Brakes 4 Less

Had both rear brakes and front rotors and pads replaced. Less than 8K miles later had a pulsation. Took car back to get checked out under warranty. After I picked it up Friday afternoon the pulsation was gone put it had a constant squeak coming from rear. After a few more days the car had a clunking noise from rear and the next day the right rear brake locked up. Took it to a shop near my home so I could walk home and also did not want to pay towing fee just to have manager tell me it was not anything they worked on. New shop told be that the caliper had fallen of . Looked like it wasn't tightened and lug nuts were crossed threaded. WOW! I'll be sure to tell everyone I know not to take there vehicles to Brakes 4 MORE!
