INDIAN SCENARIO OF BRAKE-FLUIDS
                                             
Since the big giant of the world Automobile manufacturers are attracted in India and Indian roads are flooded with a new foreign Cars. These new cars have created the demands of new white Brake-fluid that is DOT-4 even the big Indian Lubricants Companies, which were Marketing DOT-3 (which is a sub standard, not up to the mark and not produced as per the International standards). Started worrying about the DOT-4. Very few of them tried to Manufacture but could not come, up to the mark with the product. The vacuum for DOT-4 in India is widening day by day and 90% of the demands for DOT-4 is imported.

Brake Fluid is a critical security factor that controls safety of the vehicles, and synthetic Hydraulic fluid represents an important factor in the braking system.

Constant Research and Development in the Automobiles, particularly in the braking system by the Advanced Countries shows that the oil bound brake fluid have been replaced with the synthetic One, for the processing of the synthetic material. They have designed new plant to suit the processing of the synthetic material with a latest technology in sophisticated designed plant with nitrogen application blanketing system.

In India Brake Fluid Manufacturers have opted Synthetic material to some extent but they could not come up with the new designed plant accordingly, either they are lacking know how. That is why even the DOT-3 Manufactured by the Indian Companies are lacking purity and perfection. As a result the statistics report shows that the accident happening on the rods, 75% of those are because of brake failure this is the well-known facts.

If we came up for the first time in the entire subcontinent with such a latest technology with complete know-how which will have very strong impact on the economy, improve and hike the safety standard in the region. The Indian and Foreign lubricant companies and vehicle manufacturers will recommend the only brake fluid available with purity and perfection for the safety of their customers.

INTRODUCTION

Brake-fluid is critical security factor that controls safety of the vehicles and synthetic Hydraulic fluid represents an important factor in the braking system of motor vehicles. So the Brake-Fluid must be regarded as an important functional element.

The different grades and their destinations are based on the international specifications. Thus the Brake-Fluid range mainly consist of DOT.3 DOT.4 DOT.5 these range Contain products that fulfill the minimum requirement of the particular grade and product Satisfy additional requirement of particular motor vehicles manufacturer.

HISTORY
Automobiles were first equipped with hydraulic Braking Systems in 1924. Alcohols particularly polyhydric alcohols such as glycerol and glycerol water mixture were used as Hydraulic fluid. These products fall far short of the requirement of today's technology and are only of historical interest.

ADVANCE TECHNOLOGY
We are introducing for the first time in Sub-Continent the Brake-Fluid Produced under Nitrogen Blanketing Application system (NBAS) which is a Advance Technology with Complete Know-How and which will have very strong impact on the economy, improve and hike the safety standard in the region. The products such as DOT.3, DOT.4 and DOT.5 will be an important substitute, besides it can be exported to the international Market mainly the third world countries, as the product is competitively better in quality and lesser in price compare to the standard of most advanced and developed countries.

QUALITY ASSURANCE
Quality assurance is an important component of our policy. Its purpose is to achieve a consistently high quality standard of our product and services to meet the requirement of local and International market.

The success and best results achieved by us are reflected in the results given by the leading institutions, and after testing and practically using by a World's leading high quality industrial and Automobile component manufacturer from Germany.

MODE OF ACTION OF HYDRAULIC BRAKE-FLUID
The Brakes are actuated by pressing the Brake Pedal, usually with the assistance of Vacuum in the inlet tract of the motor, for example, this produces pressure up to 100 bar in the Braking System, The pressure developed in the Master Cylinder is transmitted equally in all direction in the Brake pipes. According to Pascal's Law, the Pistons in the Wheel Cylinders of the drum and or disc brakes are moved by the pressure in the fluid. These in turn press the brake pads or shoes against the disc or drums. Many Vehicles are fitted with drum brakes on the rear wheel and disc brakes on the front wheels. Heavy, Powerful automobiles are fitted with disc floating calipers. The latter occupy less space and are mainly used in vehicles with negative-scrub steering geometry. Dual Circuit braking systems have found increasing use in the construction of modern vehicles. To meet the higher safety requirement, in these systems, the master cylinder is divided into two independent pressure chambers. This tandem cylinder makes it possible to actuate two independent hydraulic systems and to avoid the failure of the entire braking System in the event leakage-e.g. From the pipes or one of slave cylinders. With dual-circuit brakes, either the cylinders of diagonally opposed pairs of wheels of those of the front pair and rear pair are actuated by the separate hydraulic systems. When a vehicle Brakes its centre of mass is shifted in the direction of travel. It is therefore worth providing the front wheels with powerful brakes as according to Pascal's Law, the pressure in the brake-fluid in all slave cylinders is the same, the design of the braking system must provide for an optimum of distribution of braking force.

