With floating brake calipers, first clean all sliding surfaces, channels and contact surfaces using a brush or brake file. Also clean off coarse contaminants on used brake linings, pins and cross springs. Next, clean the brake components with Rapid Cleaner (Part no. 3318). After the solvent has evaporated, spray the cleaned parts with the spray on all sliding surfaces, channels and contact surfaces. After the propellant has evaporated, repeat the process if necessary.
