Wet morning, so I put to practice what I'd read in the FAQ about 'exercising' the ALB module - I had experienced the occaisional squeal from the ABS pump on startup.
When standing on the brakes I'd get a very slight snatch left or right then feel the pedal thumping, feeling like it was working OK.
I tried this about 8 times over about a mile and upon the 4th go I started to get a loud rattling/tapping sound from the pump. This would last about 5 seconds.
I reread the FAQ & did not find any mention of the rattling sound, so is this normal and do I have to carry on 'exercising' them until this stops, or have I an expensive problem?!
