Sim Handbrake

This page contains instructions on installing and adjusting the Heusinkveld Engineering Sim Handbrake. This is a true pressure sensitive and solid handbrake for the ultimate rally or drift control in your favorite racing simulations.

Mounting the handle to the base

Your Sim Handbrake offers a lot of flexibility, with a handle that can be adjusted in 120 degrees in infinite steps. This paragraph contains instructions and images to mount the handle in the standard ‘flat’ position. The same mounting principle applies when installing the handle in any other angle to the base (also see next paragraph).

1) Mount one side bracket to the base of the handbrake. Use 2 treaded bushes, 2 bolts, 2 washers. Do the bolts just finger tight.

2) Mount the second bracket to the handle. Use 2 treaded bushes, 2 bolts, 2 washers. Do the bolts up just finger tight. Double check the orientation of the bracket.

3) Join the handle and the base part, insert the 4 remaining bolts with washers, finger tight.

4) Make sure the brackets are nice and symmetrical and tighten the bolts fairly tightly using the provided allen keys.

Adjusting the handbrake handle

Each installation may require a different optimal and ergonomic positioning and angle of the handbrake. Look at the schematic below to find the bracket and handle position to get the
mounting angle that is right for you. The angle of the handle can be adjusted in 120 degrees infinite steps.

Adjustable handbrake force

By swapping the rubber in the handbrake you can adjust the maximum force of the handbrake. With the white rubber the maximum force is about 10kg (22lbs) The green rubber makes this about 17kg (37lbs). These values are indicative.

In order to swap the rubbers, identify parts 1 to 4 below (also see the image) and follow instructions A to D.

Parts list:

1) Bolt head (13mm hex)
2) metal washer(s)
3) metal washer(s)
4) preload nut (13mm hex)

Rubber replacement instructions:

a) Loosen preload nut (4)
b) Loosen bolt (1) and pull out
c) white = soft, green = hard rubber
d) put back in order

Don’t over tighten 1. After preload, the rubber length must be 30mm or more (1.18 inch) You can pull until you feel you hit an end stop, but you can also calibrate to a lower force level.

Mounting the handbrake

Mount the HE Sim Handbrake to a solid cockpit or frame. Mounting slots for M6 bolts are dimensioned as seen in the image below. This is a top down view, the brake handle is oriented from left to right. All dimensions are in millimeters.

Connectivity options for the Sim Handbrake

The Sim Handbrake exists in two versions:

  • Supplied without USB-controller (sold around december 2014)
  • Including an external USB-controller (sold from september 2015 onwards).

Connecting the Sim Handbrake supplied without USB-controller (sold around december 2014)

If your handbrake was supplied without controller, you have the following options to connect the Sim Handbrake to your PC:

1) Acquire a standalone Load Cell Amplifier (such as this one by Leo Bodnar). Hook up the handbrake to the load cell amp, then hook up the load cell amp to any free analog axis on a USB game controller board (our Sim Pedals USB Controller features additional free analogue axis).

2) If you do not own any type of USB game controller board yet: A device such as the Leo Bodnar BU0836-LC board (it must feature a load cell amplifier) will allow you to connect the handbrake.

Connecting the Sim Handbrake supplied with external USB-controller (bare wire version – sold from september 2015 – april 2016)

If you have the handbrake which came with an external controller and 4 wires from the load cell, you need to connect the wires of the handbrake loadcell to the supplied controller using screw terminals.

Wiring of the handbrake

The wiring of the Sim Handbrake is as follows:

Red(5V+)
Black(GND )
Green(SIG+)
White(SIG -)

Load cell sensitivity is 2mV/V.

Connecting the Sim Handbrake supplied with external USB-controller (RJ-plug version – sold from May 2016 onwards)

If you have the handbrake which came with an external controller and an RJ-plug load cell, you need to take the following steps:

 

  1. Identify the different parts (RJ plug from the load cell, small interface board and main USB Controller Box.
  2. Insert the small interface board in the 4 screw terminals, with the socket pointing towards the corner. When the interface board touches the corner pillar of the USB controller box, it is inserted just right. Tighten the screws (all 4) using a small screwdriver so the interface board is secured to the USB Controller box.
  3. Insert the RJ plug from the load cell in the RJ socket on the small interface board.

Calibrating the handbrake

In order to calibrate the handbrake for Windows we recommend using DIView Calibration Software (ZIP). The handbrake acts just like a brake pedal, the video below shows a detailed instruction on how to calibrate a pedal within DIView. This calibration method will work for all software which uses the standard Windows calibration protocol.

Please not that many simulation software does not support an analogue handbrake yet. Please refer to the documentation of the simulator software to see what the possibilities of using an analogue handbrake are.
