Hi, I have a 2000 R1 and for the 3rd time now I’ve lost the back brake, basically I went to use it and there was nothing, like it wasn’t even connected, tried pumping it and still nothing, I got to work and tried on my way back home and it was back to normal, now this exact same thing happened 3 times now, I’m pretty sure it’s air in the lines but is there any common places where I could get air leaking in? I’ve looked over the lines and they are in very good conditions and everything seems tight, break fluid was changes a year ago and it’s nice and clean, also I can’t see any fluid leaking out anywhere.

Any thoughts will be appreciated.

Thanks.

you should bleed them.

Thanks for the reply, I’ll give that a go hopefully this weekend.
