My 80 has been having ABS issues. Started with the ABS activating when I was braking to a slow stop. I pulled the sensors and cleaned them, didn't see anything on them other than grease. That took care of it for a couple days, but now the ABS light is on permanently. I'm going to pull the code and see if the front sensors are bad. My pocketbook hopes not. For anyone that's thought about cleaning the magnets, it's a .5 banana job, here's a couple pics.
