Leaky slave and main cylinder with Sachs race pressure plate

[Schlander]

Hi guys

Over the years I’ve always run Sachs race clutch assembly on both 24v swap and the M20 I’m running know. Both setups have the same problem, eventually the slavecylinder and even at times the master gets leaky.

I’ve tried with different brands, OE and still having the same issue.

So I’m looking for what do you use for slave and master cylinders with stronger pressure plates??

I've always thought that the concentric secondary like Saab, Ford and others used was very elegant, as it gets rid
of the linkage at the transmission entirely. The Saab version's too small for the BMW input shaft, which is a shame-
it's hellaciously stout, and uses a couple of o- rings as seals.
I used that with the 7" Quartermaster, and it worked really well.

Beyond that cool story, all I gots...

I run stock slave and master with kevlar clutch, no issues. Are you running over 600hp?

Not at all, only 265hp so i really dont need the Race pressure plate. But I have it so I use it :)

I'm considering changing to a stock clutch to get a lighter feel.

I'm surprised the master and slave are giving up at all though. if they are questionable quality aftermarket items, id look at getting them rebuilt by someone who knows what they are doing. Over the years i have always had my brake and clutch hydraulics rebuilt by a local shop here that makes new stainless pistons and use high quality seals. I'ts not the cheapest option, but i just don't trust new parts these days.

The pressure plate might be heavy duty or whatever, but for a hydraulic system it shouldn't really matter.....
