That's what I typed first but then I thought that was Chrysler. You're right Ford and Chrysler is 4.5" and GM A body is 4.75". I've only had one A body in my life haha

Another thing, Disc brakes are just plain simple and easy to work on. You have 2 bolts that hold the caliper on, 2 pads, 1 rotor no adjustments needed. Disc brakes need to be adjusted, they have a lot of little springs and shit, wheel cylinders, shoes and drums etc etc


I agree with you 100% there.

When I get my car going and I don't think it stops well enough I'll change out the MC and booster before I switch to disc brakes

Much easier, you'd have to change out all that anyway to switch over to discs.

Exactly...well you wouldn't have to

The Scarebird disc brake kit for our cars says you can even use the single chamber MC with it

But that doesn't make sense because I thought with a disc brake conversion you usually needed a propotioning valve since the calipers and the wheel cylinders won't engage at the same time or the same pressure. IDK but I guess Scarebird does know

How hard would it be to use say a....69 GTO NEW booster and dual chamber MC and make it work on my Star Chief? I really want a dual chamber MC

I can't imagine it would be too difficult. You'll have to change out the proportioning valve of course.

Well old cars don't have a proportioning valve. Actually only cars with disc brake fronts and drum rears have the valves I think. You don't need a proportioning valve on an all drum brake car which is what mine will stay...hopefully

Note - Scarebird's kits will NOT work with 14" rims. You need to bump up to at least a 15".

Right, that was where my project stranded - i want to preserve my 14" original rims, that i just got new whitewalls for. I have not found any kits that will allow these 14 " rims.
