Reverse Hydraulic Handbrake Kit

Reverse Hydraulic Handbrake Package Specification

When drifting, OE cable handbrakes quickly reach their limit, especially as speeds increase and if your vehicle has larger tyres. A hydraulic handbrake is the effective, long term solution !

This handbrake had an inverted design : if you install it the "classic" way, you will need to push the handle in order to brake, instead of pulling the handle (see photo). This particular design allows to reverse your installation, so that the master cylinder will end up being at the front of the handbrake, not behind as usual. This design is recommended in narrow interiors, where installing standard hydraulic handbrake can be difficult. It allows you, for example, to place the master cylinder under the dashboard.

This handbrake has a 38 cm lever, giving you the ergonomics required. Lightweight and strong, its high quality ball jointed design ensures a short stroke, while guaranteeing no mechanical play. To be used in vertical position only, it comes with a 0.625" high quality Wilwood master cylinder, providing power and reliability for your rear brake calipers. 

Which Master Cylinder to Choose ?

Our hydraulic handbrake kits are supplied 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! 

With the above hose kit, fitment will be direct on the vast majority of cars used for drifting (Nissan S13, S14, S15, Skyline, BMW E30, E36, AE86...). 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.
