92 cavaleir brake/abs problem

i have a 92 cavalier i have been working on for 3 months i changed the rear brakes with cyliders + master cylindar now they won't bleed out i've even had it in a shop they sent it home. help

Take it to a good brake shop. They will have a machine to bleed the system with. They will also be able to find any restrictions in the line or air leaks you may have. Shouldn't even cost to much. Good Luck.

some abs u need to pump them a mininum of 40 times to built up enought pressure. try that if u have not already taken it to a shop. Otherwise do that, the machine i used at school was pretty neat. u just hook it up to my master cyclinder and put the air hose on and turn it on. THen go back and let the air come out. Simple done in like 5ish mins.
