BRAKE SHOE SET FOR RENAULT 21 F3N722/723/726 F2N750/752/712/711/754 1.7L 4cyl TRW GSK1047

Brake shoes are the most important element of the mechanical part of the brake. The efficiency of braking depends on them and this causes a number of serious requirements for their quality and characteristics.

The construction of the brake shoe

The proportions of the TRW brand Brake Shoe Set are clearly maintained. Any change in the proportion of one or another component can significantly change the properties of future brake shoes, up to their complete inoperability. The friction lining is the most important part of the brake shoe. Its main tasks are to obtain the necessary frictional forces during braking and to ensure the stability of the coefficient of friction when changing the speed of rotation of the brake disc and the pressure in the system. The natural desire of car manufacturers (as of developers and manufacturers of brake shoes) is to obtain a coefficient of friction close to a constant under any operating conditions. It is not easy to fulfill this requirement, as evidenced by the entire world experience. We can only talk about finding the optimal combination of the properties of the shoe.
