Can someone help here? This spring my front brake handle felt just a bit soft and braking on front got weak. Foot pedal which I understand does do a little of both front and back brake still worked well. I bled the lines (could there be a proper way to do it??) and no difference. To my knowledge there is no hole in the line and if there was wouldn't the symptom be that you squeeze front brake and it just goes completely soft on you? I can always maintain a little 'squeeze' in the handle and can pump it up to a higher pressure with a few rapid squeezes.
It sat most of the summer and when I tried again it again seemed to favor the front right tire and when you braked with front handle only it pulled over to the right while braking. I rebled the front lines again. The right front builds pressure and shoots a nice jet of brake fluid out every time. The left is inconsistent. One time good, then the next 3-4 times just a partial bleed. I thought maybe since the stream on bleed is weak that the bleeder isn't opening all the way and that may be part of the issue, but once it is closed again it shouldn't matter as long as it seals (and as long as there is no air in the system)
The rear bleeds fine.
It acts as if fluid goes slowly over to the front left brake caliper. What is the symptom of a line that is partially pinched or occluded? Are these lines flexible or rigid? Is there a usual pinch point if that is the problem? Does a bleeder actually go bad and have to be replaced outside of an obvious leak? I have no leaks underneath on the clean garage floor.
Is there a way to detect a tiny leak in the front squeeze handle or reservoir? I can't imagine a leak in the reservoir as then the right and rear brake wouldn't work well as they do.
But I'm looking to the pros. I had hoped by just moving a lot of brake fluid through the left line that would help but the behavior doesn't change, it just seems one out of 4 or 5 bleed attempts will give a good shot of fluid, the others a weak shot.
Thanks in advance!
