For some of us that bought cars with hydraulic brakes on them reading the trials and tribulations of the mechanicals gives us nightmares. The arms, rods, shafts all have to be perfect not to mention pins and (Pills). Strangely the hydraulics seem to not have nearly the number of failure points but they do have one that can be catastrophic and that's complete fluid loss. (Very rare but possible.) There is one thing that a lot of us lack and that is a proportioner valve to regulate what percentage of braking is done by the front and rear brakes. My question is where did you mount yours and what proportion goes where? Mine work fine, but seems they are equal pressure to all the cylinders which means the size of the bore of the cylinders is what dictates the pressure to the shoes. Been years since I've had mine off yet it seems the fronts were different diameter than the rears. That may make a proportioner a mute point. Any comments? Thanks, not trying to stir up a debate, just curious if I should consider adding to an already adequate system, (39/42 on the front with 43/48 on the rear.)
