hi there just the other day i was riding and my rear brakes decided that they didn't want to work any more...but if i pump my rear brakes about 7 to 8 time then they will work but i have to do this evey time i go to use them...could somebody tell me wat the problem is nad yes there is brake fluid and yes we bleed the line and re-did the brake fluid so idk what the problem is

do u mean after u pump them 7-8 times they will work for a little bit or just once ,is the pedal just soft or does it go to the floor each time, if u have to pump the brakes like that to just stop sounds like maybe fluid is by passing the piston inside ur master cylinder. are u losing any fluid or the level stayin the same
