Working on a 1949 Olds 76 coupe (Olds 455, TH400) The front drums are currently stock. Going to convert these to 49 88 front brakes. My question is the stock 76 wheel cylinders are 1 1/8" whereas the 88's are 1 3/32". The shoes for the 88 are slightly larger than the 76. My question is, the larger wheel cylinders, 1/32 difference are readily available, but the 1 3/32" are harder to find, and expensive when compared to the 1 1/8" cylinders. Will the 1/32" make a difference, when considering the larger 88 brake shoes? I think with the different driveline, and the slightly larger shoes, the increase in brake volume/pressure will be negligible at best, and honestly, i cannot believe this is really a big issue at all. I would guess that many people run around with the larger cylinders on, without a second thought, and if they are both replaced in a pair, will have little to no effect. Thanks in advance, I appreciate the advice!
