Obviously as you all know I'm new to the grand prix scene. Lol ok a few days after I bought the car the brakes started squeaking well I assumed it was the front well my husband assumed it was the back lol come to find out it was the back driver brake the only one lol well we went and pulled the tire off the back driver and come to find out the brake caliper bracket slider Pin had seized inside the caliper so we replaced all that and brake pad. Yay no more lights! But here's the kicker... Today every time I touch the brakes there is a a feeling that comes through the break pedal and than the low trac light comes on but when I release the brake Pedal it goes off! Now this morning when I would start my car ABS light and check tire pressure light comes on! someone help please!
