I installed a third brake light and quickly realized how hard I have to hit the brakes before the lights come one.
I inspected my setup and the PO installed a separate pressure switch in a T on the brake line out to the rear brakes. The switch located on the master cylinder is not being used. What I want is for the system to light when I press the brakes (move the pedal) at all, not wait for pressure to build. Is the switch built into the master cylinder a limit switch or a pressure switch? I may just install a normally closed mechanical switch that is open when the pedal is not being pressed, but I want to ensure the master cylinder switch doesn't do what I want before I go through the effort. Thanks guys, Andy |
