Measuring Brake Rotors
Don't know how you guys do it, but I couldn't figure out how to take my micrometer to measure my rear rotors without pulling the wheels and calipers, as there is now window thru the backplate. So, I made my own window. Here's what I did (please tell me if I reinvented the wheel so I don't waste my time on the front):
After removing the rotor, I drilled a 7/16" hole in the backplate at about the 8 o'clock position about 1/2" in from the outer circumference. After de-burring and smoothing the opening, I replaced the rotor and took the micrometer to the new hole. It worked perfectly. So, I finished reassembling my brakes and tried it again. Worked like a champ. Finally, after installing the wheel, I was still able to slide the micrometer from the backside into the wheel cavity and was able to get an accurate measurement.
The only problem was keeping debris from getting back in between the backplate and the rotor. I feared a rubber plug would melt from heat generated by the rotor and there really isn't that much room between the rotor and the backplate. I thought about just squeezing some silicone and "gooping" up the hole, but I think you can picture how bad that would turn out. Then I remembered using something while remodeling my daughter's bedroom: metal tape. I used it on the heater exhaust pipe and thought it should do the trick. A little bit of rubbing alcohol on the backplate and the tape not only sticks incredibly well, it conforms to the ridges.
I hope someone else can use this or you can feed back how to measure the darn rotor without taking it apart.
