M8 Greyhound Brakes

[MikeV]

Hi everyone
I am the second half of the team for The M8 brake project . We have had the cylinders re sleeved but, they did a poor job, we installed all the newly done cylinders and they all leaked. we are in the process of honing and getting the grooves out of the new sleeves from the repair, any Idea where we can get the brake cyl. seals that fit in the older grooved pistons, we are running out of options,
thanks for your help. i will post Pics. Later.

Have you asked on Steel Soldiers forum? There are restorers there who've seen and done just about everything, or will have the only-one-left-in-existence 3rd line shop manual with the exploded views of everything. There is likely a commercial equivalent.

Thankyou for that we will reach out to them.

Hi MikeV,

Did you find some cups for the old pistons? I might have some new ones left here. There is a guy in Belgium who I think still has stock of the NOS ones.

I am not sure of the availability of these kits but a friend rebuilt all of his wheel cylinders using the Raybestos MK37 kits that come with the newer style pistons and cups with it and works great.

Well after careful examination of the wheel cylinders, eleven of the fourteen are damaged, at least four are irreparable. We are now searching for twelve new cylinders. Anybody have a lead on some?
Once we have new ones we'll go with the Raybestos WK-37 piston kit.

Well the saga continues, it appears that Raybestos no longer mages the WK37 kit, and no suppliers have them remaining in stock. I did find a equivalent made by Centeric, 144.80009, but it seems that they are or have stopped production as well. Does anybody know of a suitable replacement for the old GM# 5450435, Raybestos WK37 or the Centric 144.80009. A brake wheel cylinder rebuild kit 1 1/2" bore with cups, pistons and a spring?

Hi Brian,

I got mine from Ross Prince in Australia but I guess Tony’s EBay option is a bit closer to you.
