Brake switch PSI ?
Clifton:
Has anyone dealt with a brake pressure switch that took too much pedal pressure to close the contacts? A casual stop is not enough on mine.
I can't find at what pressure these close at. I ordered a new one today and I will bench test both but I'm curious if this is common when they fail or do the just not work when they fail.
BDA:
I had to change mine (from the original) but it's been a while so I'm not positive the failure mode. I think the brake lights would fail to come on. If I remember correctly, you could be experiencing the same thing. I just get a new one (3/8 - 24 thread) from any parts place and my brake lights work now.
SwiftDB4:
I got fed up with the hydraulic switch not activating with light pedal pressure so I fabricated a mechanical switch activated behind the pedal.
Clifton:
Thanks BDA and Swift. I thought about a regular pedal switch. If I can just swap and be done it would save extra wiring.
New Lucas one is on it's way. I'll post what I find between the two.
Clifton:
New Lucas switch takes between 80-100 psi. I don't know what mine on the car is closing at but I think I am going to add a micro switch at the pedal rather than swap and bleed to find it is the same set point. I want a brake light as soon as the pedal is moved not 100 psi at the rear brakes.
