Unless you live in the mountains or tow, rotors on most vehicles should last more than 70,000 miles. It is pretty easy to check the thickness of the rotors to see how close you are to needing to replace them. You need a caliper like the one in the picture at the end of this post ($30 to $40 at the local auto parts store). Take the wheel off and measure the thickness of the rotor using the caliper. New they should be at 20mm with a minimum thickness of 17mm. When I changed the brake pads on my Disco at 40,000 miles, the rotors were less than 40 percent worn. Same when I replaced the pads on the wife's minivan at 50,000 miles.

Dealers will insist on replacing the rotors when they change the pads regardless of the condition of the rotors. It is easy money from customers who do not know anything about vehicle maintenance. They don't call them "stealerships" for nothing.

Really 70k+ miles?

You do realize that's very inaccurate. Most rotors on most vehicles today last on average 20-30k miles. Reason being is they are being made of softer and softer materials due to customer complaints of noise vibration and harshness. Brakes in general are not lasting as long as they used to due to the materials they were made of that last a good long time being outlawed, vehicles weighing more, and traction control and ABS systems.

The ABS and traction control systems combined with stability control applies the brakes way more often than vehicles with out these systems. and how many vehicles in todays market no longer come with these systems?

The other thing is why most dealerships are wanting to replace your rotors with the pads. Not only are rotors being made out of softer materials to combat NVH but when the dealerships do brake jobs they incur some liability risks. One of these is the high probability of noise from the brakes while the new pads wear into them. Most people hear a little brake squeal or noise and take it right back to the people that just did their brakes. The dealerships and service people out there know this and want to prevent any come backs. Most layman do not understand that brakes make noise (metallic pads on metal discs). That is probably 90% of the reason most dealerships want to replace rotors vs replace them today to keep the customer from coming back and complaining.

My suggestion is do your own maintenance, none of my vehicles get worked on by anyone unless it is a warranty repair.

 

I've got 2003 R/R BMW done 73,000ks still on its orginal rotors that includes the 1st 20,000ks of towing race cars.
