After a hard braking that triggered my ALB on crappy tires last year, my ALB pump started cycling every 10 seconds or so. I quickly removed the relay to stop the pig squeal going down the road. I then ordered a clever kit to exercise the solenoids, did multiple runs of tests and all 4 solenoids seemed to behave normally, fluid is clean. Now the pump will engage briefly when I first get going with the car (once a week on average), and usually won't be heard again on a normal drive, and no ALB light on dashboard. However now the slightest, faintest, most benign intervention of the ALB (like hitting a pebble or two just before coming to a full stop) will trigger the pump, leading me to believe the pressure in the system is not that high. Which begs the question... pressure switch? Accumulator? Solenoids? Thoughts?
