Hi all
Went to assemble the calipers today and noticed that the brake pad plate
(the one that floats) is up against the caliper bracket. It is in

with the disk but as soon as there is some wear on the pads, the piston

eventually bend the plate. Has there been any trouble with the calipers
around the serial numbers of 637? It is not a Matco system. The only way
to use what is here is to put spacers between the axle and the caliper
bracket which would the bracket farther inside the wheel assembly.

You are talking the JDM three piece wheel correct?? I'll go have a look at
the spare set I have in the shop to figure out what you are talking about.
Sounds to me like you have something together backwards.

It's the three piece wheel and is impossible to assemble any different

the way I have it as far as I can see. I've built a few of these setups

other aircraft and know the importance of the spacing of the caliper

or the torque plate as it is known outside the Murphy world. Murphy wants

picture and will replace which tells me there maybe a few caliper brackets
out there that are possibly defective. The floating pressure plate

is right up against the caliper bracket.

Guess I'd need a picture too to help you. Basically the entire caliper unit
slides on the pins so no matter which pad wears they both self center.
There
is problems putting them on the bungee style gear if you don't relieve the
drag brace gusset to clear the caliper pin nuts so they can slide. Probably
not an issue since I figure you are putting these on spring gear?

Yes, from what u described it would work as is but as soon as the floating
pad began to wear, the floating plate is already against the torque plate
and then the piston would eventually bend it. There had to be a distance
from the floating plate and torque plate equal to or just less than the
thickness of the pad itself. Computor is slow and am waiting for one of

boy's girlfriends to email the pics she took this evening. I'll try and
post them or send them to you at Irish Field. Thanks for the effort,

Steve..got your pictures and what appears to be missing is MAM used to ship
a .063 (or slightly wider - I eyeballed it) washer that fit between the
torque plate and the axle attach flange (either that or I made it myself
for
Howard's in 1996 but highly unlikey). This spaces the torque plate in
towards the wheel and almost aligns the disk with the torque plate edge.
The
better fix would be to throw the axle in a lathe and take about .080 (or a
match value for your offset problem) off the inner bearing stop on the axle
and then it would line up perfectly. Would be real easy for MAM to change
their CNC program or measurements as well to make them all correctly in the
future.

Thanks Wayne
Was on the phone with Murphy and they said it is the way it's suppose to

and will warranty any future problem. Said they just changed a set of

on an Elite and the wear was even. I will make a 1/8 spacer and put

the torque plate and the axle as I don't have a lathe but sure would love

have one! Would u mind if I sent them a copy of the message u sent me?
Really don't know what it would be worth but u hit the nail on the head as
to what I was trying to explain to them. Thanks for ur great support

Sorry for the delay on this, but I am always about 10 to 20 digests
behind. I had this same problem. When I was in Chilliwak last June I
talked to Robin about it and the solution we came up with is this.

The wheel needs to be further outboard from the caliper mounting plate.
Robin provided a 4130 tube that just fits over the axle. I cut a small
piece off this tube (about 3/16" to 1/4" long) and put this on the axle
before mounting the wheel. This provides room for the caliper to move as
the brake pad wears.
