How do buses brake?
How do buses brake? They use a triple-valve principle which charges air into the tank, applying the brakes, and releasing them. Pressure increases in the cylinder while applying the brakes and in turn decreases pressure in the reservoir.
Why do busses sway?
Weak springs (leaf or coil) or a lack of anti-sway bars can contribute to excessive sway, and on air bag-equipped chassis, it can be the very act of the air entering/exiting the bags.
Why do we feel jerk when bus stops?
This is due to inertia. When the speeding bus stops suddenly, lower part of the body comes to rest while the upper part of the body tends to maintain uniform motion.
