ABS PROBLEMS

[Keith Sturtz]

MY ABS system when start up car pull out and hit brakes you get a Spring 
effect (brakes lock thing pop loose sprung feeling at brake pedel)ABS 
system shuts off and  stays off if you dont hit braks soon after start 
no ABS system will just shut off after a few if you turn on abs system 
at switch and hit brakes right away you will get the same spring effect 
and by the way the car will not  come to a stop very fast so if i pull 
out right after i start car and have to slam on brakes to try to avoid a 
acadent im outa luck.
I have replaced all brakes , Cleand the abs sensors, and replaced the  
ABS relay .
