i have a 1999 300m, and im noticing you have to press really quite hard on the pedal to stop quickly. the only other cars i have much experience driving are smaller. (ford focus, saturn l300) and were light so stopped easy. or they were new cars (KIA optima) with way over-boosted brakes. Anyway, its winter now and i'm in Canada, so its not exactly a big deal if braking force is down, because if anything it helps on ice. but during the summer on a dry road, even if I'm standing on the brakes, I MIGHT be able to get the wheels to just chirp as i slow down. certainly not enough that my ABS has to engage though and its a little concerning because it makes quick stops extremely difficult. Now, I don't know what this car felt like new, but are the brakes always like this? i replaced the rotors and pads myself and it helped a little. but im thinking maybe worn out expanding brake lines or the brake booster? does anyone want to back me up on that? or do you think calipers? even with new pads and disks i still need to literally stand on the pedal to stop fast. Oh I saw some vented Disks for the 300m, I like the looks of those.
