I do know if you push the slave piston in after it's been allowed to move out so far,the fluid WILL rise back up into the reservoir.If it it continues to "move" outward,you will begin to lose fluid at the slave piston. I've had that happen.
You do not lose fluid behind the piston. Then if you lost fluid, it is out the banjo, out the nipple, out the quad-ring. Show me the loss where you would have a spongy lever pushing at fluid with an air bubble inside. The tiny rise back is whatever expands in the line, whatever extends the piston at the caliper, whatever the master piston takes up then all is returned back. Remember that master's piston has to compress the fluid. So right there, you see how very little is going to return if the master is first loading up?
But I've never heard of fluid coming back up a line like that(except with the clutch line).It's odd anyway.If it expanded,it should have pushed the diaphragm back up into the cap where it was to start.
How can it push the diaphragm back up, when you already flatten the pencil point getting your point across. If you were to write this out, you'd be at that sharpener about 3 times already, someone change the pads, Hurry! Oh, yer gonna grasp this! Simmer down, Flow Chart, DIS is not rocket science [hand over mouth img].
I think there's something going on with Gordon's pistons.The pads aren't retracting far enough or something.No leaks,no air.Closed system.WHERE would the fluid disappear to?The volume is the same.The only thing maintaining the level is the pistons/pad thickness and the amount of fluid in the lines.
There is not a thing wrong with bg's brakes if he came back, said no change. After all those miles, one questions the fluid, the other questions where the fluid is going, the bike tells you that you are assuming something is funny, or something is wrong? Remember, this is the internet. One man's cap removal is another man's hand waving, yelling there is a problem with the pencil sharpener, someone point the way to another one!
You have this accordion effect of each fold sort of pops 0ut in place. Once that one accordion fold opens, another fold is to follow. That diaphragm is stuck on the suck, as it follows the amount of fluid the bike started with. The fluid that went nowhere without a leak to be told, but travels farther down the line; sits in back of the caliper's piston. There is your lost or can't figure out why the plastic fill line didn't follow the fluid. It displaces that cavity the piston came out of. The Quad will have no pressure on it via the piston can rock back and forth but eventually move out of the caliper, obviously and stay there. It's all sort of subtle are the moves.
No fluid is going to head back up, sitting in that piston's machined out chamber of the caliper it just filled. Speed the brake pad wear and how will the oil return> Did the diaphragm follow the flow? Did the master's piston push fluid against it's now closed holes in the master? All that happens now is that lever forming a closed hydraulic lock. You control how much pressure to apply on that brake disc.
You feel that modulation or warp. That is the disc coming around on the highest spot, pushes the piston(s) back in, your lever goes out. The disc is still turning, so you fell the lever go back to normal until that high spot comes around over and over. Did the piston at the master expose a hole it pushed it that far back? No. When you release the piston at the master, does not that need filling or neutralizing or back to no pressure at that the brake lines say?
Did not that one big hole in the master, have to fill that gap you reapply? Is not that tiny hole the diaphragm sucker? Kind of the [psi] neutralizer? Tiny hole sucks all that 14.7 back and forth, someone is going to eat pressure somewhere. Get it? Then we see how that diaphragm acts as that neutralizer and keeps that air from being sucked in the hole we get deeper down the pad say?
We sucking any of this up?
