Bleeding Bloody Bleeding Brakes

if fluid doesn't leak out, then it's fine.

I'm not convinced on this just yet.

Used to think the same, but then I started to consider why motocross bikes have air bleeders on the forks. They mostly aren't leaking fluid, but they all need to let the air out of the forks after a race.

Probably should note, they're tested with fluid at 4500psi, not air. But either way, it doesn't actually matter if you're convinced or not.

Are they actually bleeders? I though they were used to set the base pressure. You'll be able to 'bleed' air out after a race cos the oil/air will have got hot during. And bleeding before a race may well be just letting air back in since it has cooled down and lost pressure from the last 'hot' bleed.

Yeh pressure testing with gas is generally a bad idea...

Air preloading went out with damper rods bro.

Gas forks these days, are sealed cartridges to reduce cavitation under and above the piston. The extra spring effect is a negative by product, but the lesser of two evils. I think the new systems might not even have said spring effect, but I don't know for sure.

I was implying (but maybe it was too subtle for your superior self), that I would like to know why you think air cannot be dragged back past the seals, rather than the piston return. I used motoX forks as an example of this happening in other applications.

Clearly you're too clever to waste your time for the likes of me though, and would rather be condescending instead.

Jog on.

I'm not sure what you expected... you used a completely unrelated example; completely difference stroke, completely different seal type, completely different application. If you don't want to be dismissed as a muppet, try applying some critical thinking of your own instead of blurting the first thing out that your two brain cells come up with. I knew exactly what your were implying, it just wasn't worth my time

gwigs. Has anyone suggested having a look at the brake lines? I wonder if a big part of your problem is the brake lines swelling when you apply pressure

Well after waiting for months for new calliper pistons I find out from the parts people that Suzuki dont make them anymore.
So I tracked down some second hand Callipers...brakes still no good ...put in mastercylinder kit...brakes still no good..
Put new braided lines on two days ago and yipee I got brakes again...so you are right on the mark there
