avanti brakes

[thunderations]

Only the disc brake cars had the 3/4" rear cylinders on the 11" rear brakes. V8 drum brakes would be 11" front and 10" rear. Using the 10" rear brakes with an aftermarket front disc set up would require doing some research to get the right size rear wheel cylinder, but I would think that the 3/4" cylinder that Studebaker used would be the best option. Your dealing with pressures and a proportioning valve might be needed.
If yours is a stock drum brake system, I think 1" rear cylinders are correct. Using larger would decrease pressure.

The main reason I asked is I found a online vender on ebay not a Studebaker vender I hope that listed a rear wheel cly. for Avanti's and thought that should be the same as my hawk. The more that I checked into it they are over 1" and listed as for the rear on a drum brake car.

Did the 63-64 Avanti ever come with drum brakes?

They all did (came with drum brakes) - - on the rear.
All Avantis came with disc brakes on the front.
Some Studebaker Avantis were later converted to drum brakes on the front. There is a previous thread/topic on this.

What about the 1949 Crosley? Were they optional? Also Chrysler Imperial in '49 had disk brakes on their Crown Imperial. Also, don't know if they were standard or optional.

The Mopar system was totally unlike what we recognize as disc brakes. They did not have a caliper but pressed the disc sideways; more like a clutch and pressure plate.

Crosley had what was called spot discs. The Avanti was the first American car to come standard with modern caliper disc brakes...even if they were license built from Dunlop.

NO, First American production car to come standard with front disc brakes. Rear brakes were all 11 inch drums.
