Hello everyone
On a snowy canadian night, I just put back the braking system on my 73 914. While filling the brake fluid reservoir and pumping the brake pedal I noticed brake fluid coming out of the master cylinder at the brake pedal.

Anything I can do to solve this problem without having to drain the system?

hm, probably no way to fix that without removing the mc. which sucks, because that's my personal least favorite job (so far) on these cars.

sounds like you get to spend another snowy canadian night installing a new master cylinder

Should I change it or rebuild it. Are they rebuildable???

Not too bad to remove at this point for "honey" is still on the rotisserie.

If it were my car I would change it.

One reason the MC starts leaking when you do a bleed is that you get deposits in the MC bore. where the pedal usually stops, when you bleed your pushing the o-rings past these deposits tearing the o-rings.

The MC has been removed from the car and sitting on a shelf, dry, for the past 12 years. I guess that explains the leak.

I have another one stillm installed on my parts car. I guess I`ll try that one

Rebuild your pedal cluster now as well. I've rebuilt a few M/C's no problems, fairly easy job.

Sounds like you've got it figured out...

Last question,

Where can I get a rebuild kit?

If it were me, I'd buy a new one since the m/c is sort of the pivotal main part of the braking system and it is nice to know it is perfect.

I've rblt 2 914 m/c. 1 worked great for years despite the fact it was not an ATE kit and I could only use half the parts. The next one worked great for exactly 1 day and failed at a very inopportune time. Got home, took it apart. Nothing wrong. Put it back, no workie. Never again. I wont cheap out with brakes anymore.

Yeah WTH I`ll go with a new one. You guys are right.

Thanks for all the advises.

Long life to the 914 club
What makes this club so great is the people.
