What size drums?

[jkeaton]

1995 ECSB, I searched for "what size drums", but came up with nothing. I also looked for a "dumb brake question thread" because I'm sure this is common knowledge or has been asked before. I am redoing my brakes and need to know if I have 10" or 11" drums. Z71 package, if that makes any difference. Go easy on me.

It would depend on what rear axle you have its either a 10 bolt or 14 bolt. The 10 would have the smaller drum an the 14 would have the larger drum. If I had a ten bolt layin around id measure the drum for you but ever since exploding it ive only had 14 bolt parts lol

10-bolt axles typically had 10"x2" brakes, 14-bolt SF axles typically had 11"x2.5" brakes.

Only way you'll know is to measure or decode your VIN. If you have the RPO F44 you have the 14SF axle.

So I have 10 bolts holding the diff cover on, so I have a 10 bolt? Which would be the smaller drums.

Correct...10" drums on the 10 bolt rear end

Dang. I was hoping for a big, beefy, gnarly 14 bolt...lol
