1992 Acura Integra 4 cyl Front Wheel Drive Automatic 260000 miles
This vehicle is my wife's car, but I have provided most of the care for it since it was purchased new in 1992. I have replaced brake pads the last two times that was required and replaced rotors with Centric Premium rotors and both front calipers with fully loaded Centric quiet stop replacement parts. They work smoothly enough and seem to have appropriate grip, but there has been a new problem we are experiencing since my wife returned from a period in Austin, TX. I noticed the brake pedal seems especially soft after the car starts when cold or after days of disuse, but that seems to go away once the car has been running for long enough to become fully warmed up. Thereafter the brake pedal seems to have the right amount of travel and firmness. My thinking about a master cylinder failure (I replaced once previously around 110,000 mi) would be that the pedal shouldn't firm up the way this seems to after little more than five minutes, but the soft pedal effect should continue. Coming back from a visit into the nearby foothills today there was an odd grab of the right front brake and a distinct burning smell when we stopped after a few miles along the route home. Acceleration became more sluggish and difficult, the transmission seemed to work extra and shift at a different point, and the brakes were not only entirely firm and responsive to only a slight touch but they clearly were gripping differently. The right front (passengers side) appeared to have locked to where it simply would not disengage after pressure on the pedal was released, and the braking of the one front wheel was enough to bring the Integra to a halt at idle speed and keep it from normal movement forward after full braking when I left the car idle only. That had never happened before while I used the car, nor according to my wife when she used it, either. If there is any suggestion of how to approach repair of this problem, it would be greatly appreciated.
