2011 Cadillac SRX tight brake pedal
My 2011 SRX has a tight brake pedal after about 3 miles of driving. It seems
to only occur when it has been sitting all day in the summer heat. When the
brakes are applied and the vehicle is at a complete stop the car does not
need the brake pedal pressed. It will remain at a stop until you press the gas
and then a grinding noise occurs. Also the car shakes while this is happening.
When was the brake fluid flushed? You may have to much moisture in the brake fluid. Other problems I have seen are malfunction in the ABS unit, bad master cylinder, bad rubber brake hoses and stuck brake calipers.
