i have a 92 sc4 and it has a bad problem with the brakes. I purchased the car this way and this is what it does...When you press brakes they are extremely hard then all of a sudden they are super sensitive. I know its the booster be are there any interchangeable boosters i can use my car is also equipped with trac which makes the ones i found 6-900 bucks. If anyone can point me in the right direction i would thank you greatly

 

sorry moved it to the right section
