while in the middle of my 65 chevelle frame off resto, I bought a 69 olds cutlass for daily driver. I am told it is an A body car so I assume it must be just like a 69 chevelle. It has power drum brakes now. If I get the correct spindles, calipers, etc, can I use the master cylinder and power booster that is currently on the car with the drum brakes? Or is there a different master cylinder and booster for disc as opposed to drum brakes?

I may have answered half of my own question by looking in the year one catalogue. It lists and shows a different master cylinder for four wheel drum brakes as compared to disc\drum brakes. It looks like the front chamber is larger on the front in disc brake application. Is this correct? What about the booster. Is there a different power brake booster for disc\drum brakes as opposed to all wheel drum brakes?

Good basic info. Good luck!

Hey M M - Nice link - It explains things very clearly! I'm believe I'm in the early stages of Alzheimers and need pictures and plain english like that.

I tend to forget things and need pictures and explanations as well because I tend to forget things....... and sometimes it helps to have links and documentation if you are like me and tend to forget things.....what was I talkin 'bout? Oh yeah, sometimes I forget things too....... smile.gif
