Yes there is but have the rear rotors been removed to see if the e-brake shoes are out of adjustment or severely worn? These trucks are known for the e-brake shoes to wear prematurely or just become out of adjustment.

The answer I was looking for is how the tension is increased. I was told by a dealership it couldn't be done ?

And Yes the pads have been replaced. The drums are good too. I was told I had to replace the cables because they were stretched out and there was no adjustment?
