Check your brake fluid.
This car stops like's a dream, and the pedal feels great. What a difference!!
Most people never worry about their brake fluid, and I was one of them. The dealer did a strip test on my fluid and wanted to flush it since the fluid tested bad. They also wanted to do my brakes. $$$$'s!!
Brake fluid attracts moisture, and causes the wet fluid boiling point decreases. The contaminated fluid can also cause rust in the brake lines, and piston bores.
AcDelco Dot 3 is supposed to have additives that helps fight off moisture and corrosion. GM also use's special brake hose's that protect against moisture. I have put my brakes through the ringer and the fluid is over 6 years old, so mileage is irrelevant.
Please people.. get a strip test done and replace the fluid ASAP if it tests bad!
Always makes a world of difference after a few years. Our Envoy was night and day different when I had that flushed with the new tires a few months ago.
GXP's fluid will be done whenever I get around to replacing the rear pads/rotors in the near future. I'm sure it is original fluid. At 101k, it looks like black ink.
