brake adjustment

[bill-e-boy]

hopefully yall can see this pic -

I read on here about the adjustment screw - in the pic is the "rubber boot" on the bottom of the brake drum / wheel assembly - is that where I find the brake adjustment screw? I just pull that boot off to find the adjustment screw?

this is on my 06 cc iq ds - recently lifted (6") and the brakes have alot of play in the peddle - brakes don't engage until I push down hard. Before the lift I had real good tight brakes. all the lines and connections seem fine.

thanks
