they have an issue with the crimps on the lines that leak over time, replace the lines, go to a hydraulic shop and have them build you the lines that way you dont have to worry about it anymore

08 LMM is alive and well again with a few add ons

This is what you want to do. Chase is right. The replacement lines from GM will start leaking again in time. go to a hydraulic shop and get new lines made and you'll never have to worry about it again. Plus it's cheaper. Should be easily under $100 for a new line. Lots of places are under $50, just depends on the shop. But do NOT waste the $100+ for the GM replacement line.
