Hi everyone, I am new to the forum and looking for some advice.
I have got a very annoying problem with my Subaru Imprezza WRX 52' it would appear that my ABS is kicking in too soo. When I lightly press my break you can hear it bang on literally. If I am on an inclined going downhill and I put your break on when I realise it to creep forwards I can feel it vibrating underneth the peddle. Althought it does not happen everytime I apply the break. I have had it to 4 different people 2 of which were Subaru specialists who do not have a clue what the problem is.

Any advice would be much appreciated thanks :lol:

Are you sure a warped rotor isn't just causing a vibration/wobble feel in the pedal?

If it really is the ABS actuating - is the ABS light ever coming on? If so - the codes need to be read. It's really easy and only takes a few minutes.

I don't like to just throw out possibilities since there are probably dozens but common issues with ABS is a sensor is compromised or a tone ring is bad.

Have you had any other work done to the car related to this area - ball joints, tie rods, cv axles, cv boots, wheel bearings, struts, etc?

also a seized caliper will cause the ABS to come on at the wrong time. Pull the ABS fuse and see if you still have that same issue.
