Hello all,
I've been a daily lurker for a long time, but this is probably my first actual thread. I've learned a ton from you guys over the years, but I'm stumped on this one.
I did the R6 fork swap onto my 2006 FZ6. The swap went super smoothly (I still need to fashion some fender tabs), but I can't get the brakes bled. In addition to installing the R6 calipers, I also put on a new set of stainless brake lines. Since there is now a dedicated line for each caliper, there is no loop over the fender to get air stuck in. I've filled the MC with fluid and can't get it to make pressure no matter what I do. I've tried every combination of leaving the bleeders open, closed, and even disconnected the banjo bolts from the calipers to let some fluid gravity drain through the line (it dripped out the right side, but just a few drops came out the left).
I have a lot of experience with track days in my cars, so it's not like I'm new to bleeding brakes. I double checked and all the (new) copper washers are in place also. I'm wondering if it could be the piston seals, or maybe a defective brake line? But still, it seems to me like I'd hear some amount of pressure squiring out the leak, right? The system seems completely tight, but the MC just isn't making any pressure. Is there a hidden bleeder somewhere?
Am I more likely to prime the MC with the cap installed, or leave it off? I've tried both ways.
I also installed new pads and the pistons seemed to slide back really smoothly when I put them in.
I have a Mityvac hand pump *somewhere*, but I can't seem to find it. I hate to go buy another tool I already own (and I always thought was junk anyway), but I'm not sure what else to do at this point. Last night, I left the handlebars turned left and put a zip tie on the lever to hold it open (with the MC cap installed), but it didn't seem to make a difference this morning..
I still have to install the rear stainless steel line and I'm wondering if my process could've avoided this?
Any suggestions? I think it's funny that I was a little nervous about doing the fork mod, but it was something as simple as bleeding the new brakes that actually caused me all the trouble.
Thanks for any help,
Rob
