What do factory master cylinders look like? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Close-up pics of the cap appreciated as well, I wouldn't mind trying to locate one.

I don't recall, did Bendix and Moraine boosters use the same master cylinder? Seems they don't. My 1971 C10 402 has a Bendix booster.

Thank you

They don’t. The mounting holes are spread differently, with the delco being wider. The bendix is much easier to source. Going through this right now as I have a delco also. I may just buy a rebuild kit for the one I have.

Nice you know how, I sent mine out to Oregon for a rebuild, I think it was $260 with shipping.

Pics of original for Bendix master cyl. caps anyone? Leads on a nice replacement appreciated as well.
