Hi all,

As some of you may recall, I had a brake problem about a week ago that I could not figure out. Problem was that I could not get the pedal to stop sinking once the car was running. I had replaced all the brakes and flushed the system. I even replaced the MC. We bled the system several times in the order advised in the Haynes manual. The brakes felt normal after the bleeding the system with the car off ... but as soon as I turned the car on the pedal started to slowly sink under pressure. I checked all the lines (recently replaced) and no leaks were found. While all this was going on, the brake failure light would come on once and a while. I took apart and reset the switch, but the light came on after the next press of the pedal.

As a last ditch effort (before my 1 week camping trip) I decided to take the brake booster out of my 1986 245 DL and put it into my 1983 242 ti (the one with the problems above). To my delight this solved the problem of the pedal sinking to the floor when the car was turned on. I took the car camping with a full load and it worked great.

I did not reset the brake failure switch and as a result the light still turns on once and a while but the brakes seem to be consistent. Maybe I'll reset the switch tonight.

Thanks for all the help, it was greatly appreciated.

Sincerely,

Greg
