I'm planning to change the front drums to discs on my fastback. As I'm cleaning up the brake pedal assembly, I've learned the power brake booster requires a different brake pedal (which I likely have in the pile of extra parts).

I hadn't really considered going from manual to power, but maybe I should/could. Anyone have a compelling argument to install a power booster, etc?

Thanks!

Craig

One thing you need to be aware of, I recently learned myself, is that power brakes work off vacuum generated by the engine and if you have a radical cam, you may not generate enough vacuum to make the "power." You can get around this with a cannister that (I guess) stores up the vacuum somehow, but it becomes more clutter under the hood. Be sure to check this out before signing on for the power booster. Good luck. randy

Less pedal effort is required.

This is more important with the single piston discs than the earlier 4 piston discs.

I changed out my manual drums to manual disc. I probably upgrade to Power disc in the future, but for now I really see no need to. Manual disc work fine. You don't have to change your pedal either. Several companies make Powerboosters that work with your manual pedal using an adjustable rod. Transam racing is one. That will probably be the one I go with when I decided to go w/Power Disc.

I have a 68 and I got a 68 disc setup off ebay with the booster and pedal. The hard part was drilling a new hole in the pedal support. The power pedal has a higher pivot point in the support. Some 68 supports supposedly have the hole drilled - of course not mine. Very happy with the power brakes. If you don't care about it not looking stock, just get one of the power brake conversion kits I've seen in most of the major shops (NPD, VA Mustang, etc). You can re-use your current pedal and support....

The pedal effort...(how hard you have to push on the pedal) will be about the same with manual disc as it is with your drums....If you don't mind "standing" on the brakes... manual is fine....just don't go into it thinking that because you've changed over to disc...pedal effort will be easier....Good luck!

I got a brake booster when I still had 4 wheel drum, and the one I bought didn't need to change anything and the brakes worked fine. Now I just installed front diss and still have the same booster and it still works.

Thanks for the input. I'll probably continue with manual discs, and then if I feel the need, well - then I'll do the upgrade.
