I've looked all over to find a replacement brake master cylinder for our disc/drum 1971 Runabout. Is there an interchage with another combination or will I have to just try and make something fit?
-
I ran into tbe same problem with my 73 wagon but fortunately my master cylender id still i good condition
I did score a rebuildable core and am going to investigat finding a rebuilt kit that will fit.
I assume that if you can find a rebuild kit with the same sized rubber parts you could rebjild the one you have.

And if all else fails there are a couple of place that will sleeve your master cylinder for you. It is not a cheep way to repair but I understand it is a stainless steel sleeve so should never give an issue. Last time I looked into it was around $200.00 for that sort of repair.

Rock Auto shows them for $73. l have a used one from the Pintoracer that was working perfectly, it was a new (not reman) Raybestos, maybe 4 years old. $30 plus shipping. Also have the complete disc brake set-up for sale (possibly without the rotors, another member inquired about them but has not commited to buy.)
-
Do you know what the port sizes are on that M/C you have? The RAYBESTOS MC36319 is listed on RockAuto, but when I try to buy it's actually out of stock. Go figure. I see there's a 1/2-20 3/8-24 and a 1/2-20 9/16-18 for port size combos. Not a total dealbreaker if we have to change some fittings.
-
Mine has a step down adapter in the rear port so l'm guessing it has the 9/16-18. So the 74 up will probably work
-
Later models should work as long as the bore and piston sizes are the same and you can find adapters for the ports
Alzo while we are discussing brakes..
Has a yone experienced the rear brakes on a disk drum wagon locking up prematurely during hard braking.
Mine seem to do that a lot even on dry roads.
I also have organis pads on the front and 14" 205 tires all aroind.
I have been contemplaring getting a adjustable proportioning valve for the rear
-
YES! I thought it might have been related to my using a drum to drum full 8" rear end swap and something having a minor difference. With the added weight of the 2.3/turbo it seems to make the car nose heavy but I still feel there is just a natural inclination of the rear to get light during heavy braking and cause the lock up.
