Why do I get vibration when I brake?
No pulsation or vibration when braking. Since then, I have had the wheels balanced, replaced bad control arm bushings and still have the vibration. Went in today and cleaned the wheel mating surface on the rotor hat. Made no difference. At this point, I am thinking I have a rotor that is not balanced.
How are brake rotors related to wheel speed?
Brake rotors are bolted directly to the wheel hub, so they spin in direct relation to wheel speed. When the brake pedal is depressed, the calipers squeeze the brake pads against the spinning rotors to slow and stop the wheels and the vehicle. Since rotors work to slow the vehicle by using friction from direct contact with the brake pads,…
What causes brakes to shake right after rotor and pad?
The shimmy feeling that comes from brakes is usually due to uneven friction material build-up on the rotor. This transfer from pad to rotor is supposed to happen, indeed it makes the brakes work better, which is why brakes function better after break-in. However when it happens unevenly, it produces a shaking or shimmy feeling.
How can you tell if your brake rotors are bad?
Warped or excessively worn rotors may vibrate irregularly and cause vibrations that can be felt in the pedal, and sometimes through the vehicle’s steering wheel or chassis. Additionally, the brake pedal may feel like it’s pulsating when pressed due to warped brake rotors.

Why does my car’s brake rotor spin when I brake?
Typically of grey iron color (a form of cast iron), the rotor functions to slow/stop the vehicle. It is latched to wheel hub so this rotor spins in the direction of the wheel. When the brake is applied, the spinning rotor slows down the vehicle using friction from direct contact with the pads.
When do you change rotors does the vibration go away?
Starts around 40/45 gets worse through about 60/65, then starts to mellow out, although it doesn’t fully go away. No pulsation or vibration when braking. Since then, I have had the wheels balanced, replaced bad control arm bushings and still have the vibration. Went in today and cleaned the wheel mating surface on the rotor hat.
Why does my car shake when I put the brakes on?
Brake rotors. If your brake rotors have excessive runout — meaning they have a wobble — or they have variations in thickness, this will prevent the brake pads from being parallel to the rotor face. The pads will slip when the brakes are applied.
