Hi fellas. Wanted your opinion on something. The last time I got my brakes done the front pads were a cinch. Easy to find aftermarket pads, easy installation. The rear shoes were a whole other matter. My independent shop, had to order 3 different sets that their system said matched, but none of them did. They were just barely off and the owner ended up having to go to a Mitsu dealer, pay out the butt for them and measure them there! Mitsu made a barely slight size difference so aftermarkets wouldn't fit! So, in light of this and the fact the front pads do almost all the work. How often should we replace the rears? My shop guy said, 80k to 100k because of the low weight and the fact the rears don't do much. Just stay on top of the front pads as needed, like every 30 to 40k miles. Your thoughts?
