WTF is up with my rear brakes...

[DavidofColorado]

I have to pump them when I am on the bike but when I get off it I don't need to anymore. I bled them and I checked the fluid I even checked for a kinked line but I can't see why its needed pumped to work when there is weight on it?
They have always been like this.

You either have a slightly warped rear rotor or a bad right side wheel bearing. Either one can cause the pads to be pushed back while riding, necessitating an extra pump or 2 to get the pads back in contact with the rotor.

Thanks. I will check these and get back to you.
