Can not get rear break

You should be able to use a punch on the end of those bolts and tap them out from the other end. the bolts go all the way through the caliper. The bolts have a 3" smooth shaft below the threads that hold the pads in plce. This can become worn or notched and difficult to get the bolt out. You may also try prying on the head or clamping the head of the bolt with vise-grips and tapping it out. I know there is not much room to do this. Good Luck.

did you use a c-clamp to decompress caliper?thats the first step to fixing brakes make sure you pull brake fluid cap to let excess back into reservoir.c-clamp if big enough should fit over assembly then put screw part on front brake shoe and start screwing in!!that should do the trick!!! :) amtnng

If the mounting bolts will not come off,buy a complete rebuilt caliper with mounting bracket and hardware. Check that the hardware contains new mounting bolts.
Cut bolts off with a high speed metal cutting disk and remove caliper.
When installing new caliper always use thread lock on all mounting bolts.
Bleed system with new fresh brake fluid and you are done!
