While driving on the expressway, I had to slam on my brakes when all traffic came to a sudden stop. Brakes became very spongy for a good while, but eventually they started acting normal again. About a month later, same thing, only this time the brakes never recovered. had to pump at least a couple of times to get a good stop. Then just a month ago, 5 months after the initial problem, I lost all brake pressure and fluid pours out from the ABS module. Needs to be filled almost twice a day. I do a lot of city driving, so it's always stop and go. Mechanic inspected the system and said it was the ABS module, so I bought a used one on Ebay from an auto parts shop and am having it installed tomorrow. I hope it works.
