Re: What size Rear Wheel Cylinders?

Wait just a minute, now.

While the 1-1/16" size certainly matches what's shown in Section XXI - Specifications of the 1955-56 Shop Manual (as well as "Mechanical Specifications and Adjustments" provided in SC Vol. 29, No 13), there's a bit more to this story.

Take a look at the 1955-56 Service Index Brakes section, which shows a relevant topic regarding "Rear Brakes" in STB 56T-24. Although we do not yet have copy of that bulletin on file, here, I can tell you that it recommends use of 1" diameter rear wheel cylinders - same as used on 55-56 Senior cars. This information is reiterated in SSB No. 344, along with other checks and amended adjustment procedures, plus improved rear drums.

However, DO NOT go and simply order 1" wheel cylinders. These measures should ONLY be applied to those vehicles that exhibit a problem of premature wear and grabbing of rear brakes. It does NOT mean that ALL Clipper (and Executive) models had the problem.

So, BEFORE you order anything, I recommend you measure what's on your car.
