Question on front brakes

[mightymouth24]

I have a 2000 s4. I started to put new rotors and pads on the front set of brakes, when I got to the rotor I could'nt get it off.[headbang] . We tried everything short of taking a big sledge hammer to it. It is so rusted on there we could'nt get it off. Does anyone have any tricks or advice, I would appreicate any help. Thanks

take a big sledge hammer to it

[ratty]

I've heard people recommend PB Blaster or similar to loosen them up. Haven't used it myself though.

[quattrotman]

Yup, use a sledge...but once you do, you are committed because your going to screw up that rotor [:D] Maybe try and get a bit of WD-40 in from behind...might help?

heat it up.

[mightymouth24]

Thanks for all the input

[damnthemansam]

if you wanna save the rotors put a piece of wood up against it and hit that with the hammer

The rotor is rusted onto the hub?

Or you can't get the rotor out from behind the caliper carrier?

I think the hub offset on the rotor is such that you need to loosen the caliper carrier prior to removing the rotor (best to remove the lower bolt carrier bolt and rotate the carrier a bit).

Remove the carrier and heat the rotor. It will take considerable heat due to the rotor's great mass.
