Last week I almost crashed... Driving down the highway doing about 65-70 on my way to class traffic was moving normally then all of a started slowing down fast. My accord did not respond the way I would expect; it took forever to stop and it wasn't even an emergency stop. My mirrors were fogged so I didn't have the choice of crossing lanes to avoid hitting the car in front of me. Luckily I was able to downshift (mT) and use my brakes to avoid a crash but it was close enough. I was not tailgating or driving spirited. A few days later and yesterday I noticed that my brakes are not responding the way they used to, they would stop on a dime and now they're not. I checked the pads and they have a PLENTY of life left. Pads and rotors were replaced last year with slotted rear rotors. Any input on this? I have to add that I have a leaking driver side axle, and a leaking oil pan gasket that I haven't got to yet. I don't know much about mechanics but the basic things I do myself. Could my brakes just be dirty? Any cleaning tips.
