The crucial final part of completing an installation is to be completely sure that the vehicle’s brake pedal / pedals are retracting back to their original positions. Installing any dual control onto a vehicle’s pedal is going to apply some force to it. This force will likely need to be counteracted in order for the pedal to go back to its original position. This can be done by installing a “Vehicle’s Pedal Supplement Spring” (VPSS)
Item #: txiss, Vehicle’s Pedal Supplement Spring (VPSS), Strap and Screw
This is used to supplement the vehicle’s pedal spring back. One end of the spring is attached under the vehicle’s dash and the other end is attached to the vehicle’s pedal using the strap and screw
The size and stretch of the VPSS is going to be determined by the dual control’s exertion on the pedal. This exertion is going to be very dependent on how the kit was installed and/or how adaptable the vehicle’s configuration is to the dual control. The straighter the “cable housing path”, the less the need for the VPSS and the better functioning of the dual control.
Pre-Installation, Pre-Purchase, Vehicle Inspection
The “cable housing path” is the main thing to look at when determining how a cable instructor brake kit will work in your vehicle. Cable operated Dual Controls were designed to be a universal type of system but too many bends in the cable housing will lead to a poorly operating system. On some vehicles, you’ll be able to see right through from the passenger side to the drivers, but more typically things will look solid with no way through. Take a close look. Pull off some panels if you must. You’ll just need a small opening to snake the cable housing/housings through and hopefully you can find a fairly straight route.
