  View original topic: '57 and earlier Rear Disc Brake Conversion
APLANTEDLEIF Mon Apr 12, 2021 12:44 pm

I was looking into doing a rear disc brake conversion on my 56 Beetle. It still has the original 1st gear non synchro transaxle and stock short axle tubes. While looking at various vendors I am finding out that they do not offer a rear conversion for '57 and earlier Beetles, at least with a stock/original transaxle but they do offer kits for '58 and later. What is it about the earlier transaxles that prevents the ability to install rear disc brakes? Is it the splines on the axles that differ from '57 to '58 and later or is it something else?

Thanks.

I just put disc brakes (CB Performance) on all 4 corners of my '56 and the only issue I ran into was that the parking brake cables were a couple inches too short. I ended up buying some barrel nuts and welding them to the ends of the cables with a couple inches of threaded rod. Everything else bolted up just fine.

ernstben, do you have a stock transaxle and short axle tubes like myself or did you upgrade to a later transaxle? I have read about needing to get longer hardlines going from the soft line to the caliper because of the positioning of the rear caliper.
