They are squealing and seem to want to hold when going up inclines. How can i properly adjust these to work correctly? What needs replacing just the shoes or does someone make a kit to rebuild it? Also the highlifter kit for the rear is just one disc on the right rear or does it go to both wheels? I have heard that HL's pads wear very quickly, is this true? And how long do rotors tend to last? sorry for all the questions but thanks for the help
