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.

Traveling at 50 to 55mph I make a easy brake application and the front wheels will start oscillating until the front goes into a violent shake. Releasing the brake will stop the shaking. This is a cutaway school bus. I'm the mechanic and the driver brought it to my attention. She noticed it while braking on a downhill. I was able to duplicate it on a level surface. Haven't found the fix yet.

This is a brand new bus, GM chassis. It has a limited slip differential. The brake lines are routed in front of the rear differential. Twice, we have had rocks hit the brake line and sheer it off causing total brake failure. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
