How To Replace The Rear Brake Lines On A 1973 - 1978 GMC RV

Part 2 of my series on the GMC RV brakes! If your rear brake lines look old they probably are! Don’t risk loosing a brake line and putting your stopping power at risk! The rear brake lines are a specialty part on the GMC and often go neglected. New ones can be sourced from all major GMC parts stores - I am using stainless brake lines from Jim Bounds at the GMC Co-Op in Orlando Florida. Make sure to use plenty of penetrating lubricant and line-wrench style wrenches, these parts see alot of road grime and easily can seize up. If your brake lines don’t want to budge, try using a torch and slowly working them back and forth. Support what I am doing! When you purchase products through the links I post, a small kickback is sent my way. Here is a good and cheap line wrench set that will cover all the sizes needed on the GMC: USA Made Line Wrench Set (SAE): https://amzn.to/34c8Oy2
