A Brake proportioning valve mounts on the right side frame rail back by the rear axle. Aftermarket valves can be dangerous. Get it wrong and you may not be able to stop in time or improperly locked tires can cause you to veer out of control. Avoid serious damage or possibly even death. Why risk the constant adjusting of an aftermarket valve when you can install this brand new valve that is already balanced right for your Suzuki Samurai?
*Square dash models have a single rear brake line from the proportion valve to the axle housing. To use this product you would have to convert to two separate bleed-able wheel cylinders. We do not provide or sell those parts.
