I had a problem stopping slowly at a traffic light where the ABS kicked in the last few meters causing the brake pedal to pulsate. A very uncomfortable feeling. After some research I found that this is a common problem of a faulty sensor or rust causing the sensors to be misplaced. Please advise the age of the car, I figured I could just replace them if I had to bother getting them. After pulling out the old ones and cleaning the old ones from rust, I used these new sensors. They seem to be working fine after 3 months. No more problems with the brake pedal.
