If the pedal only goes to the floor on the first application after you have been driving and seems good for a while till you drive some more it might be bad wheel bearings, with bad bearings on some vehicles it causes the brake rotors to have side movement pushing the pistons into the callipers after driving for a while and when you try to stop it takes one application just to push the push the pistons back out to the point where the pads make solid contact with the rotor.
Also if you have rear drum brakes they may need adjusting.
I'm assuming that the person who installed your parts knows enough to bleed the lines once finished.

It sounds like a pin hole in a brake line. Put the car on a rack and look under it along the brake lines. If one is wet the line has a hole in it. The mechanic should have checked for that first thing. You could have been ripped off. You should have never gotten the car back if the brakes didn't work right.

If the brake pedal goes to floor it could be several causes.
1.air in hyd. system.
2.moment in mechanical system
3.fluid bypassing seals(m/c, wheel or caliper piston / cylinder)
First bleed system either by gravity or pump- and release method.
If still no or spongy pedal than try to isolate by putting vice grips gently but firmly on rear brake hoses and try to bleed front calipers than do the same for rears.This may give you a idea where problem is.
Than i would look for movement at rear.
Ether shoes or calipers could be out of adjustment. To adjust shoes there is a adjuster under drum and to adjust calipers you pump parking pedal to adjust.
Parking brake cables must be free and calipers working OK to do this.If calipers wont adjust they may need replaced.A common problem with GM cars.
Hope this helps and if not email me.

Yes, you have air in the brake system which needs to be bled out or you have a fluid leak in a brake line, brake hose, caliper or wheel cylinder. have someone pump the brake pedal and look underneath the car and see if you have any fluid leaking from one of the wheels or along the frame. good luck

1. low brake fluid
2. fluid leak in system.. air bubles in lines
3. Drum brakes not adjusted tight enough
4. faulty master cylinder (probably)
5. worn out brakes (doubtful)

May be your brake lines have air, verify the brakes' pump and you brakes most need to be bled. You should verify if you brake lines, pump or caliper have a leak.
