GMC Sonoma engine dies when braking despite replacing brake booster and switch on GMC Sonoma

Some GMC Sonoma owners report experiencing issues with the engine dying when braking, even after replacing the brake booster and switch. These problems may stem from a faulty sensor related to the braking system, such as the brake light switch, which can disrupt engine performance. Additionally, some owners have encountered vacuum leaks that persist despite the brake booster replacement, affecting engine operation during braking. Another concern is brake fluid leakage into the vacuum hose from a malfunctioning master cylinder, which can lead to stalling when brakes are applied. Furthermore, some vehicles have an engine shut-off feature that may malfunction, causing the engine to die unexpectedly when the brakes are pressed. Lastly, issues with air intake can arise, as applying the brakes harder may draw more air into the engine, leading to sputtering and stalling. It is advisable for owners to conduct further diagnostics to identify the root cause of these issues.
