Carbon Disk Assy Pn.134-308

I've got some carbon brake disks here. Does anyone
recognise the part number and if so, do you know
who manufactures them. I need to get them recerted.

My thanks to anyone who replies to this.

Don't recognise that actual P/N but we have a very similar number that comes up as a "disc", and we used Hanley Smith LTD

Thanks for your reply and will check out Hanley Smith.
On the flip side of the disk or disc is:

133-912
CHG C
MRB 89-1206

If I Google 133-912 I find Caterpillar Z disk. The ones
we have can be traced to All Nippon Airways and the
date on the tag is 1992. We are beginning to think
that these might not be for aircraft brakes or if they
are they might have been superceded.

Do you recognize the 133-912 part number?

Almost certainly a Goodrich brake disc (pn sequence 133-xxx, 134-xxx).

134-308 does not seem to be a current production item however.

134-308 is a 747-400 Brake Disc.
But don't get too excited, that particular brake is obsolete.

Might make a nice coffee table?

Thanks for your view on this. I had thought that the disks/discs
were made by Goodrich because of the part number but I was
told by my repairs bod that they had spoken to Goodrich and
they said it was not theirs but now from what you have written
it looks like maybe it just is not currently in their stock.

What you write makes sense, ANA do fly the 747-400.

Can you tell me how you know that part number is for this
a/c and that it is obsolete?

We will need to go back to Goodrich again but if you have
any definite info it will help me a lot.

Appreciate you guys helping me on this.

Goodrich do not trade in individual disks, except steel ones. Carbon brakes are ALWAYS done as exchange heatpacks, and the OEM regards reclaim information as proprietary and will not share it. Your only option if you want to use these disks is to approach one of the Goodrich R&O centers (you can find these from their website) and ask if they will accept them to build you a heatpack. Be prepared for a price that will take your breath away, and that's if they will do it at all since they normally deal only with airlines and will want full trace on any material they re-use.

The P/N you have is listed in the IPC as an "end plate and torque button assy" however it's a superseded P/N (latest is 134-37-x. It's from 747-400 brake P/N 2-1515-2 and the heatpacks (depending on EDL variant) are P/N 537-3 or -4

Thumbs up Carbon Disk Assy Pn.134-308

Edgar Jessop

Many thanks for your detailed reply. I think we have finally gotten
what I was looking for now. I will still have to try and get something
in writing from Goodrich, if at all possible. These are too valuable to
turn into coffee tables, if it is at all possible to avoid it but it doesn't
look too hopeful.

Actually we are an airline and used to fly the 747-200 but not any
longer. The "end plate and torque button assy," thanks for the
correct description came from a job lot and we have been trying
to figure out what exactly they were and what brakes they
belonged to.

You all have been a great help.
Cheers
