antique61cmodel Posted October 24, 2014 Share Posted October 24, 2014 hello everyone i am in the process of trying to restore a 1961 Mack C model fire engine and the rear wheel cylinders decided to go on it when i stepped on the brakes one day and come to find out that they are almost impossible to find i have the original manual for the engine and all the part numbers to go with it, i will list them below with repairing the rear wheel cylinders i am also on the lookout for the master cylinder for the engine also i will list both part numbers below if anyone has any idea on where to find either new, good used, or even rebuild kits for both objects that would be great i really appreciate your time in reading thisthank youandrewpart numbersbrake shoe cylinder: 48sma31master cylinder: 2qea4253 Quote Link to comment https://www.bigmacktrucks.com/topic/37486-wheel-cylinders-and-master-cylinder/ Share on other sites More sharing options...
Popular Post 1958 F.W.D. Posted October 24, 2014 Popular Post Share Posted October 24, 2014 There is a 99.99% chance that both the wheel cylinders and the master cylinders are NOT OEM Mack parts- that they are most likely Borg Warner, Bendix or Wagner. Take the cylinders and the master cylinder to an old-school NAPA parts counter- NOT one of these new fangled chain stores, The older the school NAPA place, the better, and the older the guy behind the counter, the better. Drop them on the counter and say "I need rebuild kits for these or new units." Here is the key:DO NOT TELL HIM WHAT IT IS OFF OF. MAKE NO MENTION OF A C-MODEL MACK. THAT WILL ONLY CONFUSE THINGS. Again: old-school NAPA (or another place....old school!!!) drop parts on counter- "get me these." If you walk in and it's a young kid, ask for an older guy. If there is no old guy, and the kid goes to the computer first, turn around and walk out, go somewhere else. (My 1958 FWD Firetruck has a 1957 Ford master cylinder for the clutch slave cylinder. There are both rebuild kits with stainless steel parts and new units available through Wagner.) 3 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment https://www.bigmacktrucks.com/topic/37486-wheel-cylinders-and-master-cylinder/#findComment-264315 Share on other sites More sharing options...
yarnall Posted October 25, 2014 Share Posted October 25, 2014 I agree with FWD. The other option is getting them rebuilt. I send mine to White Post Restoration. They sleeve them and rebuild them. It is more expensive than new if you can find them but they have a life time guarantee. I don't know whose life time but hopefully not the former owner because he died a few years ago. White Post Restoration. One Old Car Drive PO Drawer D White Post, VA 22663540-837-1140You can download the form off their web site and mail them to them. www.whitepost.comI wouldn't use the postal service because they lost the wheel cylinders and master cylinder off my 405A. I had them insured for $800 but it took me a long time to find replacements to have rebuilt.
