Inverting Avid Juicy Brakes
atlaz, isn’t that one just going to be the pistons re-adjusting?
What I’m talking about it when you lay the bike on its side to open a gate/go for a pee, whatever, and then the blade comes back to the bar. After a couple of squeezes it’s fine again. No sponginess, no fade at speed, just does its job.Posted 8 years ago
Has anyone else noticed that if you lay a bike down or roll it along on the back wheel with Avid brakes, they sometimes then let the lever come back to the bar? It’s not the end of the world, you just pump the lever a few times and everything is back to normal. I’ve noticed this on a few bike now but it only seems to be Juicys. I did wonder if it was a sign of air in the system (even though the brake doesn’t feel spongy) but bleeding doesn’t make any difference. Sometimes both levers will do it but it does seem to be the rear more often than not.
Anyone else notice this or am I just suffering some strange jinx?Posted 8 years agocoatesyMember
Before you finish bleeding the lever, try inverting it and giving it a few taps and then try sucking more air out. I’m convinced that air gets trapped under the diaphragm, inverting it then releases it and allows you to suck it out(or allows it into the system if you leave it there and pull the lever).Posted 8 years ago
What it seems to be is that when you suck the air out of the lever, it causes the diaphram to collapse. So, all I’ve done once I think all the air is out is to push back on the syringe to reinflate (?) the diaphram. Seems to have worked on two of the brakes so far. I’m just going back into the garage to try the third and final brake.
In my defence, it doesn’t mention pushing in the bleed instructions, just pulling.Posted 8 years ago
