My M105 is a temp M103

[DUG]

There is so much wrong with the parking brakes and the service brakes of my M105 that we just pulled the bed to get at everything easier. Came off easily with a highlift jack and four saw horses.

I've tried searching but does anyone know the size or have a source for M105 wheel cylinders or kits?

If the previous thread I have read is correct, they are the same as a deuce.

I have everything apart and these wheel cylinders don't seem to be the same as a deuce.

Where do I find rebuild kits or new wheel cylinders????

 

[DUG]

The wheel cylinder off my M105 is smaller than the deuce wheel cylinders.

It has a part number of Wagner FD10122 on it. I pulled up one thread from 2006 where someone was searching that part number, but no conclusion. I guess I'll take it to NAPA and see what they say.

Wheel cylinders are usually in icrements of 1/8th inch. You can replace the cups and possibly the dust seals at Napa, especially if you get a good counter man. Bring all of the parts in to compare.

The "cups" (or pistons as they taught us in the Navy) are two piece. Haven't seen any like that before. I'll see what the Napa guy says.

Nope, those ain't it.

Change out the whole cylinder. They are probably the same as the old GMC M 211. They were two piece, as I remember. If they cost too much, or its too hard to do, just buy another trailer. But the bore size, is everything, on those cylinders.

Bad thing is stuff on west coast is way more expensive than east coast generally.

Good thing about the west coast is all the sunshine.

Erik's has the wheel cylinders for 33 dollars. Too bad it takes four of them. If I can't find rebuild kits I might go that way.

They actually just look gunked up. No rust or pitting. Once I get everything cleaned up I'll know more.

Only source I see on-line is Saturn. According to the NSN the brake cylinders for the A1 trailers are the same as the M35 Series.
If you find a NAPA number please post it so I can update my records. Thanks, Wayne
