Hayes Nine pad replacement - Help

LBS used hayes pads, but they would not sit right. The pads rubbed so bad that the wheel would not spin freely. They tried a generic brand pad...and the same result.

When comparing the original pad to the new ones, it appears the non-braking surface material is thicker, and the slot in the middle is not as deep.

All pads that were tried are compatible with hydraulics, so I know they can be used.

Is it possible that the screw in the lever assembly needs to be backed out? Or is a bleed job necessary?

The LBS is stumped because they have never seen this problem on other Hayes models. They usually just pop them in.

Any advice?
Thanks.

Step 1: never trust that LBS, they are scary clueless.

Step 2: download Hayes manual which tells you how to reset the piston pisition

Step 3: what? you havent downloaded the manual yet? get it here

Step 4: read the FAQ

Step5: are you sure you are installing Hayes pads? not all hydro pads are the same.

hayes pads

positive they are hayes...I saw the package.

The LBS has changed pads for me in the past when I had my Hayes MAG brakes. They never had a problem.

They cannot understand why it is not working.

The question you should ask yourself: Why did I change from mags to Hayes Nines???

Push the piston back and re-pump breaks up
