resolved 2001 Brake or ABS pulse noise (not warped roots)
Ever heard antilock brake system make a 4-pulse noise like "urk urk urk urk" that you can feel a little in pedal? I'd like to attach a short & small 4MB video I made but don't know where to put it, lol. It only does it at first press of pedal, about 1/2 second after it's depressed...and every time.
I don't have a brake light on now but sometimes the antilock dummy light will come on and off, or stay for a while.
I don't care if the antilocks don't work because I like all manual old school operation anyway. I know how to drive, lol. But I do want the brakes to always work of course!
It brakes good, straight, quiet and evenly. Fluid is full and doesn't leak out. Seems clean.
Any guesses? Maybe ABS Booster that runs on vacuum...thus the short delay?
There is a small wire on top of the intake plenum that isn't plugged in, but there isn't a male plug anywhere for it to mate with. Took pic of it, and I did get that to attach!
