My daughter has a 2002 Honda Accord. She recently took the car in to an independent mechanic because the car was not braking properly. As she applied pressure to the brake pedal, she needed to push the pedal farther down to get the brakes to stop the car. The brakes finally got to the point where the brake pedal went all the way to the floor and she had to engage the emergency brake to stop the car.
She took the car to a pretty good independent mechanic that we have used for quite a few years and he was not able to fix the problem. Here are the steps he took.
1. Replaced Master Brake Cylinder 3 times with the last being a Honda original part.
2. Replaced and bled the brake fluid several times.
3. Checked and replaced brake calipers.
4. Replaced the front brake system with second hand parts twice.
After and during the above steps, the mechanic tried to diagnose the problem by separately clamping hoses to the front and rear brake systems. While clamped, the brake pedal was firm and did not drop. The brake pedal remained firm when the clamp to the rear brakes was released. But the brake pedal dropped when the clamp to the front brake system was released. Because of this our mechanic is convinced that the problem is with the front brake system. I am not worried about cost yet because he was able to return all of the replacement parts he used except for the Honda Master Cylinder. However, he suggests that the next step is to replace the front brake system with a new Honda brake system that costs $1,000. But if that does not work the part cannot be returned and we will have to pay it.
Our mechanic and his techs have talked to various Honda service people and they indicated that they took all of the right steps. After all this the brakes are slightly better in that she no longer needs to use the hand brake to stop the car. However the car is not safe.
Does anyone have any ideas or had a similar experience before we commit to spending $1000 on an experiment.
One other thing, the car has recently also had some elctrical problems in which interior lights have not been working properly. Could the electrical problem be related to the brake system problem?
