    I have just acquired a 1933 Chevy Eagle coach. I want to convert to hydraulic brakes (drum or disc) but leave everything else original for a while.
    What is the easiest way ? I looked into disc front brakes but the ones I found require 37- 48 spindles which I don't have.
    I used to have a 36 Chevy which was the first year for hydraulic brakes and were much safer than the mechanical brakes that were on my 31 Chevy.
    Looking for some constructive advise. Thanks

    The G.M. parts catalog lists the same front spindle on straight axle cars from 1928-40, so at least on the front, the 1936-50 style hydraulics should fit. So far as interference with the stock 1933 wheels goes, I can't say.

    It will never go fast enough for disc brakes so why ruin a beautiful car? A nice looking car like that will not be driven a lot so the original brakes will definitely do the job.

    Ok if I can hit the correct recall ****on in this old head . 49 -54 backing plates , 64 hubs and drums , gets you tapered roller bearings , 5 lug front drum brakes . Also some simple spacers needed between spindles and backing plates , can’t recall if OEM spacers or not . Rear , 55-57 rear will fit the OEM springs perfectly , only issue make a lowering block with 1 1/2 offset to rear and done

    fifty years ago I used the 53-54 backing plate and brakes, had to swap an inner bearing?? maybe on my 38 Chevy with a beam axle, I had to used washers to space out the backing plates. I should have left that axle in the car:( It stopped very well and I also used a 57 Chevy rear axle. I suspect I got my info out of Hot Rod Magazine....it was a great magazine then.
