Master Cyl Size??? - Lateral-g Forums

I have my new C6 brakes in their boxes awaiting their turn to be installed on the car. Meanwhile, i'm cleaning stuff and finishing the tubs etc.

I'm looking at some master cylinders to replace my old and rusty original unit but am now puzzled as to what i should run...I'm thinking a 7/8" but would like opinions. I REALLY like Wilwoods aluminum (polished) unit but for now all i like about it is its looks.

I searched in the forums and could not come up with the info i need. I want to do the right move.

Hydroboost is also in my mind. I've checked a few systems at abspowerbrake.com and hydratech. Just not sure on which master to use and everybody is closed for the holidays!!!

Help!

All those formulas should get you in the ball park. Actually right on the money! Good find Lead!

Yeah....But what a pita!

If someone has an idea still. Be my guest!

I've sent a few e-mails around and will see what the manufacturers reccommend. I love ABS's black chrome unit (Hydroboost) but still need to find out what i need to make this work. My car isn't ps equipped either so i need a ps pump and bracketry too. I want to run an electric w/pump and a low mount alt.

Just a few details i'm taking care of.

I'm running a 1.12 in Wilwood master (part# 260-8556) with a Hydroboost.
6 piston and 4 piston Wilwoods. This is per Paul at Hydratech. I would think that would work for you if you run the hydro.

Those 6 piston Z06 calipers have an awful lot of piston sweep area to move with stock manual brakes. You may have to use a 7/8" or 15/16" master cyl. in order to be able to lock them up but your pedal travel is going to be excessive. I think you`re on the right track with the hydraboost. You`ll get better performance without having to get that "Legs Of Steel" excercise video.
