I pulled the lever on my hayes 9 without the front wheel in-stupid. I then pried the pads back apart and noticed some fluid coming out the brake lever housing. This might have been water being pushed out by air pressure (dont know how hydros work) as bike was wet. I then put wheel on and tried it out-brake lever now had very little freeplay but still seemed to work. Do I need bleed the brakes to get it all good again?
