when i apply pressure on the brakes, its really hard to press down on them just to get the car to stop. be it at 10 mph or 40 mph. the rotors are new, like 8 months old, pads were changed at the same time. 94 teg, and i checked all the brakes, lines and rotors. mstr. cyl?, or do i need to change the brake fluid and bleed. or is it something that i'm not seeing?
