So I am replacing both calipers on my 98 Warrior 350 because both of them were frozen and I’m not going to spend the same amount of money rebuilding them. The new ones were $40 shipped and come with a 3 year warranty. Some ECM pads later and I’m set. However my brake fluid was nasty and rusty colored. Is the only thing I can use to rinse them out before installing the new calipers denatured alcohol (which I don’t want to buy for $15) or can I use some ISO and just blast the compressor air through it? Also, Should I tear apart the master cylinder and clean every part or leave it alone?
