Front pad replacement

[richierex]

My thinking is: the calipers right and left side are directly connected, if I open the only bleed nipple - on left caliper - and try push pistons in of the right caliper, they should displace fluid out of the open bleed nipple. That's not happening, no fluid coming out apart from small amount just from having nipple open. And pistons won't budge, so there must be blockage between caliper on right side and left one. If I pull the brake lever (with bleed nipple closed ) the pistons on right caliper move outward, so the blockage appears to be acting like a one way valve, which is why I can't even get the old pads back in.
I was hoping to avoid having to take the brakes apart but seems like no choice, and was thinking about replacing hoses anyway. Still don't understand why there isn't a bleed nipple on right caliper instead of that other 'filler adapter'...

How about cracking open the pipe union on the right caliper, if the right pistons then move back and eject fluid from the joint, then its the pipe blocked. Somehow I dont think so, there is something strange going on there. Good luck

Well I ordered new pipes from Motobins, along with a bleed nipple to replace the stupid system on the right caliper, which I was assured you can do. Didn't come in the post today and as Monday is Bank Holiday for Paddy's Day I did what richierex and Smudger suggested and cracked open the banjo bolt. Pistons pushed back in no problem. Opened the bleed screw on the left caliper and pushed those pistons in too, so new pads in. Brake lever feels OK, same as before, don't appear to be any leaks so I'll keep my eye on it. When new pipes arrive I'll replace the old ones anyway, but at least bike's not sitting in the garage glaring moodily at me
