Just a question for those who have either experience or had done work to disassemble front brakes, rotors and hub:

If you pull either front wheel off, you'll see the hub and behind it the rotor. There are about 6 bolts that run into the hub and either through or into the rotor. What you see of the bolts are the fixed end nuts. Question is, do these bolts run through the rotors and ultimately bolt into something else behind the rotor or do they bolt directly into the rotor itself?

I'm trying to resolve this issue of my mysterious extruded bolt and need to understand what is stripped and be prepared with parts. So, it's either the bolt is stripped which is easy to replace. Or, it is what the bolt screws into that is stripped which I am trying to figure out what that is so when everything is disassembled and repair is needed...parts are known ahead of time.

Also, just how important is it to use caliper grease when a shop replaces brake pads? Whether it is required or not? If they don't use grease, what is the downside?


Any help would be greatly appreciated!!!!!
