Special thanks to Shawn (ak2711c) for sending me the 337 on which this approval was based.
The kit which consists of wheels and brakes cost $896 from Spruce.
I also am buying two solid axles Part No,. 0541124-1 from Hill Acft in ATL -cost $ 223.55 ea. (See Solid Axle topic).
This forum has really been a great help- super bunch of guys!

Rudy and/or Shawn: if you haven't yet done so,please send a copy of your 337's and STC's to Velvet at HQ. That way others can also benefit from the precedent of previous approvals. I sent in mine some time ago,as have others. I have to believe that there are quite a few approved 337's on file for 180 gear legs and/or double-puck Clevelands. If a member needs one, I would suggest that you ask Velvet for copies of all of them. The wording,etc may vary enough so that if your friendly (?) FAA inspector doesn't like one,another may suit him better,as a model for your own 337. Or the fact that you have documentation of multiple previous approvals (as opposed to just one) may make it easier for him to approve your installation.

I'm sending the 337's to Velvet. I really appreciate everyone's help in getting the field approval, especially Shawn who sent me his 337. Many thanks !
I installed the new double-puck brakes as well as the solid axles (new ones). It was Parker Haniffin (Cleveland) Kit No. 199-62. I love the new brakes !
George is correct (as usual) in his message about conditioning the new brakes.
The kit had the following instructions for conditioning the brakes:
(These instructions were meant for the 180/185/206 for which the kit is STC'd but they should also apply to our 170's):
Set power to 1700 rpm and apply enough brakes to taxi at 5-10 mph for about 1500 ft. Then allow the brakes to cool for 15 minutes. (Taxiing for takeoff and flying works well). If that doesn't do the trick, you can repeat the procedure any time. The idea is to put a glaze on the brake linings, which is counter-intuitive to me but it works !

So Rudy,did you install the w&b on your stock (lady-leg) gear,or did you install 180 gear?
After much thought,I would advise anyone wanting to install 180 gear to consider the earlier model gear legs,they have less forward rake than the later ones. I don't know how they measure up compared to stock 170 legs.
But the farther ahead of CG the main gear is,the less directionally stable the airplane will be on the ground. On the positive side,the less likely it'll be to nose over from overly enthusiastic braking.

Eric, yes I installed the big brakes on my standard "lady legs" gear.
I haven't noticed any tendency to nose over ! The brakes feel just as they should- effective but not overly so.
