'72 K2500 Rear Brake Shoe Q? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**special-K** · 09-03-2018, 11:46 AM

I'm getting parts together to get into the rear brakes on the '72 K2500. Been quite a while, but I'd swear it had 12" brakes or at least 12.125 max dia is on the drum, IIRC. I remember going around with it last time. Got wrong shoes first time, tore down, took old in to match up. I am asking because I'm looking online at NAPA and what they list are 11 5/32 x 2 3/4". Does that sound right? Anyone else have one who could tell me?

The 11-5/32" drums are heavy duty, which I only learned here, recently. Never seen them in the wild. Mine are 11", but it is 2WD.

I went through the same thing with mine shortly after I bought it. Pulled the drum to see what I had. I found a 12 x 2.5 All the online parts sellers listed something different. For giggles I looked at C2500s. lo and behold those shoes were what I needed. Wheel cylinders were listed as the same part number for c2500 and K2500. So I went with all parts for the C2500. Exact match to what I had.

This is what I found out on my 71 as well. I ended up making a second trip to the parts store with the worn original in my hand to match, since the K shoe listed was different, and it ended up being the shoe listed for a C2500. The wheel cylinders were the same as well, but they were listed as such.

My NAPA receipt from 2004 is for p/n TS-248, which is shown on NAPA's website as 11 5/32" x 2 3/4". This was for my '72 K20.

The question has come up before and I can't recall any specifics. Next time my drums are off (not for several years, I hope!), I'm gonna measure the damn shoes and write it down. If I remember to!

I was ready to order, but will wait till I tear into it so I can carry a pair of shoes in. I believe the problem here is they list the K/20 HO52 shoes for the K2500 Dana60. The C/20 w/leaf spring wheel cylinders are the same as K/20
