I have a 68 and it has a brake booster for its 4 wheel drum brakes. It appears that this wasnt in the option listing in 68 so this isnt a factory set up.In the future I wish to convert to front disc brakes from SSBC, and I wonder which parts to order. I guess what I need to know is what kind of aftermarket power booster I have so i can tell SSBC before I order any parts. How can I tell what kind of booster I have? Will it even matter at all? Any insight will be appreciated, im a long way away from buying any parts but Im figuring out my strategy in advance of buying wheels to make sure the wheels will fit the brakes I want. ------------------ '68 coupe 289 C code 66 heads, edel 600cfm carb, performer intake, dual exhaust

indyphil; I have the same setup in my 68 coupe, I am not sure if it was factory offered. My mechanic installed the power booster with dual master cylinder, after getting it at the local auto parts place. I am also planning on installing front disc brakes and will be interested if the power booster has to be changed or can be used with the power front disc brakes.

It shouldn't make any difference to the rest of the setup. The master cylinder should be the type with two different-sized chambers though. As for the type you've already got, doesn't it have anything written on it?

Back then this was a popular thing that the dealer would install. It?s the master cylinder that should only be different

Did that swap on a 68 one time. Used the disc brake Midland booster along with a longer power disc brake pedal. This is recommended procedure for successful alignment of components. It worked quite well. Master Power Brakes sells the parts that would be needed. A Midland booster is about 7" give or take, in dimater and about the same in thickness. If it doesn't have the aluminum and plastic spacers at the front of it, don't buy it. It also has a band that goes around it. It has a two outlet vacum port, also. They were the set up for 67-8, possibly 69.For daily use, the power drum setup worked as well as the discs. If I had a setup that worked well, would keep it. There were road tests when those cars were new that supported that premise.

Oooo, could you clarify? One day, when I find a disc brake pedal, I'll be buying a Midland. What's the deal with those spacers? Are they often missing? Is the unit useless without them?

The master cylinder I have now has equal sized chambers. It has since I bought the car, and also since I replaced it about 6 months ago with a basic 68 master cylinder from NAPA. I understand that the disc brake kits come with new master cylinders. So what you are all saying is, so long as i make sure I get a DISC BRAKE master cylinder with the kit, it wont care if theres a booster installed or not? ------------------ '68 coupe 289 C code 66 heads, edel 600cfm carb, performer intake, dual exhaust
