Short term brake fix

In my experience just cleaning the drums with a solvent is a very short-term fix (a week or so) The metal in brake drums is quite porous and the fluid actually gets absorbed into the surface and the next time it is subjected to heat during braking the fluid will leech back out again contaminating your nice new brake shoes. Most mechanics wipe clean first and then gently heat the drums with a blowlamp or hot air gun and then give them a light emery during this process you can actually see the fluid coming to the surface. If you dont believe me give it a try you will be surprised. There is a sure way of detecting a left-handed nut or bolt it will have small notches on each corner this is the international standard. I doubt if its a left handed nut on your car but have a look and see if there are any notches as I described.
