Brake Cleaning Preparation
The cleaner can be used on brake linings, brake shoes, drums, rotors, caliper units, pads and other areas of the braking mechanism while they're still intact.
Standard automotive brake fluid (DOT 3,4 and 5.1) are made from polyethylene glycol (PEG). PEG is soluble in water, methanol, ethanol, acetonitrile, benzene, and dichloromethane, and is insoluble in diethyl ether and hexane. A long way of saying it will clean up with soap and water.
When it comes to cleaning bike disc rotors, the general consensus is to use a specialist product that doesn't leave any residue, such as isopropyl alcohol. Hope says: "We recommend either methylated spirits or isopropyl alcohol as these both leave no residue on the rotors.
High-speed braking causes the most wear on your brakes. Pumping your brakes at high speeds can also put wear on your rotors. Damaged rotors can have an uneven surface area that will cause you to need to press the brake pedal down harder. This may cause you to need brake pads replaced more often as well.
