The Role of Banjo Fittings in Braking Systems

A banjo fitting is a type of bolt found in several industries across the globe. It has perforation making it the best fluid transfer machine. The banjo fittings area of application include automotive, oil, hydraulic systems and many more. Its appearance determined its name “banjo”. It has a thin pipe connected to a big round body part. It looks like some common musical instruments.

Brake Systems

Banjo fittings are so widespread across the world that almost everywhere you go banjo fittings are available. Since they are used in braking systems, it is obvious you will find them in cars, buses, taxis, and many others. The braking systems in any automotive ensures that the machine is stopped from moving. For vehicles, it ensures that they stop on horizontal even if the driver is not available. The process involves a lot of manual action hence the name handbrake. Apart from service braking, it has a unique command. In most situations, the handbrake system acts as emergency brake. The auxiliary brake system acts as additional brake. It has similar task as the main brake. However, it is majorly employed when its effects influences the service brake. The braking systems are of different constructions. Their outlook determines their categories. For example, they are classified according the geometrical nature of the fixed and rotary pieces.

Examples of brakes as per rotary pieces include disk and drum brake. By the structure of the fixed parts, the brakes can be categorized as with band, with sabots and with platelets. You must be wondering where banjo fitting has gone to. In fact, it is in the braking system handling the liquid. Banjo fittings are mainly designed to transfer liquid more efficiently. It has high resistivity to pressure. In mini cars or normal cars, banjo fittings can withstand over 5o bars of pressure. Less experienced mechanics normally confuse the fittings as flareless fittings. The reason is that they both handle fluids. The difference is flareless fittings acts like a close for the compression at the terminal of the hose. In addition, the hose barb fitting acts as a seal just like the flareless.
Many vehicles with braking systems of multiple circuits are more reliable and safer. In some countries, the law requires vehicles owners to have braking system with a number of circuits.

Types of Banjo Fittings

Banjo fittings are available in different sizes. The braking system type determines the size of the fittings used. Now, it is majorly implemented in the latest car systems. Second hand vehicles do not contain banjo fittings. Banjo fittings are bought in sets and not as one piece. A banjo fitting of 5 pieces is about $30.

Most of banjo fittings are made of steel and coated with zinc, copper, or nickel. However, some manufacturers may choose a different material depending on the area of use of banjo fittings. In most cases, the draftsman selects the type of banjo fitting he would use as per the car designs. The main types of steel used in producing banjo fittings include OL 60, OL42, OT 60, OT45, OLC40, and OLC 25. These are the best quality of steel types. Depending on the other physical properties requirement, the manufacturer may opt for non-metallic or other metallic materials.

In particular, you may purchase banjo fittings fitted with banjo valves. However, this is rare in the automotive industry. It is important to note that there is a special kind of fitting known as banjo rubber fitting. Banjo rubber fittings have high resistance due to its elasticity. However, it cannot be used in braking systems due to its nature and instead is used in electrical industries.
