  • Brakes: 2R-15 brake cylinder interchanges?

    Hi All, My plans are to tear down the brakes on the 49 2R-15 after I finish some other projects this evening or tommorrow afternoon. I blew a wheel cylinder with the resulting total brake failure the last time I drove it. Luckily I hadnt ventured into traffic with it so the brake failure was scary but no real issue. Does anyone know of a direct FLAPS replacement for the wheel cylinders or am I relegated to use the SI replacements? Can anyone confirm that the ones supplied by SI are in fact direct replacements? Thanks, Steve

    As I understand it, rear wheel cylinders are unobtainium. Does SI have front cylinders for a 2R-15? I too would like to know if there are replacement fronts at NAPA, etc. One of my fronts has a slight leak.

      If your truck is a 2R-15 as you state my suppliers catalog lists Studebaker part# 683448 & 683449 1 3/8" (2 per side) dual rear wheel cylinders at Around $67.00 a pc. X 4=$268.00 Fronts I do not see listed for a 2R-15. Most of the vendors buy from the same supplier so you can buy from any of them. They may have to order them for you.

        That's interesting. The parts manual shows the rear brake with two cylinders per wheel (FR2 type) AND the hi-tork rear brake, which is what my 1949 2R-15 has. However, the service manual only shows the hi-tork. Anyway, the hi-tork cylinders are the ones they tell me are not available anywhere.

            Rear High Torque cylinders are available. They're priced in the neighborhood of $175.00 ea. Fronts are available, also. I don't have price information on them at the moment. Bo
