Next item on my rebuild list is the brakes. If it matters, it is a Waldon loader. They are hydraulically applied wet discs.
It has a conventional type master cylinder that supplies oil to the brakes. They have been working when I press the pedal, but I took the cap off to check the fluid and was not pleased at what I found.
The "fluid" that was in there was severely contaminated. Very thin, but with like chunks of grey slime in it.
I disassembled the master cylinder and found very little corrosion. Which surprised me given the condition of the fluid. For now, I just reassembled with the seals that where there, as they looked adequate. I will work my way down the system cleaning out the old, nasty fluid, but what do do for new brake fluid?
My experience has been that hydraulic oil would be the likely fluid to use for sealed brakes, but with the viscosity of what came out of it, it was likely mostly brake fluid. But, past maintenance of this loader was very much hit and miss, so it could have been wrong.
Brake fluid is sort of a one way street I guess. Once the seals swell, can't go back. With oil, it should function even if wrong? Like I mentioned, the brakes have been working fairly well in the short about of operation I have done to this point.
Anyway, any advice?
Thanks
