Hi guys.here is my short story :just had my both track rods replaced a few weeks ago and after that my abs and asr warninh light came on.I've been driving with the lights on for a while but now no lights on but i got this grinding feeling on the break pedal just before the car stops.

Any suggestions?

If you don't know then I would suggest you get them looked at before you drive it much more as they could fail.

A broken abs sensor mine did this only at low speeds though I found check if the plug has come off or any broken wires where they haven't located then properly

yes, ABS senzor failed
