Bicycle Mechanics - Hope brakes - I have tried everything, now what?

I have a Hope Enduro Pro (4 piston) front brake with an 8" rotor on my DiamondBack XSL Pro bike. Yes, this is my XC bike, but I love going overkill on braking power! Anyway, the thing squeals and squeeks like a raped pig. Here's what I have done to try to quiet it down:

* sanded stock pads
* replaced stock pads with EBC gold pads (couldn't get green at the time)
* worked pistons bank and forth (pumped brake and pushed pistons back in with a 10mm wrench trying to get them to push evenly - did help a little)
* sanded EBC pads
* sanded back of EBC pads to help them contact piston better
* filed paint off the caliper mounting tabs on my 02 Z1 FR fork
* cleaned rotor with rubbing alcohol
* lightly sanded rotor with steel wool

All of those attempts usually helped remove the noise for a few miles, but it was back squealing as loud as always by the 2nd ride after any attempt to quiet it down. I have emailed Hope with everything I've done, and they couldn't suggest to do anything else. What else can I try? I'm going crazy here...

Do you have a 20mm thraxle fork? If not it may be from the one forkleg deflectuing and cause some sort of vibration in thr contack between the pad and the rotor.

No, I'm running a standard QR. You may have a very valid point there, but I'm not sure, tho... I have a friend who had the Hope minis on a 01 Z3 FR fork, and they had the same problems. I did everything to his brakes that I did to mine, and they squealed also. :confused:

From what I have heard (literally) they squeel. My buddy owns a set and they squeel. I have heard of very few people getting the squeel to go away for any length of time and those people are usually on forums.

Is the power effected at all? If not why worry about them squealing?

I've had the same problems with Hayes for a short while.

Power is fine.. still stops great.

I guess I'll just keep putting up with the noise.

I run the M4's. They are the new version. Hopes are know for squealing. Also, EBC gold pads use a high content of metal so it will cause it to squeal also. The EBC reds are a softer compound but will stop faster. The green won't have the stoping power of the red but they will last longer. Both the red and the green will squeal less then the stock or the gold.
But hopes are Hopes and there will always be some squealing.

My wife and I have been running hopes for a year now and the noise is just some thing you get used to.
