I've had this car for 2 years. The brakes worked fine, good stiff brake pedal. I recently changed the brake pads and found my rear driver side brake caliper was not working at all. I replaced the caliper and bleed the brake lines, now i have less brakes than before. What could be the possible problem?

    You need to be absolutely sure there is no air in any of the brake lines, and make sure the calipers and pads are operating freely. You should use a pressure bleeder, or other type that prevents the brake pedal from being depressed, this can cause damage to the master cylinder and give you the problem you are experiencing. Also, different pads have different stopping ability, and the rotors should be re-surfaced before replacing the pads. If the new pads are used on rotors that don't have a flat surface, you can experience a low pedal as well.
