Hayes HFX9 info

Hi all, I bought a set of brand new in box Hayes HFX9 V8's off ebay not long
ago (yeah I know), they arrived last night and I installed em.

They feel all wrong. First off the front brake lever has heaps more travel
than my other set of V8's on my other bike, and when it finally engages, it
doesn't have as much power as the other bike.

The rears hardly engage at all and you can feel the piston in the brake
lever bottom out (is that bad for seals?)

Is this a good indication that they need re-oiling and a bleed???

I've never had empty hydraulic brakes before, only working ones so I dunno
whats going on...

Cheers Dre

Yeah, a good bleed and re-centering everything would do wonders.

Sounds like they need bleeding. I just bled mine a couple of hours ago and
finaly got it right after more attempts than I'll admit to. HFX9s work
reasonably well when they're setup right but they are notoriously difficult
to get right.
I tried to get by without the bleed kit but until I managed to find/make all
the right size hoses/connectors I'd wasted a lot of time.

Nice, thats what I was hoping. I've never had new hydro's that needed
bleeding from the factory so dunno how they feel
