By just changing the pads, IF you were careful, you shouldn't have lost any brakes function and, in fact, should have had more brake pedal.
First, check your master cylinder to make sure it had fluid in it.
The next step is to bleed, bleed, bleed in order to get ALL the air out of the lines.....that shouldn't be in there UNLESS you blew a cylinder out or took a line loose while you were changing the pads. Don't over look the fact that the master cylinder may have been your problem from the git go. Good luck. Pops

Run thought the basics, check the level in the Master cylinder. Leave the cap off the Master Cylinder when bleeding. Have someone in the car. Start at the back passenger side of the vehicle. Have the person in the vehicle pump the pedal until int gets hard to push then HOLD the pressure on the pedal while you crack the bleeder open, if air comes close the bleeder, repeat the process until all fluid, just open and close quick so air doesn't suck back into the system. Go to the other back tire repeat, Then to the passenger front. your move from farthest line in the system to the closest to the Master cylinder. Less chance of air in the system. If this doesn't do it Your master cylinder is bad. Make sure your cracking the bleeder not the supply line to the slave cylinder or the Calipers or you won't get all the air out.

If you changed the pads only, you shouldn't have to bleed the brakes. You only need to do that when you've opened the lines to the brakes.
When you put in new pads, the cups have to be pushed back into the calipers to fit the new pads in place. So, after your done, you may have to pump the brake pedal to get the cups back in contact with the pads and the pads in contact with the rotor. You should be able to do that with the engine off, or you can do it with the engine running, but keep it in park.
If you don't get a firm pedal within 5 pumps, turn off the engine and pull the wheel and see if you can see any problems with the brakes.
Other then that, it's hard to say what may be wrong, you may need to have your car towed to a shop.

I would have it worked on by a mechanic.There could be
a number of different reasons.The proper way to bleed
the brakes is to take a small bottle and fill it about half full
of brake fluid.Connect a tube from the line into the bottle
and then pump the brakes until there is no air left .Then
you close the valve and pump the brakes until you have
enough pressure.Sometimes you need to be in reverse
and pump the brakes depending on the make/model.

Yes, you might need to bleed the lines but first, when you pushed the slave pistons back into the brake cylinders, it moved brake fluid back into the master cylinder. Typically, the first couple of times you press the brake pedal, not enough fluid is pressed back down the lines to move the slave pistons into the new final positions. The clearances in the hardware; shoes or pads to pistons and rest-stops need to be 're-set'. To get to the final positions the pedal may need to be *slowly* depressed full stroke and slowly released and pressed again several times. Then the pedal can be 'hard'. The last thing I do is press very hard to insure the integrity of the lines, bleeders, and lines.
Make sense?

Forgot to bleed the brake lines!!! Or, if you did then you might have air in them!
If that's not it... Then there might be something wrong with your master brake cylinder...? Did you pump the brake pedal all the way down when you were bleeding? Well you're not supposed to.

sounds such as you want a front end alignment to me. probably you apart from could have air interior the gadget attempt bleeding the brakes returned. Did you bench bleed the grasp cylinder? If no longer you ought to have air interior the lines additionally what shape have been the rotors in?

before bleeding the brakes try pumping them for a while. (pushing the pedal all the way to the floor and letting it come all the way back a few times) The caliper you compressed to make the pads fit on sometimes gets stuck compressed.

as was just said..if you change pads..bleeding is not necessary..did you check the brakes in the back..are they adjusted up properly..any good brake job should include a clean and adjust on the rear drums..if they are drums in the back..One good way to figure out if it needs to be done is to try to take off the drum..did it come off really easy?If it did it needs to be adjusted...
Another thing is were the caliper sliders properly lubricated?...check these out before you start bleeding..its worth looking into..

Do you need to bleed the brake lines?
