My wife came home the other night complaining about her brakes. She was driving home on the interstate and all of a sudden the traffic slowed in front of her and she had to get on the brakes. She said they were going "thunk, thunk, thunk..." and she said she didn't slow down very fast. Then every time after that for a while, they did the same thing even when slowing down normal and she had to stay way back for fear she wouldn't be able to slow down in time. Then, before she got home, they started working normal. She said she didn't see any dash lights like the ABS light on the dash. I scanned it for codes and it was clean.
I told her that was the normal ABS operation to keep the car from locking the brakes and going into a skid. I am not sure why it was doing it after the first hard stop when she was slowing normal, but it sounded like the ABS to me. She was skeptical.
I am wondering as well. What do you guys think?
I was thinking of going out on the highway and slamming on the brakes to test it. Good idea or bad idea? I would know if the "Thunk thunk thunk...." was indeed just the ABS and if it was working as designed. I just hate the thought of locking up brakes "on purpose".
