Re: typ44TQ brake question

Jordan,

When the fan is running after you shut the car off,  just touch the electric pump
( watch the fan blade ) to feel for vibration.  They are not audible above the
noise of the fan.  I have 2 Audi's.  One is an '88 with the original pump still
working and the other an '86 that I just replaced.  That is a pretty long lifespan
although I agree the design is poor.  I suppose it depends on your climate.  Here
is Minnesota those pumps hardly run between September and May.
