Mystery Master Cylinder

Recommended Posts

I own a 1936 Buick Series 40 (Special). I am rebuilding the master cylinder and noticed that the part number stamped on the casing is 5450221-3-N. It also says "Model 321A." I looked this part number in my pre-war Buick parts manual and it wasn't listed. I was wondering if someone who has a post-war Buick parts manual can see if this master cylinder part number is listed and for which year/model Buick? Thanks a lot.

PACKICK, "1946-57 Buick Chassis and Body Parts Catalogue 574-B" doesn't list part number 5450221-3-N. Note that my copy was published by General Motors Products of Canada. So far though, I haven't found any differences when hunting for parts in the US.

Listings for regular (non-power) master cylinders are:

Group 4.650 CYLINDER ASSEMBLY, BRAKE MAIN

5450320 1946-49/ALL

5450225 1950-52/ALL, 1953 Model 43

5454242 1953 Model 45 Exc. Dyna Flow

5454179 1953 Model 45-47 Dyna Flow - exc. power brakes

5454350 1954-55 ALL - exc. power brakes

5456000 1956 ALL - exc. power brakes

5456127 1957 ALL - exc. power brakes

It's unlikely any that a power brake master cylinder would have ended up in your '36 Buick. However, just to be thorough, those part numbers are:

Group 4.901 CYLINDER, BRAKE - WITH POWER BRAKES

5454800 1953 Model 45-47, 1954/ALL - with campaigned cylinders (?)

5454975 1955/ALL

5455060 1956/ALL

5455865 1957/ALL supercedes 5455850

Sorry that it doesn't solve your mystery but at least maybe it narrows down what your part doesn't fit.

Hi Packick,

Make note that casting numbers on parts are'nt always exactly the numbers in a parts manual. I found that out from working on tons of cars and a few years in a Chevy-GM parts dept.
