Default Changing Brake Rotor

Hello,

Can anyone tell me whats the best/easy way to change the brake Rotor?

I removed the right rear tire and was trying to take the hub off to see if I can slip on the new brake rotor...I couldn't get off the center nut which holds the hub on and in the process broke my socket wrinch.

I was looking at the 2 big O-nuts that are on the axle..is that the best way to go instead of removing the hub?

Im limited on tools and don't have a big enough wrinch for that size o-nut..my friend is suppose to help me in a few hours after he finishes work.

Thanks for the quick reply....are you sure i don't need to take off the 2 o-nuts?....it seems that the inner curcumferance of the rotor might not pass over those o-nuts.

well, if i remember its a 17mm nut. so its not rare to find a socket and 3/4" ratchet. it comes off hard but it will come off. when my rotor bent, this is what i did... it was easy.

You need some tools first take off the hub then take a 2.5 allen wrench to loosen the first nut and to take it off use a 2 inch wrench the the second nut will just turn off its two bolts for the caliper and four bolts holding the rotor and your done.

I am trying really hard to get that hub nut off, and all I suceeded was to bust up my hand.....I assume that this nut comes off as any other nut...counterclockwise right?

I had a socket but that also broke in the process. I have a adjustable wrench, but thats not helping much either....am I correct that it's counterclockwise to remove the nut?

take an adjustable wrench that will fit on the 2 axle lock nuts. put a pipe on the end of the wrench and it will turn w/ no problem.. but make sure u take the lock screws out of the nuts before u go turning anything.

im burning up big time

I managed to get the hub off finally with a pressure wrench.

Thinking everything else will go smootly, the damn allen screws that hold the rotor in placed are seized like a mofo All 4 of em!

I've tried so hard by tapping the screws to get them to unfreeze and after trying to unloose any of them with the allen keys that they are practically rounded out. I give the fuk up

allen head screws/bolts should not round out... u must be using the wrong size allen wrench. spray some PB penetrating into it and let is soak...

I used the correct allen head...It seems that those screws are not the strongest quality around..I put some wd-40 thats all I have at the moment.

Going to smoke a Jay and try again later tonite.

I'm betting the screws have loctite on them, they will require heat to loosen them before they can be removed.

I found this out on the axle lock nuts, the allan screws were loctited & I ruined 2 allan wrenches trying to get them off!!!
With red loctite (or whatever the factory uses) you will not get them off with out destroying the screws, wrenches, nuckles, etc without heat!!

A good heat gun should be enough to warm them up, just get them good & warm & they should come loose.

When I changed mine the allen screws were impossible to remove without destroying until I heated them. Get an oxy-acetylene torch and heat the heads up. When they turn cherry red, they come out real easy!!
Just remember to reapply Loctite when you are done

Danger, Danger!!!!
Get rid of the cheap Tiwanese sockets & use the adjustable wrench as a hammer!!!!
Cresent (adjustable) wrenches are only for emergancy use & none of them work as well as a real wrench!!
Do yourself a favor & get some real tools!!
Home Depot, Lowes & Sears have have good tools & have sales all the time, you can get a nice set of basic hand tools with a lifetime warranty without breaking the bank.

Cheap tools will destroy fasteners & cause huge gashes in your knuckles.
You don't have to spend a fortune to have nice tools (unless you must have Snap-On!! LOL)
