Technical In order to remove residue (dirt and potential oils/grease from used rotors, and packing/shipping rust inhibitors on new rotors), the disc surfaces should be washed and scrubbed thoroughly with a fast-drying solvent, and if time permits, this should be followed up with a hot scrubbing bath with a detergent (Dawn dish washing detergent is a favorite). A hot soapy bath fol- lowed by a thorough hot rinse will aid in removing any contaminants that the solvent didn't remove. Also, if you do treat the rotors to a hot bath and hot rinse, it's a good idea to immediately follow this with a cold water rinse (this will reduce the chance of light surface rusting on the bare metal), followed by blow-drying with compressed air. EPB service Servicing a vehicle equipped with EPB (electronic parking brake) presents its own challenges. In order to retract caliper pistons prior to caliper removal, specific steps are required to avoid problems during both caliper removal and installation. Using a scan tool is typically going to be the manu- facturer's recommended method to retract the calipers to their service position to allow rear brake service or pad replacement. e scan tool is then used again to exit the service mode and automatically adjust the pads to the correct clearance after the rear brake service is performed. Refer to the February 2018 issue of Auto Service Professional (find it on www.autoser- for a technical article by Jeff Taylor that provides detailed look at EPB systems. Brake light switch While it won't affect braking performance, a faulty brake light switch will result in the loss of brake light activation. If a no-brake-light concern is found, naturally you'll inspect bulbs and fuses. However, if the brake light switch requires replacement, be aware that in some models (Chryslers, for example) feature a one-time-use switch. is type of switch is designed to set its adjustment during initial installation. If installation steps are not followed properly, or if a previously functioning switch is removed, it must be discarded and replaced. When dealing with this type of switch, don't be in a rush. Take your time to perform the proper instal- lation steps. Otherwise you'll waste time and money by buying and installing additional switches. ese switches are generally labeled with a warning ("Do not re-use", etc.). ■ Whenever dealing with brake system connections, never use an open-end- ed wrench. Always use a dedicated line wrench to avoid damaging/de- forming connection fitting hexes.
