Master Cylinder Question

[oldodge41]

I purchased a master cylinder from ebay. Add described it as a used unit for a 1953 Dodge that may need rebuilt. I got it cheap. Looks great externally and in the reservoir. I took it apart today to inspect the cylinder and found it to be what looks like a new rebuild with a fresh brass sleeve installed. The rubber cup was stuck to the brass but popped free easily enough. Just dried up lube stuck a little. I have a rebuild kit here and was going to use it but the bore after the sleeve was installed is 1" versus the 1-1/8" of the kit I have for mine. Everything in the cylinder looks good but I would like to replace the cup with a fresh one because of how it was stuck. I have a 1" one from a wheel cylinder kit. Would that work? The one in it has a brass washer embedded in the back of the cup. My replacement doesn't have that washer. Where would I get a 1" rebuild kit for one of these? Did any of these cars have a 1" bore master cylinder? Thanks...........Tim

I think the rubber can be used if it is not torn... just lube it up with brake fluid... I also think the smaller bore would give a greater leverage... more pressure to the brakes with the same pedal pressure... but there might be longer travel of the pedal... I think... (of course I could be all wrong... I'm just a truck driver.)

I believe some of the Plymouths had a 1 inch bore, and the Dodge had the bigger bore, 1 and 1/8..

I purchased both the 1 and 1 1/8 kits from Rockauto because I had not pulled my MC yet and did not know which one I would need. I know from my searches that I will probably be using the 1 1/8 kit but we'll see when I pull it apart. Just check out rockauto.com under 53 Chrysler Windsor. I don't know if it will work though on a Dodge.

If I don't use the 1" kit it's yours for the price of shipping if you want it.

Thanks for the info guys. Al that 53 Chrysler kit looks like just the ticket. I never thought to look at larger cars. I had found a kit for a 64 Dodge A100 that might have worked but the one you listed looks more like it. Let me know if you don't use your 1" kit............Tim

Any 1949-52 Chrysler with the power brake booster use that 1" master cyinder kit.

No problem. I have some drawings to do today for my art class but if I have time I want to pull the old MC later. Otherwise I will pull it tomorrow nd let you know.

Later,
