I am doing am doing the brakes on my
91 Toyota, I did them about 2 years ago, and they were wearing bad from the getgo, any way I am going to replace the calipers, pads and the front brake hoses, looks like I have to replace one of the rotors, will a rotor from a 85 runner work?







Rotor on the 91

Bad uneven wear

Rotor from a 85 4 runner

 

Solid axles brake rotors won’t work on IFS trucks.

also the 85s were non-vented and later models were.

 

That used rotor looks just as bad as the one you're replacing. It may not have the uneven wear but it's so rusty you'd have to resurface it to make it useable. At that point, you might as well just buy a new rotor. You'd have to cut a lot off that rotor before the surface was good again.

muddpigg is right, '85 rotors will not fit, but the pictured hub and rotor is not from an '85. Solid axle rotors are not vented and the pictured rotor is. Secondly, solid axle hubs have a much larger offset between the wheel mounting surface and the hub mounting surface. It's a fairly common swap to install IFS hubs on SFA spindles to widen the track without using wheel spacers, and that might be what you have.
