Brake job problem

Ok so I was doing a pad replacement on my girlfreinds 99' sportage

I think my first mistake was opening the lines to push back the caliper instead of opening the cap on the fluid resivor. So, the brakes have no push when i go to drive em I have tried to bleed the front brakes ( usual method, pump, hold, have someone else open the line, let it touch the floor, close the line, repeat) several times on both sides.

Is there something Im missing? Is there a sensor or something that needs to be reset before they will work properly? Do i need to bleed all four wheels at the wheel? Thanks.

Normally you put a clip on the flexible line going back to the master cylinder and then open the bleeder screw to push the piston back into the caliper. You have probably pushed a substantial amount of air up into the line(s) going to the master cylinder.

Does the car have ABS brakes? If so, you may be out of luck without the tool to make the ABS pump motor run while you do the bleeding. If it does not have abs brakes then you may have to use a power bleeder to draw the air out of the system. Normally it's just a bottle or jar with two hoses, one hose goes all the way to the bottom of the jar and that gets hooked to the bleeder screw, the other line just pierces the lid of the jar/bottle and you hook it to a vaccum port on the intake manifold. Start the engine, then crack open the bleeder screw and the vaccum will draw the air out of the system. You should see fresh fluid come out of the bleeder screw within 30 seconds or so.

You should check the back brakes for air as well. Start with the wheel farthest from the master cylinder(usually passenger rear) and work your way forward towards the MC.

Even the ABS Sportages bleed normally. If you've properly bled the brakes and verified you have no air in the lines, remove the cap from the master cylinder and see if they will pump up. I had a Sportage with no braking because the piston had been pushed in and the vent hole in the cap had not been punched out. If your brakes pump up with the cap off, then look down into the little tube on the top of the cap and see if there's a small hole in the end of it near the center of the cap. If not, you can try to use a punch or something to put a small one in.

Frozen bleeder screws are a common issue, next time around unscrew the bleeder screw completely and put a bit of anti-sieze compound on the threads. Alternatively, spray the screws with some penetrating oil(I like the supertech stuff from wal-mart..cheap, and it works) a couple days before you plan on taking things apart.
