    Cant get rear rotors off!! 2005 sts awd

    I've gotten every thing off in regards to changing my brakes, but now i cannot get the rotor to come off of my 2005 sts awd. I've banged on it some to try and loosen it up but it will not budge. I'm not sure if there is some sort of trick to it, but please someone advise me on this situation!

    Is there a small hex bolt holding it on? I've made that mistake ONE time, I'll never do it again...

    I did a brake job earlier this year on a friends car and literally had to soak them in LiquidWrench and beat the crap out of them with a 5# sledge before they came off.

    Sounds like you have everything removed just have a little nature on your hands. Be mindful of the lugs, don't bend them suckers.

    I used a small hand held sledge hammer and kept going until they freed up. Hit all around the pad surface.

    thekid15, The rear brake rotors has a small brake drum built inside the rotor. This is for the E-brake. Back off the adjustment on the back side of the rotor assembly. It should then slide off. But first put some liquid wrench on front side of rotor at the center hub. Danny

    For future reference WD-40 is NOT a penetrant its a lubricant. It is never a substitute for PB Blaster.

    News to me. Mental note made.

    I've used stuff called liquid wrench that works pretty well too.

    Sometime I like to use the blue wrench. For those that don't know what this is a big gas acetylene torch. Danny

    And people wonder why I put anti seize between the rotors and hubs(and rims). Nothing like beating a frozen on rotor or drum off a car.

    When using anti-seize I wear rubber glove. Be careful, the anti-seize will end up on every thing. On my arm, behind my ear, down my pants. Danny

    Penetrating oil=Mouse Milk. It was developed for disassembling turbine engines.

    When pounding around on your car parts it's wise to use a brass hammer so you don't ding them all up.
