This J-200 Kaiser -Willys-Jeep pickup has 2 individual Brake master Cylindars , apparantly One for the front axle and one for the back . and they are BAD..NAPA can't find a listing ,, but Tony was not in , maybe gonna have to go back to NAPA on monday , , SO I, went to O'rielys , WOW , they had one on the shelf but it was single reservoir type.and fits many applications . it is supposed to fit the J-100,, no go , O'Rielys Spent 10 minutes on phone with parts rep in indy trying to find right parts ,before folding ,... Again James Believes he can talk to his normal guy parts rep on Monday and Match Up the Parts ,, seems to be a common setup similar to brake master cylidars on LA Case , 300 massey combine , GLEANER F and my 58 chevy grain truck ,, dont know what to do, but wait , You guys may have better Ideas ,, so chime in ....
 
Rock Auto dot com says that the manual brake master cylinder is either Raybestos number MC21000, or Wagner number MC34224 [F34224]. The Raybestos master has a 4-bolt mount, according to the illustration; the Wagner has a 2-bolt mount. If it's the Wagner, Rock Auto is about $30 cheaper than the online price for the Corydon O'Really's store [I call 'em that because, when you tell 'em what your vehicle is when it's old, they usually say, "O, really?"]

And Tony's probably delivering his AVON orders....
 
I'll admit to knowing almost nothing about Jeeps, so everything here is a guess.

IH PUs of the 60's with manual trannys used 2 similar looking "master cylinders" on the firewall. In fact, left one was the 'master' for the hydraulic clutch, and the one closest to the hump in the firewall was the brake Master. Later, the brake master was split into 2 chambers to supply the fluid to the 2 separate brake circuits (maybe 1968). And the clutch master remained a single resevoir. IIRC, both of these masters were rectangular in shape, and cast steel.

Jeep and IH shared a lot of parts and design features, so maybe this is of some value to you.

Actually, the IH pickups/Travelalls from '61 thru '66 used a single-reservoir, dual-piston master cylinder. Brake and clutch shared the reservoir, with the left piston serving the hydraulic clutch and the right piston serving th brake system. But it was a SINGLE master cylindr; my '66 1100 parts truck still has one.

In 1966, the National Highway Traffic Safety administration decreed separate reservoirs for front and rear brakes...so in '67 IH switched to separate brake and clutch master cylinders. The clutch master was similar to the old "fruit-jar" master used on early Mustangs and Novas of the '60's. [The Nova master isn't an exact match, but it CAN be made to work on the IH.]
