Rotor thickness ?
 

Is there an easy way to tell what rotors my truck has without taking off the wheel to measure?... its either the 1" or the 1.25".... my vin says it is the 6001-7000 Hydraulic brake system... don't know if that helps... Thanks!

No. Take the wheel off.

Well, I'm 2.5 hours away from the truck, hoping to order rotors while im in city... guess I'm going to have to wait another day.. thanks

A little more detail on your truck would be nice, but based on your user name and your question I'm going to assume you have an '86 C10 pickup.

Here's the brake system release chart for an '87 but an '86 should be the same.

This indicates for C10s with a GVW of 6100 and up get the 1.25" rotor. If you still have the SPID label it may show a JB5 brake system.
