At what speed will the car stall when braking in 5th gear?

When braking in 5th gear, the car will stall at approximately 25 mph. There are three types of braking systems: 1. Foot brake - The most commonly used brake while driving, operated by foot, hence the name. When the driver presses the brake pedal, the braking force is transmitted mechanically or hydraulically to the wheel's braking device to create friction. 2. Parking brake - Also known as the handbrake, it prevents the vehicle from sliding when parked. There are generally two types: the intermediate brake type installed on the driveshaft and the direct control rear wheel brake type. 3. Anti-lock braking system (ABS) - When driving on slippery or icy low-friction roads, excessive braking can cause the wheels to lock up and lose traction, leading to a loss of directional control. To enable effective directional control in such hazardous conditions, the ABS (Anti-lock Braking System) was developed.
As a driver with years of experience in manual transmission, I often cruise in fifth gear on the highway. When braking to slow down, I have to be careful because the car tends to stall when the speed drops to around 10 to 15 km/h, as the RPM falls below idle speed and the engine can't sustain it. I remember one night on the highway entering the ramp, I forgot to downshift, and the car stalled directly at 15 km/h. The steering wheel instantly became stiff, which was extremely dangerous. So now I’ve developed the habit of downshifting while braking—I watch the tachometer, and once the RPM drops below 700, I immediately press the clutch and shift to a lower gear to keep the engine running smoothly. Different cars behave quite differently; newer cars tend to have more stable idle speeds, while older ones might stall at 20 km/h. Developing good habits can extend the lifespan of mechanical components. With more practice, you’ll naturally get the rhythm—don’t wait until the speed is too low to react.
