Bleed rear brake on a 330 trail boss
 

My foot brake(rear) does'nt work. I would like to bleed it but I notice the rear caliper has 2 bleeders on it a left and right. The left sits a bit higher than the right side which is the right one for the foot brake?

Follow the hose back to the master cylinder.

when you bleed the rear leave the cap off the master cylinder.This helps.But dont expect the bleed job to last long.This is a joke of a system.At least the rear works good off the hand brake.
