hello have had issues with my parking brake for some time; dealership would constantly adjust for me when in for regular maintence. Out of warranty now and need to do this myself. Problem I'm having is that the cable seems to be loosening (once parked on an incline and the parking brake set after car is in park the car will roll a little and at times makes a groaning) i have a toyota lubricant part number 00530-1pl00 which works for the groaning and rattle but fell I may need to brake out the tools. Any suggestions??
