Hayes nines disc brakes - is it just me???

[CAB]

My Cannondale f600 came with a set of these disc brakes, i take my wheels of when i store the bike which seems to mean that i have to constantly adjust the brakes to stop the disks rubbing and to stop the screeching....

So my question is:
- is this par for the course when it comes to discs or
- are these brakes just cr@p and do i simply need to throw money at the problem!!

Thanks in advance!

It's normal to have some rubbing with any disc brake, the screeching may be due to oil contamination from riding in the wet (oil floats on the surface of some puddles), they aren't broken in yet or the rotor is slightly warped/not parallel all the way around. Try cleaning the rotors and pads with rubbing alcohol, if the screeching persists then try new pads.

I have a set of old (1998) Hayes disc brakes and they are fantastic once you get them bled properly, I had to reverse bleed mine from the lever to get all of the air out.

My GF's 2005 Orange P7 came with these, and I think they rock.
Ok, she doesn't off-road or seriously cane the bike but they've been top-notch.

I've had a set of these for three years - fit and forget job - no probs.

i have never had any hayes, because my friend who has a bike shop, is not keen on them at all, you can have a set which is fine and be lucky or more likely they are troublesome and require reg bleeding,

but i have had hope c2 for years, they are cool and my more recent hope moto v2 are really good, i totally recommend, however saw the new shimano xt discs the other day, wow, they are good.

I've got Hayes Nines, I've found them very easy to set up (undo caliper, squeeze lever, tighten back up) this centers them without rubbing 90% of the time. This is with 160mm rotors, it can be a lot more of a pain if you have bigger rotors.

Make sure you wheel is perfectly central each time you refit it and it should be fine.

Overall they seem a good brake, I work in a bike shop and rarely see problems with them.

A tip I read on one of the mountainbiking forums (probably STW) for stopping brakes from really screaming: try taking a file to the rotor and rounding off the outer edges of it. It made a big difference to my Juicy 5's.

thanks guys

my take on this is that the pads just seem to run too close to the disc. May have to see whether i can reset by

undo caliper, squeeze lever, tighten back up

if not there is the rubbing alcohol or the file...... bloody disks!!

thanks again guys

A bit of wear might stop the noise, my Avid J5s were noisy at first but now are much quieter although the rear does still squeal a little when on gently but it has had less load/use than the front, suppose using them does the same as filing the edge of the disc over time?

To be honest it is only really annonying when im knackered and i get convinced that they are sapping valuable energy!!!

Next question - how to retro fit regular brakes!!! ;-)
