    broken hayes nine

    I was riding to day, and went down pretty hard and i think i hit my lever and busted a seal on the piston. I took the caliper apart, applied the brakes, and could see a little bit of air and brake fluding leaking from each side of the piston. After taking every thing apart, i was looking at the seals and they appear fine, but I am assuming i need to get some new ones?

    I'll describe what happens to, incase you have some other input. When i hit the brakes it grabs at the normal point, then it slowly (2-3) seconds looses all of the stoping power, and when the lever is all the way down, there is no preasure.

    If I can get some imput quick that would be great, I need to have it up and running for a race on sunday.

    Thanks guys

    You either have a leak or a bypass in the master cylinder. I really had no idea what you said in the rest of the post. Go to your shop, see if they've got a Hayes small parts kit. Or call around and find somebody that does. Otherwise you're stuck overnighting a brake from an online retailer. If it comes down to that... I wouldn't get another Hayes HFX-9. Atleast go with the Mag.

    I think I'm going to have to get a whole new brake set up. My friend says the lever is screwed (he's had this happen to him) and when i took the caliper apart to replace the piston/seals there were scratchs on it, and i was extra careful not to get any thing on them. Unfortunatly one of our mechanics broke his collar bone, so it may be a little while before some one knowledgeable can have a look at it

    time to start shoppin for a new brake
