Drivers Side Floor Assembly Shown In The Pedal Up Position
Dual Brake Installation:
The TWIN STOP dual brake can provide an instructors brake on the passenger side that looks feels and works like the drivers side pedal. Purchasing the kit is a good start, but it does not provide the final product: Installation is a major part of the end result.
The positioning of the driving instructors side assembly is not that critical in terms of the functioning of the dual brake: A better looking installation and a more user friendly pedal can be obtained if the installer takes the extra time to get the unit as high up on the firewall as possible.
The critical part of the dual brake installation, in terms of the unit functioning reliably, is in the positioning of the drivers side floor mount assembly. This assembly must be mounted so the brake pedals clamp just comes along side the floor pulley upon complete brake deflection: See diagram below. On some applications this is easier said then done. An installer made installation bracket may have to be cut, bent, and drilled so that the floor assembly can be mounted to this and self-tapping screws fastened into the firewall at safe locations. One or two pieces of easily bendable, 1/8 or 3/16 inch thick, aluminum is included in each kit for this purpose. Please view the following illustration depicting a situation where the drivers side floor assembly could not be mounted directly to the fire wall because of numerous brake lines on the other side, and how a bracket was made to circumvent this problem.

We have found that the best results are obtained by individuals who have undertaken the installation them selves or have become closely involved into seeing that the unit gets installed right. The installation chore is more a job for the tradesman type of person as opposed to the auto mechanic: auto technicians while great at diagnosing problems and subsequently changing malfunctioning parts are often not the best at building something new which is really what the dual brake installation consist of. Someone with basic tools can perform the installation: The only auto mechanic knowledge really needed is knowing that drilling into a hydraulic brake line is not a good thing.
Will It Fit In Your Car?
Probably: We have not found a car yet that the unit could not be fit into. There are many different vehicles available to North American Consumers and they are all built differently in the area where the driver's side instructor brake parts are going to be fitted. Some vehicles are easy and simply involve screwing the dual brake parts into place: Many other vehicles have components in the way and thus custom made brackets need to be made to circumvent these problems. The question of "will it fit?" often times depends on how much time and effort the installer will want to spend.
Before ordering you may want to check your particular application to see if there is enough room on the floor beside the brake pedal for the floor assembly: You can find the dimensions of the driver's side parts using the following link: DIMENSIONS OF DRIVER'S SIDE PARTS
Also check to see if a 3/16 diameter flexible cable housing (much like that on your typical bicycle) will pass over to the other side with out any major bends.
As mentioned before; We have never come across a car that the dual brake could not be mounted in.
