I need the schematics for running the brake lines for a 2002 GMC Yukon. The person who was supposed to do it took months & so I pulled my vehicle from him. Someone help so my son can sort this out? I am a 62 yr. old widow who just needs a safe vehicle! The motor in this has been rebuilt, I have a guarantee on that. I just need brake lines run & then brakes bled. Any help is very appreciated!
