My Fargo has Shimano centerlock rotors and had avid bb7 brakes on it. The rotors are not ice tech. I think I paid around 15-20 bucks a rotor. Today I installed new Jones bars and took my used but good slx hydros and installed them. I had to bleed them both out which made a mess. I washed my bike afterwards to clean up all the mineral oil. Some definitely got on the brakes. After washing I removed the pads and sanded them till they showed gold flakes again. I took rubbing alcohol on a rag and cleaned both rotors. This thing squawks so bad when I brake it is embarrassing. Not typical squeal or squeak but LOUD. What else can I do to bring them back to life. The rotors have maybe 300 miles on them. The brake pads on the hydros maybe have 500-1000 but still got plenty of lining left.
