I have an ST1100AN and my gf bought an ST1100AP couple of months ago. So, there are two ST1100 ABS I's on my hands and both with brake problems. I'm going to repair both systems and I will update this thread always when I have something new to tell. Good tips are also welcome.
Problem list/symptoms:
ST1100AN
-ABS/TCS is not working, ABS 2 and TCS warning lights are blinking and TCS-off light is on. After pressing ABS reset button TCS light goes off but ABS 2 light continues to blink. I can't get a proper fault code from the system. Last codes I saw was 1 blink, "Crank angle sensor" and 8 blinks, rear pulse sensor(?).
-Front brake disc is twisted
-Left front caliper is stuck
Edit: There's also very rough running, increased fuel consumption and engine is running very cold. And leaking exhaust. But main thing is the brake system.
ST1100AP
-ABS is not working, I can't get proper fault code either. After reset the ABS 2 light stays on or blinks.
-Brake hoses are most likely original so brakes feel like an old rubber band.
Edit: ABS 1 light is dim in AP.
