications. If you are still getting a pulsation, the brake rotor may be warped. A qualified technician can use a tool called a dial indicator to identify if a brake rotor is warped.
