For those with CM30, does this happen to your car???

I had my CM30 installed last week, felt minor vibrations from the brake paddle. I didn't know what caused it at that time.

I found it today that it was the CM30 that caused it. After I shut the engine off, the vibrations are still there, in 5-10 seconds, it's completely gone.

Is this normal or something needs to be fixed?

Thanks everyone.

I had the connector cut and wired it together, so it is plug-less

Thanks, i planned install the CM90 but eventually the CM30. The CM90 pumps much more liquid, is the system capable of handling with the massive flow?

unless your CM30 pump was not installed correctly, there should be no vibrations coming from the pump, i would check to make sure that the pump is securely bolted to the mounting bracket...
