stuck mounting bolt
 

I am doing a brake ob on my 88 260e and the caliper mounting bolts are stuck, I have tried everything and almost broke my rachet by pounding on it with a hammer, do i need a blowtorch, any ticks I havent heard

Soak in PB Blaster for 24 hours before trying again.

Instead of using a hammer on the wrench, I find it more elegant (and safer) to mount the wrench on the bolt with the wrench parallel to the floor and use a car jack to turn the wrench.

You are trying to remove the 13 mm bolts aren't you? Not the 19 mm bolts... You only need to remove the 13mm ones to do pads. Rotors on the other hand require the removal of the 19mm bolts. They are loctited in there. I usually use a breaker bar to get those broken loose and then use air to take them out. Hammering on a ratchet is only likely to get you a broken ratchet.
