Corvair disk brakes

Can anybody tell me if they make a disk brake set for a Corvair front end, or if there is a stock item or a junk yard piece that would fit on my spindles.

Clark Corvair sells a kit for about $475 complete. Their website is: http://www.corvair.com/index.html

I had a corvair suspension under my 32 Chev sedan. Converted it to disks by doing this.
Used 73-74 Nova spindles, rotors, brackets, calipers. and pads. Modified the upper corvair control arm by hogging out the ball joint hole just a little and putting in a Nova upper ball joint. Had a machine shop carve me some bushings to fit between the lower Corvair ball joint stud and the lower Nova spindle hole. The taper is the same, but the diameters are different. Seems like I remember putting a small spacer behind the inner bearing to space the rotor away from the end of the upper arm. That's about it. The car would stop on a dime. Good luck.

I did the exact same on the EXSEDAN.....here is something to check before you drive it. During the build-up of the front, put the entire set-up together EXCEPT the springs. Then move the entire "A" arm, spindle, disc, caliper[loaded], brake line, up-down-around into all possible positions, turning the unit right and left as far as possible. Check for areas that rub at the extreme positions. You will prolly have to grind some clearances in a couple of places. This is CRITICAL...and here is why....A friend and I built a '34 Dodge Truck [they have suicide doors and look chopped], put a corvair front in it and everything looked good. About a month after getting it on the road, his son came back after a delivery, and he had hit a trash dumpster and claimed that the brakes failed, but after pumping them ONE time, they were OK again. We tore everything down and inspected every nut, bolt, item. Drove it around and tried to duplicate the problem. No luck. A few weeks later it happened again. This time it was when driving into a driveway that had a considerable rise and turn to the right. We were able to duplicate this and finally found that when turning sharply in either direction AND going over a bump that would push up on the suspension, the caliper was being pushed sideways and the fluid was being pushed out of the cylinder. You would then have to pump the brakes ONE time to push everything back into place. NO BRAKING for that one push......jb EXSEDAN
