Chevrolet Repair: cheverolete venture 2003, brake caliper piston, rusty ridge

Question
i just changed my front brakes a month ago. for the past 2 days they are locking after 10 minutes of driving, why? when i push the petal it is hard. i have abs. the light has always been on since i bought it which was 5 years ago..

Answer
HI RACHEL, ABS SHOULD HAVE NOTHING TO DO WITH THE LOCKING UP PROBLEM. THIS IS MORE THEN LIKELY A BRAKE CALIPER PISTON RUSTED OR FROZEN IN PLACE CAUSING THE BRAKES TO HANG UP AFTER THEY GET WARMED UP..DO YOU SMELL SOMETHING BURNING BY CHANCE AFTER DRIVING A WHILE ??? JACK THE CAR UP AFTER DRIVING THIS FOR A WHILE AND USE YOUR HAND TO SPIN THE LEFT AND RIGHT FRONT WHEELS. YOU SHOULD FIND ONE OF THESE WHEELS NOT SPINNING FREELY OR LOCKED UP.. THE WHEEL THAT IS LOCKED UP YOU WILL NEED TO REPLACE THIS CALIPER..WHEN YOU PUSHED THE PISTON BACK INTO THE BORE OF THE CALIPER THERE WAS A RUSTY RIDGE ON THE INSIDE OF CYLINDER,,THIS WOULD CAUSE A LOCKING UP PROBLEM..WHEN THINGS GET WARMED UP THEY WILL EXPAND..LET ME KNOW HOW YOU MAKE OUT AND GOOD LUCK,,,,TOM....
