Dual circuit master cylinder for early 4 wheel drum VW?

There is a ton of talk about which dual circuit MS to use if you are doing a front disk swap, but i have 4 wheel drum on my 62 and would like to replace the stock single circuit MS with a dual circuit one. are there any available for this application? i find it hard to beleive that there wouldnt be. Could the DSMS for the disk conversion work on a 4 wheel drum application? part number 113611015BD is the one im looking at...nobody ever specifies if it can be used with 4 wheel drums, so i dont know what to buy...any help would be great!|||From 1968 on the master cylinder was dual chamber in all VWs. All will easily fit. I believe they all use 2 bolts, side to side, with the same distance between them. There is plenty of room because it points into the empty space under the fuel tank. The lines attach the same. The only difference is you won't have any dash light for when the master cylinder shows a difference in pressure between the 2 chambers. But you could easily add that.|||My 1972 Beetle had DCMS. It had drum brakes.


I don't think it matters abt. disc or drum . The MS works the same on both.


But I'm no tech, so you might want to check with one of the 'Ask a Mechanic' web sites to be sure.
