Spongy Brakes on 1995 Toyota Corolla after changing rear drum brakes?

My Husband and a friend just changed the rear drum brakes on my 1995 Toyota Corolla and now the brakes feel spongy and the emergency brake does not work. He thinks that maybe the star aligner might not have set properly and the front brakes are what is causing the sponginess. I know that the drum brakes should not need to be bled but do we need to bleed the front brakes anyway because we changed the rears? The front brakes were changed about 18 months ago.|||Well... if they didn%26#039;t touch the wheel cylinders back there, there shouldn%26#039;t be air in the system. When you hold the pedal to the floor, does it slow sink down towards the floorboard? If it does, you%26#039;ve got air. If not, I would try adjusting the rears. Drums are a PITA...|||sounds like you have a broken break line in the back or they probably didn%26#039;t bleed the breaks.|||Sounds like air in the brake lines. I would suggest bleeding the system.|||http://autorepair.about.com/od/troublesh鈥?/a>|||You need to bleed the air out of your system and it will solve your problem|||%26quot;spongy%26quot; brakes mean there is air in the lines,bleed BOTH the front and rear brakes,if you opened the master cylinder/fluid reservoir,you could have inadvertantly captured air in the system.Did you %26quot;adjust%26quot; the rear brakes when you put on the new drums? You should have adjusted the shoes so that the pads gently scrape against the inside of drum when slipping on the new drums,if you didn%26#039;t do this, you need to re-do it.|||The shoes can hung up sideways, you pull %26amp; yank. He probably jarred %26amp; aggrevated the wheel cylinder internally, from the outside pins, making it leak internally. It sounds like he did more than change drums. He probably changed shoes also. There are adjusters %26amp; lots of parts that move. It may not have been put back together right.
