Front Left brakes.....bolt to take the pads off...theres 2 allen bolts....i got one free..other one...would not come lose...so i ended up rounding it off it doesnt stick out so im not sure how to get it out.....trying to replace front brake pads lol...anyone help....my dad doesn't know what else to do...

 

Obvioulsy try the old wd-40 and let it soak trick.
After that , can you get into it with a dremel and small cut off wheel? I have cut a slot in stripped bolts and remove with a reg screwdriver. You can try to drill it out. You can get a easy out, but usually they just break too, if they break off they are pretty hard to drill. Last resort is to weld a bolt to it and back it off.
Good luck.

 

your best bet will be to drill it out and buy a new screw.

 

I put liquid wrench on it before i tried to get it out...i will try the grinding wheel thing with the dremel.
