Guys, I've found out my disc was not perfectly centered in the caliper
The bike was braking perfectly so I didn't notice it before, sorry...
It's not a big problem actually, as the cylinders adapt themselves to the disc, but I'm a bit pissed anyway
I don't know if that's a design error or maybe this is just with my calipers, could you check yours please?

Anyway you can sort this out in 2 ways: either smooth 1-1.5mm the brackets caliper side, or add washers between bracket and fork as I did.
I went for the easy option but it's temporary, I think the other way is better in the long run.




Now it looks centered

[Stanleybobly]

dremel the edge of the bracket round
the fork is round edged and the bracket is 90 degree.

No imho. This is not a job for a dremel.
Use the washer method as Brucaliffo has or preferably have the bracket machined flat and square by whatever the offset difference is off the centre of the disc and centre of the caliper.
Just my tuppence from the fence lads...

Brackets arrived this morning and look very nice. Still waiting for my pro bolts ordered them last week and they have just sent an email confirming despatch today just got to get me some callipers now but am watching some on ebay at the moment. Thanks Steve

[Brucaliffo]

this is the explanation I've got from Carlo, I see he has some good points

The problem is that the fork is made of casted metal, not machine finished and badly painted!!!

When I did the measurements, I averaged measures from three different caponord forks (mine and those of two users) to try to reach an acceptable average.
Then taking into account the fact that the caliper pistons can work well even if not perfectly centered, I've decided for the version you have in your hands.

Too many variables are involved here: forks different from each other for bad manufacturing tolerances, paint which is consumed / detached / cracked with the kilometers, paint thickness different in production, crushed attacks due to mount / unmount of the original calipers, etc... etc... (I have even found no coplanarity between the front and back of the eyelets on the fork! ...)

Aprilia does not have this problem with the original calipers... as they are floating... and even if sometimes very off-centered, nobody objected...

Cheers
Carlo

What brand and type of brake pads are you using for your P4 34/34 brake calipers? I can see that there is a huge difference in price.
