hi there! a friend gave me a reasonably well kept 92 240 GL sedan, so i'm getting to know the beast. i've worked on motorcycles, but not cars, so this is all relatively new to me.
i'm going to assume this is an issue with the ABS, but here's the circumstances i'd like help diagnosing:
-low speed stopping, parking lot speeds.
-it doesn't always happen, often when the car is still just warming up, or had been parked for a little bit.
-the brakes, sounds like the front ones, make a deep toned springing twanging sound, as if you were spinning a large coil spring in the wrong direction and the spring's end was skipping.
-when this happens, the pedal sinks a bit toward the floor.
-i haven't noticed the abs light going on, but i have to check that the bulb for that light even works.
possible cause:
-someone sideswiped my car when it was parked and really only contacted the driver's side wheel and bumper. they managed to cause the wheel to turn to the right when they hit my car (they were traveling in the direction i was parked).
-i've been reading about abs sensors being attached to the wheel somewhere, and they if they get loose or dirty, they can malfunction and make the car think the wheel isn't spinning. i've also read somewhere that not all of the wheels have abs sensors?
thoughts? steps i can take?
thanks!
