I disassembled and cleaned my brakes with a brake cleaner because one piston wasn‘t retracting and the brake was dragging. I just need to know what kind of grease or lub to use on the pistons. Hyosung GT250R.
Brake fluid or as mentioned by others, a small amount of silicon during the re-assembly process. For your information, brake fluid is a lubricant. Be certain you are using the correct brake fluid. Major difference between DOT 4 and DOT 5. Good Luck
Do not use anything other than brake fluid. Make sure the piston and bore are clean. Ever wonder what makes the piston retract? As it moves forward during braking it slides through the O ring seal causing it to twist . Upon release of the brake lever/pedal the O ring un twists and forces the piston back into the cylinder. This requires friction between the O ring and the piston. You can see why lubricants would be a bad idea. Good luck.
Use brake fluidONLY brake fluid.
