My Trail Boss has an aftermarket Magura brake master cylinder. The seals have all dissolved because the dealer specified DOT 3 fluid. Magura no longer makes these master cylinders or repair kits. The OEM part is worth more than the machine, which I use for towing a log splitter in the woods. Does anyone know of an aftermarket master cylinder (LH) that would be suitable?

 

#2050073 at Cycle Parts Warehouse for the updated replacement assembly for the 1992 250 4x4. $125 Don't know if this is too high for you? Magura parts are expensive,used em on KTM bikes. They used either dot 5 or mineral oil on most of them on the master cylinders and hydraulic clutch assemblies. OR you can try Ebay,but liable to get one as bad as the one you have if you go for a used one. OPT

 

Thanks for the prompt reply OPT.
I found this online and will try it.

I need to limit how much I put into this old machine.
I'll post here if it works.

About as cheap as you can get on the price!! Hopefully the threads will match up Or a little "riggin" may be necessary. Good luck OPT
