We have a 2010 BB Vision that we just changed rotors and pads all the way around. ABS tone rings were messed up. After this work the brake pressure light has come on and the pedal is spongy. The system was not opened, i.e.: no bleeders cracked or hoses/lines replaced. Any ideas on what may have caused this condition would be appreciated.
I would bleed it out. Also, I have started to open the bleeder on the caliper when pushing the pistons back in to accept the new pads. This allows new fluid from the master cylinder to make it's way down. You don't even have to bleed the system when you do this. Also I read where the brake system collects 5% moisture per year from condensation (think that is the correct number). So by opening the bleeder when pushing the piston back in I believe I am reducing the amount of moisture in the system.
I thought of the differential switch, so i changed it, didn't matter. we will try bleeding the system out to see if that makes a differnce. thx
When you take out the switch look in the hole. There should be a slot where the switch pin goes. If it's not lined up it pushes in on the switch making the brake pressure light up. I had it happen before on a brake job,I got schooled that day. The hard way.
