Disk Brake Conversion

64Cutty · February 7th, 2007, 12:26 PM

Hello all. I'm new to the Oldsmobile circle here and I just got a 2 door 64 f-85. Its running the 330 2 barrel and the 2 speed auto tranny with 4 wheel "suicide" aka manual drum brakes. I was wondering if anyone knew of a junkyard crawl style disk brake conversion. I dont want to buy a thousand dollar kit as I'm trying to build this car on a budget. But If I could get some parts from a yard and put them together to make it, I'm good with that. Any help would be appreciated. Thanks.

From what I understand the 1964-72 A body will all interchange. The 1970-72 are pretty common to find disc brakes on, and a Cutlass, Skylark, LeMans or Chevelle will all work. Also, the wagon or 4 door cars would work. I've been told, but am less sure that the 1973-4 Nova, Omega, Skylark type cars will work too, but with the steering linkage behind the crossmember you have to swap the spindle sides, the right on the left, then left on the right. Be sure you get all the pieces, the distribution block on the frame and the little "L" brackets where the rubber hose from the caliper to the frame are different on drum and disc brakes. I've put 70-72 disc's on 1968-69 cars and it's a bolt on application. John

Thanks for the replys fella's. Oldsguy thanks for the welcome. I only wish I would have seen the brake forum before I posted here. Kinda feel like a dumb arse for that one. Anyhow is there any other conversion that you know of. 2blu are there any other ones that you know of. Those cars you mentioned are hard to find in most boneyards you go to now a days. Even still I'll start looking around and seeing if I can find any them around these parts.

Welcome, 64.

I'm not sure if a 70-72 setup would work. I read on another site that it moves your wheels 1/2" outboard (enough to possibly scrape tire to fender on bumps). I don't know that for a fact (as if I know ANYTHING some days), it's just what I read.

If you find some in a yard, don't forget to snag the disc brake spindles too.
