Zipty makes a slave body and 7602 racing makes a better slave piston. I guess you could get a brembo master like the newer models went to in 2011 I believe.
I will give my 0.02 on the matter as I have had extensive negative experience with my 09' TE310...
Firstly, the stock components: While they seem like junk, are at least meant to function together. I had bought a new ZT slave and 7602 piston, and while each of these components may function perfect fine with their stock counterpart, they do not seem to work well together. Now, I did not have a stock piston or cylinder to test this theory out, but ill explain further on that shortly. I think the issue is mostly due to a tolerance discrepancy, not poor design intent.
Now, I am not point fingers here but I will say that they did seem to point the finger at each other. I even had 7602 tell me flat out that they have had other customers calling up with complaints of piston failure and when asked, said that they were using in combination with the ZT cylinder.
I became so frustrated with the whole thing after replacing the seal twice that eventually that took everything out and when with an Oberon slave and piston set. This way, I had a guaranteed fitment between piston and slave...much like stock components.
And yet....
The Oberon slave uses a paper gasket to seal against the engine while the ZT and stock cylinder seems to use an O-ring (much better IMO). Now, these are not supposed to be a high pressure seal, but their is oil cavities pumping oil past that slave...and yep, the Oberon paper filter just couldn't handle it...or at least couldn't handle it on mine. It leaked engine oil...more or less a drip, but leaking non the less and I just wasn't okay with that.
I eventually wound up using some anaerobic sealant between the gasket and sealing surfaces and eventually got it to stop leaking engine oil....all is well for the past year or so. However, if I ever need to take that slave off again, I will most certainly have to clean and re-apply that sealant....
SO, if you are going to replace either slave or master....I would take my experience into consideration before mixing and matching components.
Just my experience...take it with a grain of salt.
