I am doing a SFA on my 97 Chevy K1500. I need some help with a new master cylinder. I need to find one that will work with vacume boost and pushes more fluid and that isn't designed to work with low drag calipers. Anybody have any solution to this problem? Also anybody have any idea how hard it would be to set up a T-case e-brake instead of using those darned eldorado calipers?

ideas anyone?

Ok so a K5 MC would get rid of the low drag caliper part of it right? But then I still need to puchmore fluid. Would a 3500HD unit work? Im not usre if they used hydroboost or not, I know the 3500's did. What about the K30, hydroboost or not?

Not all 3500s have hydroboost. My 89 is a 1 ton and that doesn't have it, and that has a D60 in front, and that stops ok. My 97 has hydroboost, not yet a D60, and that works good too. So I would get a M/C for a 97 3500 with a 454 and hydroboost. High Angle Driveline sells transfer case mounted e-brakes.

So get a MC from a hydroboost truck and switch over to hydroboost? I do know about the HAD driveline brakes...just expensive and integrated into the rear driveshaft.

Going to the hydro master on a vacuum booster would give you almost 0 power to your brakes. It's an 1 5/16s bore. The bigger the bore the more pressure it takes to activate your brakes. I'd just go with the 77-82 Corvette m/c. It's a complete bolt in and replace. If you go the Hydro master you would need to go with the hydroboost also. Your original m/c should be 1 inch (90% sure) and the corvette is 1 1/8. Any bigger and it'll be to hard to stop. This master doesn't put any pressure to your calipers, I think that's what you're asking.

Any questions or if you want more info call 800-256-6295 and ask for Van

My current MC has a quick take up valve that works with low drag calipers which pulls the calipers back from the rotor. Only older calipers don't have this abiity so they will make contact all the time. My current thinking is to keep the rear drums for the e-brake and just get a vacume boost K30 MC that will work perfect with my chevy 60 and 14FF combo.

I understand that using a hydroboost MC with a vacume boost system would result in almost no braking force, when I said convert I meant switch MC, brake booster and power steering pump.
