Our Venture has 120,000KM (70,000 Miles). I have replaced the front pads on 2 occasions. I took the drums off to look at the rears. (I assumed it would be time to replace them). Although I did not do an actual measurement of the pad thickness when I compare them with the replacements (Monroe brand) they have about 75% left.
I know that most brake wear is on the fronts and that a lot depends on driving habits but this does not seem to be enough wear. I am going to re-build the rear brakes and lubricate the self adjuster and the contact points but I wonder if anyone has an opinion in regards to the light wear I seem to have experienced.
