Which Mastercylinder with Hydaboost??

[Steve68]

I have my new Hydraboost system, C5 brakes Front and rear, which master should I use, Ihave the one that originally came with the car or a brand new Mopar aluminumn, or mid 80's Vette, I have to see what fits but I'd thought I throw this out, thanks Steve

Guess who would know the answer to that the best? That's right, the people who make the parts you're asking about. Call Paul@Hydratech.

Well I thought I'd ask here too, I know I can't be the only person on this board using his setup, but I guess I ask the guy who makes it, maybe someone here might have had experiences with something different!

I would definitely give Paul a call.He is totally cool and will steer you in the right direction. For me, I used a 2004 GMC Sierra hydroboost and kept that master cylinder. Mine works excellent.

With my Hydroboost I used a 77-81 Corvette MC. It was recommended by the company for my application. Bore size is the major determinig factor.
