Interestingly I just had to reset my PDWA this week. I had slowed to a crawl at a stoplight, looked left and right for cars and pedestrians, then proceded when a kid on a bike came flying down the sidewalk as I was about to make a right hand turn. I jumped on the brakes, as did he. We missed, I swore, he rode away. (bike riding on sidewalks is illegal here!)
I noticed afterward that the Brake light had come on - obviously the PDWA had shifted. I started by bleeding the front left brake - no luck. Bled the left rear brake and light went out. (I used the left side only for convienience in a one-man operation.). I only pressed the pedal very lightly to recentre the PDWA. I've done this in the past where pumping the brake, as if doing a proper bleed, causes the PDWA to snap to the opposite end leaving you confused as to what is wrong. Moral - look for dumb kids on bikes, and press the brake pedal LIGHTLY when recentering the PDWA.
