I have a 95 Subaru Impreza wgaon with all disc brakes. Brakes are mid wear still plenty of pad left, clean clear fluid filled to correct level, rotors in front are spotless and the rear have a little grooving.

Recently during a snow storm I had the ABS kick in and then shut off and the abs light came on. GOt to my destination checked things out couldn't find any issues. Started the car up ABS light is off ABS is working again. This morning on the way to work my brake pedal was very hard with little to no travel and feels like ABS is kicking in on every stop and the pads are slipping, stopping ability and distance is definitely affected. Just went for my lunch and feels like ABS is kicking in on every stop car now pulls a touch to passengers side. Checked all wheel everything was coolto the touch no signs of seized calipers or anything.

Any ideas?

I played around in a uncleared parking lot and pissed the ABS system off a while back. I drove home with the light on and the ABS not working (I noticed I could brake a bit harder, and then the tail end would start skidding). Problem went away after all the snow and dirt got washed out from driving. I can't help but wonder if you might have got dirt or something on one of your ABS sensors.

I would guess a sensor is dislocated or dirty, pull your sensors and take a look to make sure the wires are not frayed and the sensors are securely bolted in place.

Except in some states that won't pass inspection. And it doesn't fix the problem if OP wants the ABS.
then put the fuse back in, or remove the bulb when inspection comes along? It isn't part of the OBD-II system if thats your worry.

Either way, it could possibly be snow getting stuck into the ABS tone rings. Unsure if this would cause the issue, but if it's not one of your sensors, thats one of the last few things that could be wrong.

I inspected it. It looked ok but i unplugged it and the issue went right away so my guess is a faulty sensor. Cars got some miles so its only a matter of time before things fail
