I had problems last year In the summer with my brakes being very weak after making a hard stop from high speeds. They would go back to normal after awhile. Yesterday I made a hard stop and while about to make a turn I had the brake pedal maxed to the floor. When I stopped safely I smelled the front brakes burning, the rear was not burning and ABS was not activated as there was not enough braking power. I replaced the front pads and rotors 2 months ago with Duralast GT pads and rotors, the best pads AutoZone has. But still the problem occurs when you make a hard stop. I'm pretty sure I need to have the brake fluid flushed as mine Is black. But wondering If anything else can cause this. Thanks.
