Braking News!!! Long

[55 Fargo]

Hi all, about a year and a half ago I redone my whole brake system on my 48 Chrys. This is what I did, media blasted the M/C and all wheel cyls, then they were honed and new kits installed. There was some pitting in a few wheel cyls, I then honed them a little more and took my chances.The M/C turned out fine and does not leak, 2 wheel cyls are suspect, and have shown slight leakage when the boots have been pulled back, so far I see no leakage in the drums, but the car has not been driven all that much and is really not on the road yet. I also replaced all the steel lines, rubber hoses, had all the shoes re-lined, the front and rear drums machined, the the fronts are now out of spec. Here is my question, I didn't realize I had 10 inch brakes on the front and of course 11 on the back. 11 inch brakes are stock for 48 Chryslers, so someone has obviously jerry rigged the fronts with 10s along the way.

My question is this, I want to replace all of the wheel cyls, I plan on buying from Kanters, are these a direct swap, as I have heard of replacement wheel cyls that had longer push pins or different pistons that caused problems, resulting in not being able to install the drums, until the push pins were modified.

I also have a pair of 11 inch backing plates and shoes and the hardware from Pat S, should I install these to replace the 10 inch brakes, the drums I got from Pat are in good condition and have a lot of material on them, don't think they were machined much or at all. Now will these 11 inch backing plates bolt right back on to the spindles I now have on my car, if not I have a 47 Chrys parts car in my yard, I can get the necessary parts from it.

Any thoughts on this from anyone. One other thing, I am using Dot 5 silicone brake fluid, I have had no problems, and it helps when a car sits a long time between rides, I know some people don't like the silicone, but there is always 2 schools of thought............thanx Fred
