Engine Idle Drops When Braking at Susanne Lumpkin blog

Engine Idle Drops When Braking. However, when the engine rpm drops below the normal range of 800 rpm (for most cars), it is more than likely that you are. If your brake pedal is stiff and it stalls when you apply the brakes, it sounds like the diaphram in you brake booster may be. If your engine is not running strongly at idle (multiple reasons for that) the additional electrical load will cause the idle to drop. However, when the engine rpm drops below the normal range of 800 rpm (for most cars), it is more than likely that you are. If your idle speed increases when the brakes are applied then the booster is allowing some of the manifold pressure (vacuum) to. The brake lights put a load on the alternator. Check for vacuum hoses that are torn, disconnected, or missing. The brakes are then pressed, the engine feels like it will stall, and the idle. You brake system relies on vacuum and an idle speed that is. This occurs when the diaphragm inside the brake booster fails and allows air to bypass the seal.
