Is this an easy job, or should i take it in and have done. I have changed front pads, but never the rear.

 

You can take off the drum and look at it. They're not to hard if you can understand it

 

take a good look at it i just put new pads on mine but they still didn't work as good as they should . After looking at the two adjustment cables in the back, i still was able to tighten them as far as they would go and it still wouldn't lock up. So I removed the cables and removed the one bolt that holdes the arm in place. then you can slide it off and adjust it back about a 1/4 in. (they both have teeth on them so you can move them back) so now it gives me more room to adjust the cable. Worked great !!
P.S. This was the first time i did the back brakes and it wasnt that bad.
