Brake valves, also known as load-sensing valves, use the weight on the rear of a vehicle to calculate the amount of brake fluid pressure required to safely slow the rear wheels. Broken or faulty valves can result in potentially dangerous braking. Pushrods physically connect your brake pedal to the master hydraulic brake cylinder, relating the pressure from the driver to the amount of brake fluid that's pushed into the system. Unreliable pushrods can reduce the effectiveness and response time of your brake system. Brake valves and pushrods need to be kept in good condition and, while they are often changed when the brake system is serviced, they sometimes need to be replaced independently. The quality of both devices is essential to keeping your cargo safe, whether it’s your shopping or your passengers.
