I am having issues with rear brake and hoping somebody could chime in with ideas.
Here it goes.
Every so often air gets into the system. I bleed it and it's fine for some time but then happens again. This is my track bike and I only take it to track days twice a month. But even then I barely use them. How it lets the air in is beyond me. I checked everywhere for leaks, nothing.. everything is dry and clean.
On all the bikes I had owned this is the first time ever happened. If somebody told me before I would not believe it myself. Normally when pressure is lost there must be leak somewhere, but not this time.
Any ideas? What should I do, start rebuilding caliper, master cylinder?
Same thing happens to mine. I usually wiggle the arm where the reservoir line connects to the MC while pressing on the peddle and the air comes out. I'm guessing it doesn't seal well and allows air in.
Another thing I should probably mention is when I tie down the bike to the trailer one of the straps just about touch brake fluid reservoir. Could this be that vibration and potholes make the strap to shift reservoir so it lets the air in through the rubber hose?
Also, people who commute with their bike, can stop on an incline and rear brake helps to get going again.
If there is a stoplight on the incline, i usually sit straight, let off the clip-ons, right foot on rear brake and left on road.
Resurrecting this thread.
The update is this. I swapped brake fluid reservoir with a tube and thought that was it. It was not.
I am not going to any track days anymore this season so I winterized the bike and left it lifted on the stands. About a month passed and out of curiosity i decided to check rear brake. it was not there.
obviously the reservoir was not the problem to start with. now the only components left are MC and the caliper. The line can't be the problem as there is no leaks around banjo bolts.
what do folks think, is it MC or caliper?
