Probably still have air in the lines. You may want to purchase one of the one-man pressure bleeder outfits. How they work is to force fluid into the bleed valves, thus filling the calipers or wheel cylinders, then pushing the air on up the line to the master cylinder, where the air has a chance to escape-out the top of the master cylinder.

Did you put fresh fluid in the master cylinder? I really think you still have air in the lines. To bleed manually, start with the bleeder the greatest distance from the master cylinder, car running, helper pushing down about half way on brake pedal and releasing 3 times, on 3rd time, holding pedal down to half way depressed point while you open the bleeder valve. Repeat until you are sure all air has been flushed out. Check master cyl reservoir level often, because if it gets low and you **** air into the system, you have to start all over again. Go to wheel next greatest distance from master cyl, repeat above, working your way to wheel closest to master cyl last.

You can adjust the shoes outward on the rear by removing the wheels and drums, then above the axle but below the wheel cylinder you will see an arm that is horizontal, pushing both of the shoes outwards. There should be an adjustment nut that you can turn to extend the arm to push the shoes out.

Did you adjust the rear shoes out? If the rear drum brakes are out of adjustment they will give you a lot of pedal travel. If the pads are worn have no fear of that U-CLIP brake spring, just change one shoe at a time. Take the spring off one side, change the shoe, put the spring back on the post and do the same to the other shoe, no problem.

So long as the brake booster is working, test it by turning on the engine, press the brake pedal all the way down, then shut off engine keeping your foot on the brake pedal, if the pedal comes up slightly pushing against your foot then the booster IS working.

Did you BLEED the brakes??????

DEPENDS WHAT PROCEDURE YOU USE TO REPLACE THEM.IF YOU PUSHED THE CALIPER PISTONS IN WITHOUT OPENING THE BLEEDER AND USING A **** CLOSED THE BRAKE HOSES YOU MANAGED TO SENT BACKWARDS THE FLUID INTO THE MASTER CYLINDER WHERE IS THE POSSIBILITY TO CAUSE THE SEALS ROLLING IN AND ARE NOT HOLDING PRESSURE. THE OTHER REASON IS EITHER YOU NEED TIME UNTIL THE BRAKES BED ON THE DISCS SURFACES.

Spongy brakes could either a piston leak which would be visible or the master cylinder which you may not be able to notice. I would say the latter is more probable as the fluid can pass through inside the master without leaking. Usually you can purchase kits for them although some models are sealed units. The squeaking you are hearing could be the wear indicators but I am assuming you put new pads in. If not then I would advise you do. If you have then check there is clearance between the wear indicaters and the disc you can bend them out if required.

bleeding hydraulic lines is tricky. get someone to help you. get a big bottle of brake fluid, and don't be stingy.it takes a lot of pumps to pass air from front to back of truck. start at the furthest wheel and bleed first. use a clean water bottle punch 1/4' hole in cap use 2 ft of clear 3/16 tubeing, stick it in the cap and submerge in the water bottle which you will fill 1/3 with brake fluid. by submerging the end of the tube this will allow air to bubble out, but it will **** fluid back.you can see the air bubbles come out. All the while someone keeps an eye on the mastercylinder, do no let the mastercylinder run out or you will pump new air in....keep toping off and pass plenty of brake fluid. You will end up with no air and brand new brake fluid

Try checking the caliper on the side that's wearing down faster. Make sure the caliper seal where the cup is does not have any damage. But it might be due to the fact that you only bled 3 out of 4 lines. Good Luck And PEACE
