brake chamber leaking from rear when brakes applied

im confused the lines came off of the parking bake chamber there are no ports on the service side. Once i know which line does what (easy) where do they go?

 

perfect!! Thanks will report back tomorrow

 

is the leaking air symptomatic of crossed lines?

 

yes, no explination for understanding dynamics of how leak is occuring

 

so make sure park line goes to port furtherst from service chamber? Service air line to port closest to seevice chamber? Going to attack this mini project in few hours. Thanks for your help, seriously you guys rock.
