pat, not knowing what I had, one thing i would do is get on a dirt road or some place not to hard to slide the wheels and id find out what each wheel was doing. lock the brakes up, slide the wheels and then get out and see if all of them are working, whether the front and rear brakes are balanced(locking up at the same time), all you would be doing is getting as reading on each wheel and then you will know what to work on. you don't have to get fast , just enough to slide the wheels. if all are working as they should then you will need to put a booster or something else to get it to stop. your front brakes should slide a little before the rear, if they don't that's where the(ATV) comes in. if you are use to power brakes then reg. brakes don't feel to good. do the slide test and let us know what's going on with each wheel. just go fast enough to slide the wheels on dirt now, don't wreck the car.
