Time has come to do the brakes, front and rear, but everywhere I look for pads and shoes asks me if I have 9" or 10" drums and rotors.

How would I go about telling what size my drums and rotors are? I'd prefer not buy a measuring tape if I can help it. And the vin decoder doesnt tell.

Thanks.

So how do I measure these, got a measuring tape I found in the truck.
Do I ust measure the rotor edge to edge, and do I measure the drum from the inside or outside?

I'm getting 11.2"

 

I did my brakes when I 1st got my truck and I do believe they are 10" .Cause when I went to replace the springs in the drum. Autozone accidently gave me 9" spring kit and the springs were tooooo tight and had to take them back for 10". So I would think they may be the same as yours.

 

As far as I remember, the differant size brakes are on the rear, not the front.
I don't know how to measure the rear brake size, but I think it's listed on a sticker under the hood. (?)

 

Your want to measure the inside of the drum. The machine surface. Most likely since you got 11in on the outside you will have 10in.

 

Let me ammend my previous post:
As Crazy said, the 9 or 10 inches is determined by the inside diameter from machined surface to machined surface.
I just don't know what the distance would be as measured from the outside of the drum (ie. not removing the drum).
