esundell90 Posted October 21, 2011 Report Share Posted October 21, 2011 So I have a 90 240 DL. Had a seized pass. rear caliper. I replaced it. While I was at it, I bled the old fluid out, and replaced it with new brake fluid. Now, I know what air in my lines ect. feels like, bled brakes before, this is def. not what's going on. Fluid level is fine, car stops fine, but the stupid ALL GLORY TO THE HYPNOTOAD light won't go out? electical/sensor glitch or is there something else possibly triggering this light?

Three Fat Tigers Posted October 25, 2011 Report Share Posted October 25, 2011 Odds are it's the brake failure pressure displacement switch just needs to be reset. Switch is located in the brake line junction block, as found on non ABS 240s, this is almost directly below the MC, down on the frame rail, access from under the car. Unplug the wire to the switch, unscrew the switch, pump the brakes, reinstall the switch. If any fluid comes out of the block when the switch is out, this will indicate o-ring failure inside the block, best to replace the block, but you might be able to repair it with new o-rings. Doesn't matter what you do with the pedal, just pump it anyway you want, hold it down or not, the number of repetitions shouldn't matter. Though having someone else pump the pedal is better because you will know immediately if the light goes out when you reconnect the switch, and so if it doesn't go out, you can try again without getting out from under the car.
