Choose a radial master cylinder

On most motorcycles and quads, the installed master cylinder is axial. On more sporty canters, or on sporty quads, it can be radial. The difference? The way the lever will push the piston. The sketch below will show you the difference between radial and axial.

Derived from conventional braking, radial braking is made up of two elements: the master cylinder (roughly, the lever) and the caliper (roughly, the "gripper") on the disc). What changes is the position of the stirrup on the fork, and the way of exerting the force of the lever on the front brake system. Radial braking is smoother, more precise and more powerful.

The advantages of the radial master cylinder

Advantages are :

- Better braking efficiency

- Better precision in the response of the system to the master cylinder, almost completely eliminating the empty stroke of the lever due to â € ?? elasticity â € ?? of the caliper.

- Longer platelet life. With radial fixation, the pads work with better alignment par compared to the disc, since the caliper is kept rigorously aligned in a theoretical working position even during extreme stresses.

This extends the life of the pads, primarily because this perfect alignment allows their surface to wear evenly.

 · Better stability of the braking system with less difference between cold and hot

 · Better stability of the front axle, due to the widening of the center distance of the brake discs (+ 2,5 mm par side) to adapt them to the new brake calipers.

The major drawback remains the purchase price.

How to choose your master cylinder?

The master cylinders are available in several materials and formats, they adapt to all motorcycles and quads.

1- Manufacturing process: forged or cut in the mass (CNC)

The forged is the business model. From a mold, we "sand" (pour) molten aluminum, in order to obtain a raw part. Next, the cylinder, where the piston is housed, as well as the fixing of the lever and the bride of the master cylinder, will be machined on a numerically controlled machine. The cut in the mass is entirely machined on numerical order, from a block of aluminum. This technique brings several advantages. First, the aluminum block has better mechanical properties, i.e.ar it has undergone several treatments (rolling, soaking, etc.). In addition, this manufacturing technique allows for the construction of lighter master cylinders, such asar completely drawn and optimized on computer.

2- Master Cylinder Format : How to choose the piston diameter of your brake master cylinder (first value): The PR 16 is recommended for motorcycles equipped with:

- of a single brake caliper 4 pistons

- two floating calipers with 2 pistons each (4 pistons in total)

The PR 19 is recommended for motorcycles equipped with:

- two calipers 4 pistons

- two calipers 6 pistons

How to choose the center distance of your brake master cylinder (second value):

16, 18 or 20 ???

These figures correspond to the distance between the pivot of the brake lever and the fulcrum on the piston. The shorter the distance, the more powerful the brake grip and vice versa.
