Blockages in the check valve allow air to penetrate the brake fluid and form air bubbles, lowering hydraulic pressure in the master cylinder, resulting in less efficient braking. Furthermore, frequent breakdowns are found due to damaged internal parts or a blocked check valve, which is possibly due to broken grommets, causing vacuum leak from the booster and ultimately resulting in less brake power amplification. To solve this issue, we have designed a large-sized diaphragm with appropriate material, which is vulnerable to leaks. However, the larger the diaphragm, the greater the amount of power assist. This problem is much more prevalent in cold, dry climates, where the diaphragm material degrades more quickly. Vacuum leaks cause the engine to idle poorly and pause while accelerating.Īnother issue is, a large internal diaphragm in the vacuum brake booster gets harden and develops internal leaks over time.

A loose or cracked hose, which lets air into the system, is typically the problem. The main source of concern is low vacuum pressure from the engine. In the present system, concerns have been raised about vacuum brake boosters of LCVs, which are responsible for the increased stopping distances and, as a result, the risk of accidents. In this paper, we present an optimized system that addresses these current issues by proposing major design changes and material improvements, taking into account all of the parameters that can influence the efficiency of the commercial vehicle braking system. Partial intake vacuum, the smaller size of the diaphragm, leakage in the master cylinder, or the injection of brake fluid into the booster is just a few of the factors that can reduce the effectiveness of the brakeīooster. The failure of a diaphragm or a check valve may result in a loss of power assist. However, when it comes to the brake booster of a light commercial vehicle, there are a few problems that must be discussed. This lowers the amount of pedal effort needed to bring the vehicle to a stop, making braking easier and safer. It multiplies the applied force by nearly two to three times.

When the brake pedal is pushed, a vacuum is circulated through it, which applies pressure to the hydraulic brake lines. The brake booster is powered by a vacuum system connected to the engine's intake manifold.

Without it, stopping distances would be much longer, placing the driver at the risk of a collision while performing an emergency stop.

This unit assists in stopping the vehicle by providing additional force to the brakes. The brake booster also plays a crucial role when stopping a car with disc brakes. In this system, a vacuum diaphragm is linked to the vacuum port of the engine intake manifold. Many vehicles today use vacuum-assisted brake systems because of their simple design and use of intake vacuum to multiply brake force.

During this, we calculated and tested the system while keeping the critical values of parameters for LCV in mind.

This is carried out by comprehending and troubleshooting various current problems associated with the system, designing and modeling the brake system's components using SolidWorks, which include the brake booster, master cylinder, and brake pedal, analyzing a variety of suitable materials by utilizing ANSYS Workbench software and testing the optimized model. Following this, the work presented in this paper focuses on the design and development of a Vacuum-assisted Power Brake System for Light Commercial Vehicles (LCVs).

Improvements in the braking systems will only be possible through basic research, the application of sound engineering concepts, and testing, resulting in small but significant design changes. Vacuum brake boosters are now widely used in a variety of vehicle types, ranging from small cars to heavy commercial vehicles.
