126 Brake Rotors
 

How do you remove brake rotors? I went to replace mine and they are a little different than what I've worked with in the past. Do you remove the little hub cap on then end (that the tire sits on while you screw it on) or what? I'm at a loss here. Much appreciated!

allen bolts from the back, threw me the first time too.

Front or rear?

oops your right, above post was for the front. I havent done rear ones yet so I cant speak to that

You have to remove the hub lock-bolt/nut on the end of the spindle under the grease cap, then disassemble the entire hub/bearings/seals, separate the two pieces (rotor from hub), put back together with new rotor, re-pack bearings with new grease, install new seals, and re-install the unit on the spindle, then tighten the locknut back to exactly where it was before, and tighten its little allen bolt to lock it in place. Then put some extra grease around it/in the cap, re-install grease cap, re-install brake caliper with new pads, and then re-mount wheel.

Nice and easy! Only takes hours! :D :D ;)

I imagine I could do one in about an hour. First time would take twice that maybe. YOu need a large allen socket and a half inch breaker bar to remove the six allens per side on the rotor. They are really stubborn, you have to get the socket seated and nice and straight and then pull really hard to break them loose. Put the rotor in a vice or bolt it to a wheel. I have a vice and use that.

Good luck.

Its not difficult but it is physically demanding.

Find out the recommended torque (100ft/lbs, I think), and torque them in the familiar star pattern. Wouldn't want brand new warped rotors, now, would you.

Five. (The difficulty of the job just decreased by 17%.)

Six rotor bolts would be an interesting fit with five wheel bolts.

How do you get that spindle cover off? Just clamp it and turn or what? The last thing I want is to break this thing off and then not be able to replace it.

You can grab it with a big pair of pliers. Or tap it off with a hammer and drift. It's just a friction fit.

So I might as well change the bearings while i'm at it huh? Does anybody know exactly how much grease to pack into those things? I've heard and read conflicting opinions on that matter. Would too much grease hurt?

Doh!

of course. What was I thinking? Six sides to an allen?

A large screwdriver inserted and twisted works too.

I would not replace bearings that were not giving trouble. I would just clean and lube them and reuse. It is not likely that replacement bearings will match the quality of the oe.

The original bearings in my 300D were made in China.

So I suppose you could say that the quality of the replacements didn't match the original. Hopefully, the replacements were a big improvement.
