F15a brake master cyl.
 

I did a search here and came up empty, so am just wondering if anyone has a aftermarket part # for the brake M/C on a '43 F15a? The one I took off had a 1 1/4 " bore but I am not sure that is correct. All the master cyls. in old civilian brake catalogs show 1 1/16 " bores. Likely doesn't make much difference, but what is everyone using for M/C's now? Thanks for any help,Dave

The current production Master Cylinder (1 1/4" Bore) is part number 4572. This number is common to various brands (Wagner, Raybestos, etc) and may use their prefix, eg WG4572, MC4572.

A Google search will provide range of vendors (and prices!), but I also think Raybestos have a plastic fill cap and the Wagner uses a steel nut (larger than the original Ford), that might be something to keep in mind when comparing prices.

I used to recommend rockauto for these, as they were available for around $35 each back then and someone like NAPA wanted $350. But I see NAPA has them under 4572 for retail $133 and trade price of $75.88. There is actually stock of one in Brandon.



I still see them at reasonable prices from Rock auto, but to the point where shipping will put it over. Centric 13079001 and Dorman M4572 are the lesser priced examples.

Rob, do you know if the same part will fit a C-15A ? I know , i know , Fords are sooo much better !

No, Chev Master Cylinder is a different design altogether.

I think there have been threads about the modern unavailability of Chev style M/Cs due to the CMP having a style quite different to Civvy vehicles of the era, but a solution is possible with a close enough alternative.
