I've developed some weird issue this year and looking for recommendations.
So I have a low mileage K7 750, about 4,000 miles
Didn't get ridden last year because of extensive OCONUS travel.
Fluid is as clean as it gets.
So the issue is; When riding I can use the front brakes a few times over the span of say 1/2 mile and then the front brakes will not disengage. They'll slowly start gripping until its just locked onto the rotor. I'm then forced to bleed a little bit of the brakes to release pressure. No bubbles.
Saturday and then this morning I took the calipers off to inspect. Nothing popping out.
From what i can decipher the fluid is coming down the line when engaging, but is not making its way back up when the handle is released. I had no issues taking the pads out on the left side and moving the pistons back and forth, I was able to do the same on the right side. But at the same time I can't seem to get all the pistons to move back in, in order to place the pads back in.
So I'm speculating that their may be an issue some where from the caliper going back up the line to the handle.
I'm a little stumped at this moment as to the issue or next steps.
Other facts, I did replace the stock handles with aftermarket units.
