Front brakes issue.

I had the front right fork seal replaced. When I got my bike back the front brakes just sucked. I called the dealer and asked them if they knew what would be causing it and they said to bleed the brakes which I had already done. Of course they say they did nothing wrong. They were perfect before the bike went to the shop.

It works good the first time I use the brakes then goes back to the spongy feeling. Normally these brakes will throw you over the bars as you all know. Now they just suck and take forever to stop.

I've bleed them, replaced all the fluid with new, bleed the mc, and cleaned the pads and rotors. I've bleed the whole system at least 7 times, and like I said they work great the first time I pull the lever, after moving they go back to crap.

Any other suggestions?

There may be some air trapped behind the pucks. Remove the MC cover and sponge up a little fluid, yank the calis, remove the pads and push all the pucks back in as far as they can go. Refit the pads/calipers and pump the pads back onto the disc and hope the lever stays firm. :)

There was another Hyper frt brake issue a while ago referred to as "pump up" but your issue sounds different. With the pump up issue, the brakes would work great first time or so, and then be hard to modulate, as the lever had to be pulled further to the grip before they started to bite. A number of owners felt the seals were too tight around the pucks and would pull them off the rotors too much, and so they lubed them with a rubber/silicone lube and that seemed to help keep the pucks on the rotor for consistent lever action. When your brakes go mushy, are the pads still riding on the rotor? i.e. you should hear a little hissss from the frt brakes when you walk the bike. Good luck. :)
