(Chatty Woman Warning...) I have a 1986 EN454, which I used to really ride the heck out of... that is until the day my son took it out and wrecked the front end. It took two new forks, and a bunch on non-critical dodads to get it road worthy again. However, I cannot get the front brakes to stabilize. I have bled them in a foolproof way. I hook up a squeeze bottle to the caliper filled with clean brake fluid. The bottle is at the same height as the master cylinder. I open the caliper and pump fluid back and forth until no more bubbles come out of either side. This method allows me to flush the line back and forth until no more bubbles come out. When I close the bleeder, I get a good grab on the brakes, until I roll the wheel, then the grip is lost. I can pump it twice, and the grip comes back, until I roll it again, and the pressure is lost. It holds pressure until I roll the front wheel, then it has to be pumped a cou[ple times again to restore pressure. There are no leaks, and I have tried and retried bleeding for many months now. (I have a CB750 to ride too.) I think I have an idea about what the problem is, and I need your advice. When I drive it and pump the the brake to grab, it feels like there is a wobble in the brake disk. Could this wobble be causing the brake pads to spread too far, requiring me to have to pump them closed again? If so, can a disk be flattened, or do I have to buy new or replacement? If this is the problem, is it also possible that the wheel is out of true? I can't imagine that the hub can be bent... it's an alloy wheel.... can it? Thanks guys. I appreciate your advice.
