Post rear drum to disc conv.

Anyone know a cheaper way to convert rear drum to disc brakes on a 1980 trans am. A machinest told me he could make brakets for me and get front calipers and rotors from a ford festiva. would this work? Any other ideas?

I don't know anything about the Festiva front brakes, but you will need some kind of parking brakes. Don't think front calipers will be set-up for that. I personally would be more inclined to go with something that has larger brakes.

Some front drivers have park brakes on the front calipers. I know Subarus do. The Festiva front brakes should be adequate for rear brakes on a larger car. If you want a park brake you'll have to use a caliper that has 'em or go with a pinion shaft brake. I've seen a couple advertised, basically a manual caliper that clamps on a small rotor that bolts to the universal joint mounts on the pinion. With that you can use GM front calipers on the back. I think S-10 4x4 rotors come off the hubs like a drum, so they can be used. Speedway (www.speedwaymotors.com -- they have a cool catalog with lots of info as well as stuff!) sells a kit for $275 minus calipers. Brackets, rotors, all hardware. Put GM front calipers on and go. The machine shop might be your best cost alternative. Speedway has bolt on as well as weld on brackets, or you can order a piece at a time.

should know, but you know how that goes. since it's a 2nd gen you can try this other site www.nastyz28.com and see what they have over there since your car is essentially the same thing. happy hunting

Try checking out a wrecked Pontiac Fiero, it has four wheel discs. The bonus is that the rear callipers have the park brake built in. GL

By the way didn`t some of the mid 80s trans ams and camaros have rear discs. You might try some of those.
