CNC71 Hydraulic Handbrake Kit (Removable Handle)

CNC71 Hydraulic Handbrake Kit (Removable Handle) Specification

Specialising in CNC turning and milling, Polish company CNC71 is offering this hydraulic handbrake, ideal for drift use. This kit ensures that the rear wheels lock quickly and firmly, as well as providing a constant braking force that is much easier to control than with the standard handbrake.

Particularly discreet, this kit allows all the parts required for fitting to be concealed beneath the centre console components. The hydraulic handbrake lever is simply screwed in, so it can be removed and put back in place in a few seconds. The structure is made of high-strength metal to ensure excellent rigidity. Finally, the installation is 100% reversible and does not permanently alter the original parts.

Which Master Cylinder to Choose ?

Our hydraulic handbrake kits are compatible with standard master cylinders, suitable for common use on most vehicles (road, trackday). For heavu duty use, in competition, with a very torquey engine and very wide or semi-slick tires, we recommend opting for a higher range from Wilwood or AP Racing (optional above).

The ideal diameter of a master cylinder is often the subject of much debate, while the answer is very simple: there is no ideal diameter! Every driver and every vehicle is different. Without going into great theoretical explanations, remember that the larger the diameter of the master cylinder, the more liquid it moves when you pull it: the stroke of the lever will therefore be shorter and firmer, the effort to be provided by your arm will be higher. It can be difficult to properly dose braking in these conditions. On the contrary, with a small diameter master cylinder, the stroke will be longer, the lever easier to pull, and more dosable.

Generally speaking, a diameter between 15.8 mm and 19.1 mm is a good compromise for all uses. Otherwise, do not hesitate to contact our technical staff for more precise information, especially if you are using large multi-piston calipers. Several master cylinders are available in our braking section, offering many variations in diameter, with or without brake fluid reservoir for separate calipers dedicated to the handbrake.

For quick, easy and safe mounting, select the optional hose kit above! 

The hoses provided simply replace your stock rear brake line, and add the handbrake assembly into the middle. They connect at the front to the master cylinder/ABS unit and into the rear caliper T-piece at the rear of the car. See the picture below for a diagram.
