Hi everyone.

Just registered to Yotatech. Been lurking for a while cause this is a great place to find info on my truck. However i couldn't find the answer to my problem by searching.

I'm replacing the brake rotors on my 1991 V6 4runner and everything went fine until i tried to separate the rotor from the hub. Removed the 6 bolts but it's still stuck.

So should it come off by just removing the bolts or is there something else to do? I've read the FSM but couldn't figure it out. Is it just rust and some penetrating oil will help or what?

Thanks,

Wls

 

Hey there, Yeah once you take those 6 bolts out it should come out with a lil' pounding from the hammer. What I like to do if I have a bench vice is open the vice right up, set the rotor ends on both sides of the vice but DON'T tighten it. And take you hammer to it and with a little force it will pop out and fall to the center of th vice instead of falling to the ground or something. New rotor should just slide right on. The reason why it gets stuck like the is because of a little bit a rust and corrosion. MAKE SURE when you are puting those 6 bolts from rotor to hub, Torque them to around 80 Ft/Lbs. Too loose it will warp the rotor easily or fall off, too tight and it could either break off or distort it. I hope this helped you Bud.

 

Yep. In the past, I've also used a chisel as a sort of wedge to separate the the two (don't use this technique between the mating surfaces where the rotor directly contacts the spindle, I think there are spaces between). Before you put the new rotor on, make sure you clean the mating surfaces of any rust (wire brush or rough sandpaper work well) and put a light coat of anti-seize on to prevent it from sticking as badly in the future.

 

Thanks very much.

That's what i was thinking but thought i'd better ask first. The salt that they spread on the highways over here causes the "little" rust problem. Worked for over an hour to get one steering spindle bolt out...
