2002 GMC Yukon Q&A
2002 GMC Yukon Question: what componenet would I need to get fixed if my emergency brake is not working?
If I'm correct your system uses a rotor/drum combination. You have regular pads for stopping but inside that rotor there are re-designed brake shoes only used for Parking brakes (aka E-brake). The only way to tell if they need replacement or adjustment is to remove the rotor and visually inspect them. Just incase they need to be replaced I would buy the set in advance. If all they need is adjustment you can return the Brake shoes. - Angelo2975
