Buyers Guide: Best Brake Fluids

Purpose

Every brake fluid available in the market has its varied purpose and formula for different vehicle types. There are different fluids for regular drive cars, whereas you can use some racing and regular vehicles. You must understand the brake fluid’s purpose. Then it will be easier to match specific needs, types, and brands.

Composition

Various components make up the brake fluid. These components are made to make sure that the fluid withstands pressure and high temperature. Therefore before buying any brake fluid, one must understand the composition.

Following are the standard brake fluid components:-

  • Polyglycerol: This solvent makes up the majority of the fluid (about 60-90%). Polyglycerol has less stickiness that contains ethers enhancing the dissolvability. It works well in all kinds of temperature conditions.
  • Lubricants: lubricants reduce friction resistance and improve fluidity. It is almost 5-30% of the fluid.
  • Additives: Additives are antioxidants and corrosion inhibitors. It reduces the oxidative decay of the polyglycerols. They are also helpful in preventing and reducing the rate of acidic deterioration. They consist of only 2-3% of the total volume of the brake fluid.

BEST BRAKE FLUIDS

Dry/Wet Boiling point

The dry and wet boiling points are always indicated in a brake fluid’s description to determine the vehicle’s performance. The wet boiling point measures the brake fluid once it is saturated with moisture. The dry boiling point measures the fluid boiling point when taken out fresh out of the bottle.

For those who change the fluid more often, the dry boiling point is more important. The wet boiling point is more important for those who do not change the brake fluid. While one owns the racing car, the high boiling point is taken into consideration.

Water Absorption

The tubes of the brakes are generally made of rubber. It allows water to infiltrate the system allowing corrosion and rusting. Ensure that the fluid has better water absorption so that your brake system can stay clear from corrosion for a longer time.

Frequently asked questions: Best Brake Fluids.

How does brake fluid work?

Brake fluids are incompressible liquid allowing the brake pedal force to the front and rear brake system. It helps the vehicle stop when the brakes are pressed. Also, it lubricates different brake components to make them work properly.

Why does brake fluid need to be changed?

Brake fluid is a fluid that absorbs water over time. Also, it might get dirty over time due to impurities, which further reduces its effectiveness. You must change the brake fluid to keep the brakes functioning.

 

BEST BRAKE FLUIDS

How often does one need to change the brake fluid of one’s vehicle?

This is generally determined by one’s driving habit and how often one uses their vehicle. But usually, you must change it within a gap of 18 months to 24 months. Some high-performance oil might even last three years.

How does one check their brake fluid?

To check your brake fluid level, you must locate the master cylinder which holds the brake fluid reservoir. But different signs of low or too dirty fluids are signs such as ABS light coming out and brake pedal issues.
