Quality Brake Fluid plays an important role within your Volkswagen Polo braking system. 

The force exerted by the driver of the vehicle to the brake pedal, allows the Hydraulic Brake Fluid to flow through the Brake Lines to the Brake Calliper Piston which brings the vehicle to a stop.

A good Quality Brake Fluid must contain a number of crucial elements for example, A High Boiling Point which will prevent Brake Fade, Cooling properties which will cool the Brake System and also in Modern Braking Systems a Low Viscosity Brake Fluid is required. These Hydraulic Systems contain narrow Bores and Channels so selecting the correct Brake Fluid is Important.
