I did not check the thickness with anything other than feel and eyes. This is the first set of pads that the car has gone through and they looked good. When I was young and stupid (16), I ate through a set of rotors so bad they almost fell apart when the brake guy did them. My dad was PISSED. Since then I keep a pretty good eye on them and feel for wear pretty regularly.

You muct have some really well calibrated fingers and eyes. Getting a micrometer or calipers to measure the rotors is probably a good idea as it is only 2 mm between new and worn out

You can get a decent digital caliper from harbor freight for around $10-$15 when they are on sale which is nearly always.

I put a washer on both sides of the rotor as I had a little lip and then subtracted the washers thickness to get the correct measurement. In my case, 65k miles and just under 1mm of wear IIRC

No I don't, lol. I will get one of those. I have 80,000 miles on the car, mostly highway as it is my DD, so I wasn't overly concerned. There was very little lip on the rotors, and this was the first brake change on the car. I figured next brake job would need rotors too. Now you have me all panicked.

One step I would have performed. While everything is disassembled spray all with brake cleaner!! Amazing what a difference it makes...

Didn't want to panic you, you are probably fine, its just swag measurements for things like brakes and clearances don't cut it

Get them measured and worst case, you will need to replace them.

I did have to replace my rotors around 80k. I put the caliper on them and they were just under the allotted thickness. Don't panic and remember those wear numbers have some safety built into them. It's a good idea to replace if they are under the minimum spec but I wouldn't stop driving mine just because of that.
