Mine has been like this since I bought it with 1300 hours and it's no worse now with 2500+ hours. I have inspected them and found they look fine; it does not take mush clearance to give you some play. Snug the bolt so it?s not sloppy loose and carry on;)

Remember that this is a fastener that's loaded in shear, not tension. If the hole is elongated enough to show movement of the assembly, tightening the bolt will only deform the bracket and mask the real problem. Properly installed, the nut is only there to keep the bolt from falling out.

All that said, plenty of airplanes are out there with sloppy bolt holes and aren't going off the end of the runway... So cranking down on the nut might work fine - it just isn't the right way to do it.

Just trying to save Tim fixing something that's not broke.

You are right however snugging the bolt does not just mask the problem, snugging the bolt does deform the brake anchor slightly causing it to hold to the axel so the assembly is not vibrating loose and slows its wear. It?s going to be like this on most of these airplanes that are flown, you can wear it out fixing it or you can pick your battles and go flying.

Thanks
 
Thanks folks. Put it up on the stands today. Play going through the axel was quite a bit less than through the flange. The A&P wants to replace the brake flange / bracket. So will fly it until I get that in and then do it with an oil change most likely.

One thing the tech at Vans mentioned was, ensure the different sized washers are stacked correctly so that the bolt is tightened correctly.

Appreciate all the help,
Tim