HEAT RELEASED IN THE BRAKING PROCESS
Braking is the conversion of Kinetic Energy into heat by friction. The quantities of the Heat that results are considerable and depend on the weight and speed of the vehicle. A motor vehicle with a weight and speed of the vehicle. When a motor vehicle with a weight of one ton is braked to a stop from 100 MPH approximately 965 KJ(=230 KCAL) of thermal energy is released. This quantity of heat is enough to melt 1 KG of Cast Iron with a mean rate of deceleration of 7 m/s, the Braking process lasts about 6.5 S. The above quantity of heat representing about 150 KW(=200 BHP) is released to the environment. Most of the heat is dissipated to the surrounding air. Designers are constantly working on even better system in America and European Countries. Be they in the form of ventilated disc brakes of specially designed body work with ducts for cooling air nevertheless, under extreme conditions, the brake-fluid is exposed to considerable heat and may reach temperature of 150 and more.

VAPORS LOCK-BRAKE FAILURE THROUGH VAPOR FORMATION
High temperature lead to premature aging of Hydraulic Brake-Fluid, because of mineral oil or any other country oil is mixed with the fluid as Anticorrosion, and are also very bad for the rubber seals, particularly those in the wheel cylinder on disc and drum brakes.

However the possible formation of pockets of vapour and gas in the Brake-Fluid at excessively high temperature is much more serious. When they are exposed to great heat, the component of the Brake-Fluid break down into Gaseous products that form vapour pockets. Steam forms in Brake-Fluid with higher proportion of water when they exceed the boiling point. In contrast to Liquids, Gases and Vapours are compressible. When the brake paddle is pressed down, the master cylinder is only 5-15 ml, in such cases, the brake paddle can be pressed fully home with out developing the necessary pressure for braking and the brake fails to operate, this is described as "Vapour Lock" in the trade. Brake-Fluid must therefore be formulated to ensure that, under operational condition, the Brakes can be Relied upon not to fail from these causes.

REQUIREMENTS FOR BRAKE-FLUID
The Brakes are safety component in the motor vehicle, the Brake-Fluid must be regarded as a functional element, the requirement, as expressed in the test specifications of the standard, must take this into account.

HYGROSCOPICITY
It is never possible to completely prevent water finding its way into the Braking systems. Critical component include the wheel cylinder, theBrake-Fluid reservoir and the high-pressure hoses, which are permeable and allow slow diffusion of water through the layers of fabric and rubber. Brake-Fluid has the favourable ability to bind water that has penetrated the system, so that it does not freeze at low temperature and block the system. This property known as Hygroscopicity.

EXCELLENT LOW TEMPERATURE STABILITY
No solids must separate out at low temperature and block the system, which would lead to Brake Failure.

GOOD TEMPERATURE/VISCOSITY PERFORMANCE
The Braking process lasts a few seconds, i.e. the force applied by the driver to the paddle must be transmitted rapidly to the drum or disc brakes. The test on each batch therefore includes viscosity test over a very wide range of temperature.

EXCELLENT CORROSION PROTECTION
Braking systems contain dissimilar metals in contact, because of their different position In the Electrochemical series, there is a tendency for the less noble metal to pass into Solution-it corrodes. The Brake-Fluid therefore contain effective corrosion inhibitors for Steel, Cast Iron, Tin plate, Aluminum, Brass, Zinc, Copper and Cadmium. The anticorrosion action of each batch is therefore checked before release. In this test, to which water has been added, at 100 C for 120 hours. The change in weight of the metals specimen is then determined, their surfaces inspected for changes, and Brake-Fluid checked for sediment.

COMPATIBILITY WITH RUBBER
A piston seal used to seal the gap between the piston and cylinder against the loss of Brake-Fluid from the Brake cylinder, further, fabric reinforced rubber hoses are often used to link the components of the Braking system. The piston seal only functions Properly if it is swollen slightly by the Brake-Fluid. This gives better contact between the lip of the seal and the metal surface. If the swelling exceeds certain limits, the 'O' Rings in particular are at risk. Brake-Fluid must, of course, not cause the piston seal to Shrink. Swelling test are carried out at 70 C and 120 C on standardized SBR and EPDM rubber. Specimens, in which changes in the volume, diameter and hardness of the specimen is measured.

LUBRICATING ACTION
Both the master and wheel cylinder of drum and disc brake systems contain pistons that must be able to move freely. To reduce friction and wear, special additives are added to Brake-Fluid as Lubricants. The Lubricity is constantly in simulated severe service test.

STORAGE AND DETERIORATION
Brake-fluids only have a limited shelf life. However produced under the Nitrogen Blanket, in the tightly sealed original containers, this Brake Fluid can be stored for five years. In practical, it is recommended to change the Brake-Fluid at least every two years to ensure reliable operation even under extreme conditions. In any evnt.
