A question about Hope brakes!

I recently bought a set of Hope M4 to run in the front. I noticed that the dual pistons on the right side sticked out a lot. I pushed the pistons back and tried to center the caliper so all four pistons would travel the same distance to grab the rotor, but failed. The pistons on the right side still sticked out as before.
A little side note: By left side I mean the pistons closest to the disk mount, and right side I mean the pistons closest to the spokes. And it was bled also.
Very hard to get my camera to focus in on the caliper...


Are they suppose to behave like that?

Can't tell by your pictures. Take it to your LBS.

Do you guys see the pistons pushed out now?
I actually took it to my lbs to get it bled. I asked them about it and they told me to simply push them back (which I did).

Awesome. I get so amused by the simplest of things.

jiiiim, for future reference I find the use of the macro feature on the digital cameras helps a lot with close-up shots like you attempted. I also find that the flash tends to wash out the image using the point-and-shoots, at least from the ones I've used, so I turn the flash off and put the camera on something stationary while taking the shot. Make sure there is enough ambient light, though.

I think there's a slightly elevated chance of sudden catastrophic brake explosion syndrome, but chances are you'll be fine.

I think you're making that up. Right?

That's only with the homebrew brake fluid/pool chemical recipe I think . . . .

Lol, so true. Like my avatar says.. I'm a noobhead
I totally forgot about the up-close feature. I did however figured out the flash and lighting part wooot! go me!
Anyways... as you can see, the pistons on the right side stick out about more or less 2mm even when lever is not depressed, compare to the left pistons which are almost flush with the housing.

I'm just a worrier, that's all... lol
So my new question now is... why are they like that? Thought they were suppose to auto adjust to the center like my Shimano.
