Brakes stickin after brake job
Like these guys said we all had to start somewhere and I'm sure all of us are still learning. Also like they said, brakes are the easiest thing to do. Read up on how they work, get the factory service manual and a set of line wrenches.
Honestly you can replace the entire brake system for less than what they charged you, and that's what I think I'd do. I'd pull the parts off that they installed and demand a refund. If they decline submit a dispute with your credit card bank, you'll get your money back.
All new pads/shoes, rotors/drums, hardware kit(s), cylinders, master cylinder, hoses, even lines shouldn't be more than a few hundred dollars if you shop around.
