I am planing on doing a rear disc conversions but however i do not yet have anything but the master cylinder, and booster out of the Teg...I am saving my money to get the rear trailing arms and everything else.. however thats beside the point... I was wondering if i could install the new MC and Break Booster with my stock porp. valve, and stock rear drums... and will it work..? i am not nessicarily looking for any breaking advancements.. i just have time and thought i would do this while i can to reduce the amount of time to do the whole swap..? i dont care if my car will stop any better... however if its going to make it worse then ill forget about it and just wait.... Thanks TJ

 

It should work. It'll just make your brake pedal more firmer because the new mc is bigger than your stock. Once you get the rear discs you should get the appropriate prop valve though.

 

Who told you that you need a new master cylinder & brake booster with a rear disc conversion?

That is totaly un-true. The only thing you need to match a rear disc conversion is the proper proportioning valve (I know because I've done it). The only reason people get a mushy pedal after a rear disc swap, is because they didn't bleed their brakes properly. All 92-95 Civic Si (without ABS) have small 9.5" front brakes with rear discs, but still have the same 13/16" master cylinder as any other "9.4 inch front disc w/ rear drum" civic. The only time you need to upgrade your master cylinder is if you switch to larger front calipers...

What year/model civic do you have?

 

93 DX coupe... i got the MC and booster for real cheap anyways...

 

Honestly, I would suggest selling the booster & MC on ebay. You would probably be better off (unless your planning on an integra front brake swap in the future)...
