I have a 69 skylark with 14 inch wheels and drum brakes. I just put new tires on the nice rally wheels and don't want to get rid of them, so is there a disc brake conversion kit that will work with the 14 inch rally wheels?
yes u can keep your 14" rallyes as long as the rim code is "JJ". inlinetube.com sells a complete drum to disk brake (front) kit. '69 buick had the same single piston disk brake set up as the 70, 71, 72, etc.
Any '70 to '72 A-Body car can be a donor for your disc brake setup. I took the entire power disc brake setup (booster, master, proportioning valve, etc) off a 1972 Pontiac Le Mans I was junking out, and swapped it onto my '68 Skylark. In my case, it was even upper and lower a-arms, because I had just rebuilt the whole front end with ball joints, control arm bushings, etc. Both cars had 14" wheels. Don't waste your time on the old four-piston setup. The pistons carried the seals, and the calipers would corrode, requiring honing as a minimum at rebuild time. Stick with the single-piston jobs.
