last summer I swapped the front rotors/brakes to powerstop ones on my wifes Dak, brakes were good but not great... flushed the lines with fresh synthetic fluid and still acted the same. talked to some techs about it and one of them suggested adjusting the rear brakes. found out that there is an access port on the back of the rear drums. poped off the little rubber gromit and there's the rear brake adjuster. cranked it down some and took it for a spin and wam, nice brakes now. I think I adjusted it a little tighter in there as well but what i'm getting at is if your brake suck check your rear shoes for adjustment. this took me about 5 minutes to do with a small screwdriver.

 

Yup. I need to check mine out. The brakes on my Ram are way more responsive, but I just put new shoes in and adjusted them.

The other thing to consider is getting braided stainless brake lines to replace the OEM rubber stuff. As it gets hot (or old) the rubber can stretch, so you lose brake efficiency.
