brake servo noise

Recommended Posts

Upon braking I hear the brake servos work and I expect that. But when I'm on a hill or otherwise need to hold the brake on, the servos continue to "whine" the whole time. I figure they should whine until they fully deploy then stop. Is it "TADT" to whine all the time the brake lever is depressed?

The servos will whine whenever there is a force applied to the lever or pedal. This occurs whether you are moving or stationary. It is completely normal.

I like telling folks that that noise is from the servo motors for the .50 cal "cage" guns............. grin.gif

It took years of R&D for BMW to get the servos to sound exactly like a dental drill. On the bright side, all the design engineers now have great teeth. grin.gif

O.K., yet another "TADT" situation! Thanks once again for the replies, now I can enjoy the ride and not worry....
