Mechanical Brake Indicator Mod?

It was partially because of that vapor-product that I built my own.
The coastal one likely works similarly, given what few hints Dave
has dropped about his prototype.

The easiest way would be to put a pressure switch on the hydraulic brake line for the front tires. It would turn on a light or sound a buzzer. Id prefer the buzzer at first so I could keep my eyes on the road and train myself as to when the mechanical brake is actually engaging. A super loud vibrating buzzer in your seat that feels like being electrocuted for wasting energy, lol

 

gen 3 accomplishes that with the hsi. foot more accuracy, scan gauge

 

scan gauge

 

The scangauge gets its data by repeatedly asking questions on the car's diagnostic bus, and getting answers back. You can have it ask questions about the brake fluid pressures, or the total braking torque being requested by the computer at any time, but you won't have an instantaneous display; it will be lagged by the delay between the repeated questions and answers.

When hobbit built his LED brake-pressure monitor, I think it was because he really wanted to be able to see what was happening as it was happening.

 

The pressure switch would barely change the volume and won't cause a problem with the actual movement of the piston or directly cause uneven braking. I loosened the bleeder valve and let out quite a bit of fluid while someone was holding the pedal and the computer got upset even though the key was off. After that the computer refuses to send brake fluid pressure to that particular wheel because it sensed the large leak that I caused. after a test drive it still wouldn't work. I had to reset the brake computer to restore fluid pressure to that wheel. I certainly wouldn't want this happening because of my added pressure switch. I think it'll be okay because there are bigger natural variances in the mechanical hydraulic braking components
I propose I test it out myself and report back.

 

The beauty of hobbit's mod was he just tapped off the voltage from the pressure transducers that are already built in—and those are analog transducers, not just switches, so the brightness of his LEDs would tell you something about how much pressure was being applied.
