i installed a drag turbo kit on my friends 95 teg, after 2days his brake start to knock up. at first he thought it was the wheel bearing becuz it was going out anyway. so replaced that. well didn't solve the problem. so i checked it for him. both of his front brake locked up after a short drive. u can release the brake fluid then it'll be ok for little while then it pressurize again. the back brake is fine. they are free spining.
so onlything i can think of is master cylinder or brake booster.
i m also wondering will the boost be a problem?? may be the check valve is not work? i didn't mess with the brake booster line or anything i left it alone the way the factory set.
