MotipFreezer Spray - 500 ml (Pack of 5)

This is the first time I've used such a product. I had both rear brake bleed screws well rusted into the rear calipers with expensive consequences if they broke off. I didn't want to apply heat for obvious reasons. I blasted the first screw for 7 seconds, waited a few seconds and sprayed again. I gave one moderate strike with a hammer and then attempted the release. With firm pressure using a 1/4'' socket set ratchet and 9mm socket, it released without any real trouble. I repeated the same on the other bleed screw with the same result. I was impressed.

The media could not be loaded.
