What makes a 1996 GMC Suburban engine shut down and brakes lock?

A 1996 GMC Suburban engine may shut down and experience brake lock-up due to issues such as a failing ignition system, fuel delivery problems, or electrical failures affecting the engine's performance. Additionally, a malfunctioning brake booster or a vacuum leak could cause the brakes to lock up, particularly if the engine stalls and loses power assist. It's essential to check for diagnostic trouble codes (DTCs) and inspect the fuel, ignition, and brake systems to pinpoint the exact cause. Regular maintenance and timely repairs can help prevent such issues.
