With the engine on and at idle. I think its very firm at the biting point. But i have a small problem, the brake lines were incorrectly connected to the master cylinder, the left front wheel brakes less then right wheel, and probably it happens on the rears as well. Its just a matter of swapping 2 brake lines. And the brake pads dont handle heat very well, already have some Bendix pads to go in.
What will you do mate? Get another master cylinder or live with the stock? My 11yrs old cylinder was ok, but you can take it off and check it for problems...
i think i'll live with it. it does its job and the teeny squishing is minor. i spend most times at the biting point and only feel the squish when really braking hard like emergency stops. how do you check the master cylinder? it doesn't leak down when keeping steady hard pressure on it.
