    Anyone figure out how to use a 180 rotor with Hayes?

    Just wondering if anyone has figured out an adapter, or used an adapter from another MFG to run a 7inch rotor up front with hayes brakes. thanks.

    I dunno. Would the Magura adaptor work?

    I have one that converts the rear from 160 to 180 so maybe it would work up front. If you can find out quickly then I'll mail it to you to try out since I'm not currently using it.
    Let me know quicky cause i'm in mega-pack mode.

    The Magura might work although I think the adapter for the Louise FR bumps it up from 180 to 210 for a 30mm jump. You could contact Jimi to be sure.

    This one would definitely work though...

    If you have an IS mount front fork then use a rear adapter IS to Hayes adapter on the front- it will work. Also I was able to use the Avid cup and cone washers to make alignment of the caliper easier.

    I forgot the Hayes already has an IS adapter so that would be 2 adapters with what I was looking at. You are right. Using a rear 203 IS adapter on the front is easier.

    so what I'm hearing is...

    take the 8 inch adapter for the rear and run it up front, and the 7 inch rotor should work without a problem? or do any other mods/spacing/grinding issues need to be done.


    thanks - GG

    You don't use the 8" rear adapter, you use a 6" rear adapter on the front and then a Avid 185mm rotor (about 7.25") will work. You may also have to use the washer system from the Avids to get the caliper to align correctly.

    thanks

    I may just give that a try this week or next. My fear was the adapter running things too high or low, but it sounds like it may just be a few spacers in either direction. Worth a shot I suppose.

    DOH! Sorry I was confused again. I know the same adapter will give you a 20mm difference from front to rear but brainfarted as to which one is smaller. Magura and I'm sure others make a 180mmx2mm rotor so you don't have to use the Avid 185.

    actually 185 wouldn't be bad

    easier and cheaper to find a 185 rotor than a 180.

    Yup...

    Use the adapters and rotors for an Avíd 185mm. Both Hayez and Avíd calipers are designed to fit directly to a Manitou post mount (well, the Avíd uses the spherical washers, not the Hayez). So, any adaptor for the Avíd will work for the Hayez.

    Even Avíd recommends some Hayez adapters they do not manufacture....

    Let's break it down...

    The caliper barenaked is 74mm PM. You need ONE adapter to fit the caliper to the 51mm IS rear mount. The adapter has 74mm PM on one side and 51mm IS on the other.

    NOTE ... the front and rear adapters are different (even when they both fit a 74mm PM to 51mm IS)

    I hope you can help me VT no 1 2 or 3, I followed your suggestion using the rear hayes adapter for 6" and it works fine perfectly...i used a 180mm 2mm thick aztec rotor...they are exactly fits with no washer at all...i just cant fugure.. out theres friction between the pad and rotor maybe because the 2mm is too thick or do i just need to adjust the caliper alighment ...what did you do or you dont have this problem with avid? i'll try again tonight to align it to the claiper i hope i'll work...o well....your suggestion are welcome. thanks

    EASY!...for a 185 mm rotor (not 180 mm, not "7 inch"). Most - if not all - Hayes calipers are 74 mm post mount and use a bolt-on mount for IS.

    Just buy an Avid 185 mm mount and the 185 mm rotor of your choice and bolt them on.
    DONE!

    180mm is 7.092 inches....185mm is 7.289..nway i already bought the 180mm and rear hayes..adapter...it fits well....i just cant figure out how to take away the dragging or rubbing of rotor and the pad....should i adjust the pad...but its self adjusting right? is there a technic to properly align the rotor to the caliper? i tried the hayes instruction to squeeze it then torque but still theres little dragging...if i leave it like that, will it affect the performance of the brake? or any affect on my riding? or do i need to break-in the rotor with the pad so it will fit properly..thanks for the suggestion.

    Have you tried pushing the pistions back into the caliper to allow them to adjust to the thicker rotor? Also I don't center the caliper over the rotor- I center it over the warps in the rotor. I do this by using automotive feeler gauges, spining the wheel till I find the most warped section and move the wheel so the most warped section is in the caliper, put about a .005 to .010 feeler gauge between the rotor and caliper, sqeeze the brake lever to hold everything in place and torque down the caliper mounting bolts. I may have to repeat the process several times using different thickness of feeler gauge till I get things right. If you have put in new pads you may not beable to eliminate the rubbing till the pads wear a bit to get enough clearance.

    Shiggy is correct - Use the Avid Adaptors. I run a 203mm front and 185mm rear using Hayes brakes, Avid Mounts and Hope Rotors.

    Avid Adaptors are cheaper than the Hayes also!
