Rear caliper removal - broken bolt heads HELP!

Rear caliper removal - broken bolt heads HELP!
Hi all, I am lowering the subframe and differential to replace the hard fuel lines. I have everything ready except the rear caliper and brake lines. I broke the 3 bolt heads on one caliper and two on the other, the 3rd bolt I can't even get off it is on there good. How do I remove the brake line so that I can just leave the caliper on there so that I can lower the entire subframe and get at those broken bolt heads more easily. No idea how I am going to fix that mess either...any suggestions?

If you only had loosened the ONE 12mm bolt on the caliper,you pop the caliper UP off the rotor,and it would have slid off the glide pin on the bracket.
You broke the 14mm caliper bracket bolts..
No real way to get the brakes off now,Unless you grind off the front of the bracket,then take the rotor off..
once that is done you can grind the bracket off.(or it should fall off.The bolts are just through the assembly and thread into the bracket.
OH,you are gonna need room to do this so you may as well just take the Flex line off the brakes.
That way the whole diff will fall now anyways.

With the bolt heads broken, the caliper should come off now, shouldn't it? The bolts may be seized in the holes slightly, but with a few hits from a hammer, won't they come off?

The bracket won't come off Unless the rotor is off.The bolt gets hung up in the spindle assembly's hole that the bolt goes through.
Now,to rectify the previous Post that I had above:
IF you take the 2 screws out of the rotor you "MAY" be able to get that rotor and bracket to pop off as "one"..That is IF the bracket's bolts are not seized in the spindle assemblies holes.
....
I had this happen to me and I cut the crap out of everything to get it off.The bracket bolts were Stuck TIGHT in the spindle assembly and it wouldn't budge until I got at it with a cold chisel and a sledge hammer,
The outcome was getting new brake brackets,and they are only available if you buy the Complete rear brake assembly..(not just the caliper.)

Just slide the caliper off the Bracket!!!
it will dangle loose BUT still be hooked to the car by it's Rubber "flex line"(brake line that goes to the caliper)
TIE the brake caliper to the shock springs so they don't interfere with the dropping of the subframe.
DO you have ABS????

Piece of cake.
Do what the said for the ABS Sensor.
After its out of the way, unscrew the rotor, it will need to come off with the bracket.
Get a can of MAP gas with a torch head, a can of PB Blaster, and a large/long punch. Soak the broken bolts with PB good, then heat slowly, not excessively and hit the bolts out with a punch and hammer. As stated before, they screw into the caliper and only go through the hub.
Just be patient and don't use too too much heat, I think the rear hubs are cast aluminum.

Well I've tried twisting it back and forth to pull it out but it's not budging. I soaked it in Liquid Wrench for a few days prior. Does the sensor wire just pull out regardless if the bolt is in or out of the toe control hub? I would figure that you would undo the bolt then the little plate would pop off with the sensor and wire but it doesn't seem to after trying to pop it off with a flathead screw driver and a hammer after unsuccessfully tring to twist it out. I got the tip of a screwdriver in between and gave a wedge and the plate started to lift (bend) so I stopped before I did anymore damage. What am I doing wrong?

I just read a boat load of stuff on this sensor and it appears to be a real SnotBag to get off.
PB BLASTER is recommended..( I'd use this over Liquid wrench any day).Soaking the **** out of it and turning it side to side is about all they can give ya.Then try pulling it straight out.
.NOTE:..just out of curiosity,would you consider ABS delete??.(then you can cut that wire and drop the subframe.!!!)

I searched : "ABS removal" on here.That is how I got the info.
I assume turn the sender and the plate.
Also,ABS removal would entail getting rid of the Abs Pump in the engnen bay and rerouting some brake lines,so you can look that up to see if that is what you would like to do.

Never fail though Huh?..simple **** turns complicated with these cars..!!!
