Posted about this months ago, but it cleared itself up. Now the problem is back, but a little worse.
After constant throttle at highway speeds for a few minutes, initial braking is nonexistant. Extreemly hard pedal, no stopping ability at all. Let go of the pedal and push again, car stops fine. I suspected it was a vacuum problem, so I checked all hoses for leaks, and checked the little check valve going into the brake booster. All fine.
Now last weekend I almost became intimate with the rear bumper of a Dodge Ram, because the car refused to stop AT ALL. I thought I was going to break the pedal I was stepping on it so hard, and at the last minute, the car stopped. New fluid, bled properly, and new factory pads rotors and tires were installed a few months ago. I had the problem before the brake change. Stop and go driving is fine, no problems.
Any kind of hard stop I can hear the ABS working regardless of pavement condition, which is not common for me to hear.
Im pretty much convinced its a bad brake booster. How hard is it to remove/replace? I would appreciate hearing any other ideas as well.
