thanks for your replies, reason i asked is that i fit new m/cyl early dec and now 1 wheel cyl has started leaking. It may just be coincidence, but i filled it back up with brake fluid.
when i ordered new cylinder from tvh there was warning about correct fluid.
I think the cylinders are correct because there is only 1 that measures up (1" bore) but I also started looking at master cylinders on tvh and noticed that all kalmar m/cyls list brake fluid.
dont want to fit new wheel cyl and that to go belly up in another 2 months!!!
things like that get you a bad name quickly (and cost you money)
