You will get some drag and might be tricky to see visually. I've never done this, but I suppose that once brakes are installed/bled that you could try feeler gage between pad and disc to see if that one side is not retracting as much as the rest? It would have to be a super-thin feeler.



Over-analyzing a bit: i see a couple of blems on the OD of a couple pistons in that pic, but hard to tell if nicks or just lighting/dust/etc... The piston OD should be flawless. If you can feel any defects with a fingernail: replace.



I'm not sure about the bleeder for the ABS bikes; never had to deal with one of those systems before & not looking forward to it. :)


Nothing on the outside of the pistons. The inside has some minor scratches but the surface in contact with the seals and caliper bores is absolutely perfect to the touch.

Yes after I reinstalled everything all 4 pistons move out equally when I pull the lever. Nothing snags and itís perfect.
But... Iím still feeling that drag on the wheel when I spin it manually.
Guess Iíll be sure tomorrow when I test it on the road.

ABS was bled itís no big deal. I used the nipple on the master cylinder and a few bubbles came out. Nothing much. No more bubbles the second time around.

Will ride to work tomorrow and update.

Thanks again!

Drag is normal. The Nissins drag way more than the Brembos, but I still don't get much more than a couple rotations when I spin the front wheel.

Happy to report that the problem has been solved.

Went on the same test ride, first with no front brake use whatsoever. Both rotors ice cold.
On way back used normally and both rotors heat up as usual.

Brake feel is amazing and a major improvement.

Brake pad replacement due next week.

Thanks for the input and I hope this helps someone with the same problem.

Cheers!

Glad you got it fixed! Sometimes they just need a bit more TLC; sounds like the second round of thorough cleaning did it. Pays to be very thorough when it comes to brakes. Jealous that you're riding; snow & ice on the ground here. :(
