1990 Accord EX. I just replaced the Master cylinder, wheel cylinders and breaks. I had the system pressure bleed. On the drive home I made a sharp turn and lost my breaks. When I straightend the wheelsI regained pressure. I tooled around a parking lot and lost breaks every time I turned hard and regained on the straight. I am baffled.

 

Is there a drop in RPM's when you turn? Do the brakes go out completely or just work less?

 

There is a drop in RPMs and they work less. Go all the way down to the floor.

 

it sounds like your power steering pump is draging down the car.... make sure that your belts are all tight and your fluid levels are all correct, also check to make sure that one of your brake lines isn't getting pinched when you turn.

 

Make sure your axle nuts are tight.
