ABS acting strange[700/90] posted by John Dillon on

The ABS acts up when i'm driving at low speeds and applying hardly any pressure to the brake pedal of my 1990 740 GLE. The ABS lifts the brake pedal in the same way as if i was locking up. Does anyone have advice as to what i should be looking for? It's no big deal but a bit annoying.
Thank you.

You should remove and clean the front wheel speed sensors. To do this turn wheel full lock to one side and then remove the sensor from wheel that is turned out by undoing a 5 mm allen screw you will see adjacent to arm where tie rod for steering attaches. Then turn wheel to full lock the other way and do the same on other side.
Also unplug and then reconnect the sensor connectors that are in the engine compartment near top of struts. This should effectively clean the connections. This can also cause low speed inappropriate ABS activation.
