Best Brake Fluid

 

What is a brake fluid? A brake fluid is one type of hydraulic fluid used to apply in motorcycles, automobiles, light trucks and even bicycles. You may apply it on hydraulic brakes or in hydraulic clutches. This is widely used when you want to transfer force into pressure and when you want to amplify braking force. By the word itself, brake fluids are of course, liquid. You may ask, is liquid applicable in transferring force into pressure as well as amplifying braking force? The answer is yes. Because liquid is not compressible. In the natural state of liquid, the component molecules do not have internal voids and the molecules pack together well. That’s why bulk forces are transferred directly to compress the fluid’s chemical bonds.

There are many types of brake fluids you can see on markets today. There are glycol-ether based brake fluids. There are also mineral oil based brake fluids.

Make sure that the brake fluids you will buy are approved by the SAE, or local government equivalents. Brake fluids must be able to meet the certain requirements as defined by the various standards they set. Just take note that all fluids must be colorless or amber so that it would be acceptable to be used on streets in the US. Well, except for the DOT 5 silicone which must be purple in color.

It is very true that most of the time, the brake fluids are the ones which are neglected most by the drivers. Mostly drivers would check the tire performance or tire pressure. Changing their engine oil in frequent intervals would also be on top of their list. Probably, no one would ever dare change the brake fluid in their street cars.

Brake fluid is used to provide an incompressible medium in order to transmit the pressure of the driver’s foot on the brake pedal. This is through the master cylinders to the calipers so that it would clamp the friction material against the discs. The foot pressure is then multiplied by the mechanical pedal ratio and also the hydraulic ratio of the master cylinders, booster and also the caliper piston.

This is just a very simple concept. When your brakes are fresh, your driving would be smooth and convenient. However, there are some problems you may encounter in the proper functioning of brake fluids. When the brake fluid is overheated, it will definitely boil in the caliper. It will then produce gas bubbles. And then it will eventually lead to a soft brake pedal. It would then be very hard for you to pump your pedal once it happens.

We will then discuss the boiling points. There are two classifications of brake fluids. One is the dry boiling point. And the other one is the wet boiling point. They are also classified by the US Department of Transportation or what we know as DOT. They are classified as DOT 3, DOT 4, Dot 5, and DOT 5.1.

The FMVSS 116 is what we call to the US Government specifications for brake fluids. The FMVSS 116 does not dictate the chemical composition of the said classification of brake fluids. It just defines the properties of the fluid. It defines the equilibrium reflux boiling points. The wet boiling point and the dry boiling point. The FMVSS 116 also defines the viscosity of the brake fluid. Viscosity is the property of fluids that causes them not to flow easily because of the friction of their molecules. It also defines the high temperature stability, the corrosion characteristics, as well as the effects of the fluid on seals, and also other physical properties like stratification, the tendency to form sludge or crystalline deposits. Stratification is the ability or the tendency to jell or separate.

The brake fluid has to be compatible with hoses and rubber seals to allow the braking systems achieve long service and optimal performance.

Most consumers tend to give high importance to the boiling point and the viscosity of the said fluid. Another thing that also deserves attention is the container of the fluid. Silicone based brake fluid naturally absorbs water from the humidity in the air. The container and brake reservoir functions as a barrier to the moisture in the air reaching the brake fluid. If you buy a brake fluid, make sure that the container is thick enough to provide a long life to the fluid once used.
