I MANAGE A FLEET OF 53 SCHOOL BUSES, MODEL YEARS RANGING FROM 2008 TO 2015. I HAVE NOTICED A TREND WITH THE HYDRO BOOSTERS AND MASTER CYLINDERS, THEY TEND TO LEAK INTERNALLY ON THESE GM VEHICLES SOME HAVE BEGUN TO LEAK AS EARLY AS 30,000 MILES. I EXPECT TO HAVE TO REPLACE ALL OF THESE COMPONENTS, ON EVERY BUS IN THE NEAR FUTURE. AS THE FLEET AGES THE TREND IS GETTING INCREASINGLY WORSE. I BELIEVE THIS IS A DANGEROUS SITUATION BECAUSE I AM VIGILANT WITH KEEPING UP ON THIS ISSUE, HOWEVER I AM NOT SURE THAT THE GENERAL PUBLIC WILL HAVE THE SAME UNDERSTANDING ABOUT THE DANGER OF THIS DESIGN FLAW. I HAVE HAD BUSES COME IN BLEEDING BRAKE FLUID OR HYDRAULIC FLUID.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list.
