Sometimes when i stop the breaks stick and i have to push them again then some kind of click happens and they release also when i push the breaks the abs and break light come on momentarily any ideas?

 

When your Brakes Break, they are Broken!!!!
Could be a master cylinder fault or the ABS module/valve assy.

You might flush the system with new fluid to see if debris is clogging something??

ABS relay might have burnt contacts keeping the power brake booster motor from running??

More diagnosis is needed.
