Originally posted by normhead These days my rotors are replaced because the whole brake assembly comes as one piece unit. Need new brake pads? You get new rotors as well.
The rotors and calipers on the Ram were original, twenty years old with just over 140,000 miles on them. I slipped in new pads at about 80,000 miles. The rotors wore down about 1/8" in the first 50,000 miles or so, then gave up little after that, and stayed true with negligible runout right up until the right caliper hung.
My plan was to change out everything at 150,000 miles.
It just happened sooner.
I should be able to get to 200,000 miles before needing to drop in a fresh set of pads.
The rear brakes are drums, and show very little wear. It may be well over 200,000 miles before they require anything more than bleeding fresh fluid through them.
