In the middle of trying to replace brake rotor and pads today, never done it b fore, how do I separate the rotor from the hub. Haynes manual says to punch out the hub bolts, which bolts are these?

The hub and the rotor come off together. The lug studs are pressed in on the outoard side. The rotor is bolted to the hub from the inboard side. Get the parts off and it will be pretty obvious.

The PITA part about a simple rotor change is that the hub preload has to be set - PITA but not difficult. You will need a 54mm or 2 1/8" socket to do this. This should help:

Angrybob is correct. The bolts holding the rotor to the hub are quite often a bear to break free... but not stupidly so. And yes, find a 54mm socket and a torque wrench for the hub nuts.

Some say use a screwdriver and hammer... but I prefer to set the preload properly and never worry about it. I also recommend repacking your bearings while the hub is off. Take five minutes, and removes any doubt as to them being packed sufficiently upon reassembly.

Good luck!

Mr.Utah

Thanks to both of you. The hub was hard to get off and I did repack the bearings, really just added a lot more grease. I dont think I did the preload right, I'll just take it off in a few days and do it again. I am still surprised that it takes so much just to replace the rotor. To do the job perfectly, replacing the inner seal and a gasket or two would be in order. thanks

Mr.Utah

I was just thinking, What happens if the preload is not set right? Does it not make a proper seal on the inner bearing?

First you really need to learn how to repack bearings with the correct grease just adding grease does very little.

If your bearing is to loose things tend to start to wobble and break things to tight puts more stress on the bearing causing unneeded heat that can cause the bearing to fail.

This is a simple explanation
