Bleed the rear brakes and add new brake fluid. Typically the brakes feeling as if they give too much or "squishy" is from small air bubbles in the brake line...so by bleeding and adding new fluid you let out the small bubbles which cause the squishiness.
When you changed the brakes many people tend to hit the line as well as not clamp them properly and therefore render the brakes "squishy".
Hope this helps.

Only if the rear system was opened where it may have gotten air in the lines.
there is nothing special about the rear brakes, if you have changed any kind of rear brakes on anything else, you will be able to handle the job. if not, spend the $20 and buy yourself a manual.....
manualy adjust the brake calibur on rear brake slot located under rear axles on the inner brake cover.
If it is a Toyota, they do not know how to fix the squeaking brakes either. Even after replacing all the pads and machining the rotors and rear drums
You have disc brakes front and rear. Disc brakes are self adjusting. If the brakes are poor, you have a problem and it needs attention.
You can cutoff the rear brake line. You will no longer have rear brakes and the fluid will leak out. It is not recommended that can't off the rear brake line, without replacing it.
The rear brakes will lock when there isn't enough weight in the rear of the vehicle, the surface is loose (like a gravel road), or they [the brakes] are applied to heavily. Newer vehicles with anti-lock brake systems (ABS) should not have this problem.
Which brakes are you replacing front or rear or all four It shouldn't cost more than $100 with out parts and labor Or you can do them your self it's not that hard at all unless your are doing the rear brakes which will require a special brake spring tool
These instructions are for the front brakes, but they are similar. http://www.hspn.tv/?videoid=44&catid=1
try pumping the brakes up several times hard with the car off start at rt. rear then lft. rear to rt. frt. then lft. frt.
Its been awhile since I've done them. (i have a 2000 s 500) but if you have any knowledge on how to change brakes you won't have any problem. these are probably the easiest pads i have ever replaced.
It may need adjusting. The rear brakes may be excessively worn, and need replacing. The rear brakes may be incorrectly assembled following (in-expert) servicing or repair. A component in the rear brakes may have malfunctioned. The most likely reason is that one of the hand-brake cables is broken.
