I own a 1997 v6 camaro. I was looking into swapping my rear end (with drum brakes) to that of a z28 or SS (with disks). Would I have to put a booster on my master cylinder or also swap it out to account for the disk brakes? Oh, and thanks ahead of time Stan

 

Haha. No, you won't need to change any of that. E-brake cables are different, so I would make sure to grab them off of the car you get the rear from. Or just get some new ones.

 

Yea, but wouldn't disk brakes require more pressure? So the master cylnider on base coupes and SS's are exactly the same? How can this be when the SS's have disks all the way around?

 

Time and money saving was what GM had in mind when they did that. But yes they are the same. Your front brakes are what take all the beating and use most of the power of your master cylinder anyhow.

 

i thought the proportioning valve was different?

 

I have never heard of anyone talking about that in their writeups, and I could swear someone on here looked it up one time, and they were the same. I could be wrong, but nothing I have seen or read would lead me to believe otherwise.

 

i guess one could look up part #'s

 

now that i think about it, i think the proportioning valve is built into the ABS block, so i doubt gm made two different abs units.

 

When I was at Vale tech my teacher hammered it into us that any change in the brake system required a different combination valve. Even a change in the ride height. If its not a stock setup then you had to put an ajustable one in. I was sure they would be different. Until I looked them up. It all the same part numbers. I guess it because the computer is monitoring wheel speed it makes the hardware more "forgiving" for lack of a better word.
