New C50 Owner

Nobody makes/sells the gm 15x5 brake shoes anymore. I've called several places over the past year and no one could help. I plan on sending my rear shoes to this local company to be relined.

Centric brakes makes 14x2 shoes for the front and dorman still makes all the rubber brake lines. Raybestos still makes wheel cylinders (although made in China) and can order them from Rock auto. If you need any help with part numbers just let me know.

I got Centrix wheel cylinders for the back from Rock Auto, but have not installed them, yet. Our local Fleet Pride said to bring the shoes in. They felt sure they might have what I needed, although Airdirect is the third person to tell me they clean them, all the time, with no issues. I think I will try that first.
Right now, my biggest concern is the inner wheel seal.

3974846 is the original GM part number for 1969 c50 with 2 speed rear axle

370106A is the updated timken/national/federal part number


Gmpartswiki.com will be your best friend after this

Dorman H38908 is the brake hose from master cylinder to the frame for my 67 and It looks about the same as your 69.

I'm also trying to figure out what rear axle I have. The SPID says it's a T150, but the casting numbers Google a T170.
BTW, what does SPID stand for? Sticker Placed In Dash???

Final update. Got new wheel cylinders installed, new brake lines, cleaned the brake shoes with Brakleen as Airdirect suggested and everything worked perfectly.
After hounding the guy who said he would do the modifications for me for 7 months, I took the truck to two different shops to get estimates. WAY out of my price range. So, with a touch of bitterness, I sold the truck.

I no longer own a pre-'72 truck!
