PostSubject: Electrolysis for rusty brake disks?   Tue Feb 12, 2013 1:32 am

I havn't tried this, since I don't have to worry about the anal excesses of the UK MOT at the moment, but I ALWAYS failed on rusty brake disks, though the brakes were always fully functional. Never had any justification for this other than "because we say so", giving me the impression that it was purely cosmetic, which really PISSED ME OFF.

Replacing the disks was the only fix, and if I left the new disks on until the next test, they'd always be failed again.

I recently came across reference to electrolysis, using a battery charger with the object to be cleaned as the negative electrode, and it seems to clean to bright metal. If I ever have to go through a UK MOT again I'll try it, but maybe someone else might try it sooner? Just a thought.
