...and am collecting bits and pieces to put them together. I have the same calipers on my '07, but they were installed by the p/o so I have a couple of questions:

-the flebay calipers($50 shipped) have one missing and one broken dust shield. Looking at the "open" design I can't see any real benefit to a dust shield. Leave them off, or hunt down another pair?

-The oem '15 brake lines are a smaller diameter than the ones attached to the used calipers('03 750 gsxr). I am assuming that unless I change the Master and all the lines to it(which I really don't want to do) I should just use my own existing brake lines?

-I am going to re-build the 4 pots and found a pretty good sticky:
How to: Overhaul Tokico six-pot callipers
it's for 6 pots, but the 4 pots will be almost identical.

Prices on the re-build kit are kinda nuts....anyone with a good source post it up!

I'm in no hurry, so I am going to take a bunch of photo's and try and put together our own 4 pot sticky(if it's worthy of course)

I went with the OEM kits for rebuilding the calipers. Mine were off a salvage bike that was over 10 years old and had sat around for a few years. I did reuse my brake lines and they work well enough.

If I had to do over I would buy a set of calipers from a salvage bike that were not too old. The cost of the rebuild kit is ridiculous. Just install the salvage units and you will be flushing them anyway when finishing up the install.

Yes a pack of O-rings for $40(PER SIDE) is hard to understand. I have considered hooking them up, bleeding them and running the pistons out/back in a few times to see if any are sticky. Don't fix it if it ain't broke?

If they've been sitting it might be a good idea to take them apart, hone the cylinders lightly then clean thoroughly.
But if the o-rings are good then you're done.

But the little voice goes...."hey man those things are 14 year old...just sayin"...........

Hmmm, a disassemble clean and inspect does not sound too bad.

If I took them apart, I would NOT put it back together without new sealing rings at least. Just sayin'.....it is your brakes remember!

Hola, my 04 Wee isn't exhibiting any brake problems and I ain't changed the Brake fluid yet.
Should an item sitting on the shelf be necessarily bad?
Oh, I've successfully taken a stuck set of Honda brakes apart, cleaned and honed and reassembled without new parts.
It can be done.

Yes, it can be done. I have honed my share of wheel cylinders on cars and truck and put stuff back in that came out. But it was when I didn't have any money for new parts or couldn't get to the store to get them. It was also on a car or truck where, well back then brakes were not all that good anyway and a failure usually meant you had 3 other brakes. Maybe two? :grin2:

New parts sitting on a shelf is different from used parts sitting with fluid in them. My experience with putting used parts back in is that it is a temporary fix. I have had them leak a bit of course, but also get to where they don't return properly. Which is even worse on disc brakes.

Not saying not to do it. Just be honest with yourself when you inspect those sealing rings. These are likely rectangular shaped, not round 0-ring type seals. Meaning if the edge isn't in perfect condition they are not in good shape.

Exactly - you can see a bad o-ring.
Bend it - if it breaks or cracks it's done for.
Flat spots - done for.
Round and flexible - GTG

Where they go bad is
1 - crap settling on the o-ring
2 - corrosion made pits.
3 - o-rings deformed or non-pliant

1 & 2 can be handled by so cleaning and honing - the orings can be damaged when the piston moves. But if the orings are still viable I'd say go for it given the cost.
3 - you need a kit but cleaning and honing is still advised.

I guess the owners of Oneida have lost their minds, here was their response to my shipping inquiry:

"Shipping options are available during check out,USPS and UPS methods are offered. All orders ship through a tracked service and insured.

Thanks

There is reason dust covers are there. without them calipers sooner or later gone get seized. and after that if you keep going you might be eventually replacing rotors. do your math

Honest question here though....the oem calipers are a closed back design...no dust shield. The 4 pot's are completely open with a thin metal shield that leaves a big gap all the way around. Now, with the orientation of all calipers(hanging off the rear of the rotor at a 30 degree-ish angle) just what is the dust shield protecting the top/back side of the pads from? Water/dust/dirt/mud goes right in so the oem style makes sense to me, the 4pot...not so much:


Could it be a heat sink? and if it is how does the closed design cool?
