This video will show you how I replaced the rear brakes pads on a Lexus RX350 with the electronic parking brake feature. At first I was a little confused. Using my caliper piston compression tool, the caliper piston just wouldn't budge! After doing a little research, learned that there's a screw or piston inside the electronic parking brake motor that applies pressure to the caliper piston when energized and relieves the pressure when there's no current; that when deactivated, the parking brake screw does not retract away from the caliper piston. To get the screw to retract, 12v dc opposite polarity current must be applied to the electrical contact point. This is the workaround not having a bi-directional scan tool with software that can command the parking brake motor screw to retract for brake pad replacement service. After full retraction, the caliper piston can be compressed back into the caliper.
