I have a 95 GSR w/185000 on it. I've taken good care of the car since i bought it. My problem is after driving for a while my brakes act up. The pedal has a sinking feeling and i get scared so i pump them to stop. I already changed all the brake pads front/rear and changed the fluid in the mc. There is no air in the lines, i've bleed them 3 times thinking that was the problem. Any help would be great.
