I am contemplating the fitting of a hydraulic handbrake to my newly converted Estelle. Do I simply split the front to rear brake line and introduce a cylinder of some type, with brake lever, or is it more complex? What type of brake cylinder is recommended and where from? Is there a ratio between the bottom pivot point of the brake lever and the attachment to the brake cylinder or am I over complicating the system? Does introducing this into the braking system cause problems with the overall braking efficiency and also cause the MOT man to have a fit? As you can see I am not quite ready to go ahead with the installation and any help would be of interest. Thanks in anticipation of advice from all you experts!!
