I know this ABS topic gets beat to death. I searched a bunch of posts back when my brakes failed several months ago. Now they are fixed but I want to make sure they will last as long as possible.
So:
I got my brakes working again (except for the ABS), however the elec motor runs every other time I touch the brakes. Thinking the accumulator was getting weak (and not wanting to have to replace that elec motor again!), tonight I swapped in 2 different spare accumulators I had on hand (one from a Mark7 and one from a Jaguar). The Jag version never seemed to finish filling (maybe I didn't wait long enough?), and the other one charged every time I touched the brake pedal. When swapping them I pushed the brakes repeatedly to dry to drain the accumulator however each one did spray some fluid when being removed; so I know they held pressure, just can't tell how much...
And to clarify, 'touching' the brake pedal to test the accumulator behavior consisted of me standing outside the car, hitting the pedal with one foot, for about 2-3 secs (which is not necessarily equivalent to a vehicle stop).
Questions:
1. Is it normal for it to take 45+ secs for a new accumulator to initially charge?
2. Is it acceptable for it to charge on every other brake application or is my electric motor going to wear out from being overworked?
3. Can a failing pressure switch cause this problem?
