Default Rear rotor stuck/seized

Attempted to replace all four rotors and pads today. Got the fronts done. The backs were not so easy.

So I'm not sure their stock or just cheap rotors form the previous owner but the rears do not have the 8mm small holes to help remove them.

I made sure the hand brake was down, I even clicked the adjuster all the way down, used PB blaster and hit the rotor with a hammer.

It wouldn't budge.

Considering doing something like this on my next attempt:

Thoughts?

Well considering he's replacing the rotors, I wouldn't worry about using a dead blow hammer to lessen damage, unless there's another reason you suggest using one. The vibrations imparted by a metal hammer may help break it loose better.

Make sure your emergency brake isn't on.


EDIT: it helps if I read the whole post first. Dead blow.

Just man up and hit the rotor with a mini sledge with all ya got. I like to hit it right at the corner of the hub.

The only thing you have to watch out for is that you don't hit the lug nut studs you will screw up the threads.

The reason they stick is a layer of rust in between the hub and the rotor fuses the two together. It's hard to swing from the inside of the car out so just swing from the outside of the car in. Don't be afraid sometimes you gotta show em who's boss.

Work smarter, not harder. Use a long bolt and a nut into the caliper bracket attachment points (with the caliper/bracket removed) to press the rotor off.

We would not worry about employing a dead blow hammer to reduce damage unless there exists another reason you suggest using one. The vibrations imparted by a metal hammer will help break it reduce better.

and if the rotor chips or shatters and causes collateral dammage such as a cut brake line or abs harness....or maybe your face???
what then???

a TRUE professional would consider this and be smart about it and not let that possibility happen in the first place

also...the vibration that you non-professionals think may be good....may also kill other associated parts and cause other damage

and ive been a licensed A&P mechanic since 1984...so i guess i dont know anything about this

Didn't know we were spouting off certifications... Recertified ASE Master tech, Toyota factory trained, roughly 3000 brake jobs and alignments under my belt, just to start. Never damaged an abs sensor or brake line in the process. I can only imagine the life you must have working around the .002% chance of come thing that might, possibly, could maybe happen if things go bad. Guess I better not go to work tomorrow, my impact might explode and decapitate a nearby infant.
