Default Beringer and Grove Gear

I'm building an RV-8. I have Grove aerodynamic gear with the internal "gundrill' line for brake fluid. I also ordered the Beringer wheels, tires, brakes and axle kit from Aircraft Spruce (the one for an RV-8 with Grove gear).
When I test fitted the axle on to the Grove gear the brake caliper partially blocked the brake fluid exist hole at the base of the Grove gear.
Has anybody seen this before? Do I need a different axle?

John----can you post some pics of your install? Having talked with Viviane at Beringer US several times on another RV aircraft project, I was told the calipers mount 90* to the ground, similar to a Grove install. Perhaps the mounting bracket is off centered. See if you can post a pic so we can see whats going on here.

I have no idea how many RV8's are using their brakes, much less the gundrilled gear legs.
I used Photobucket to upload some a few weeks ago. Was pretty easy.

OK. I think I figured out the photo posting thanks to a post on VAF with instructions...this is a great forum.

Below should be two photos one showing the brake caliper on the Grove gear and the second showing the end view of the axle and brake caliper. The caliper arrived installed on the axle.

The caliper is attached to the axle with four fasteners: two that are countersunk (see the fasteners with the yellow witness stripes in the second photo) and two AN4 bolts that go through the brake caliper to the axle and gear leg.

The two fasteners in the second photo with the yellow 'witness' stripes attach the brake caliper to the axle only - not the gear leg.

I think that I need to remove the two fasteners with the witness stripes. This will allow me to move the caliper to a position that is 90 degrees to the ground but will not allow me to re-install the two counter sunk fasteners (i.e. two of the AN4 bolts will have to carry the load of the wheel/tire/brake combination). Assuming the max brake energy is 120K ft-lbs the max shear in the two AN4 bolts would still be below 50ksi - well below the 75ksi max.

Thoughts? Comments? What abouts...?

Thanks
John

hope this picture posting thing works...
