I don't know if I'm the only one that has experienced this but I was starting to get squeaky breaks at 6000 km and they felt weak . I looked at the week break problem and found that if you pump them when you start the truck 3 times (only need to do this once) that that it would help with that. It did and the brakes felt strong again and after about 3 month of driving with the brakes working better and feeling like they should, the squeaking has gone away at slow speed. I'm not sure if this is related or not.
