Replace pads *and* rotors? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Not Boxster related but I figured you guys would know.

A friend of mine took his Tuareg in to have his brake pads replaced (light came on). The car has 40,000km on it. The dealership told him that he has to replace all four sets *and* the rotors. They say they are designed this way. Replace the pads.. replace the rotors too. No exceptions.

Is this true? A load of crap? They want to charge him $1700 CDN. I've never heard of such a thing.

Hi,

If the Discs are cross-drilled, these cannot be machined. with only 40k km, they shouldn't be below the wear limit, but they cannot be turned true, so replacement would be warranted...

That was my first thought. But they're not cross-drilled. And what's more the dealership didn't say that they were worn.. but that they simply *had* to be replaced at the same time as the pads because that's how they were designed.

Hi,

Never heard of that... sounds like some Bill padding to me. Have your friend look up the wear limits for the discs...

Excellent. Thanks Jim. I'm going to do more digging. I just wanted to find out if there was any truth at all to this.

Cross drilled can be machined, but that doesn't matter in this case either way. The only time you need to replace the discs is when they are below the minimum thickness - the hats should have a measurement of what the minimum thickness is, and you can check the thickness with a caliper. If they are heavily pitted, with a significant lip on the edges of the rotors, they need replacement. Normally street pads over 40,000 km wouldn't need to be replaced just yet...
