A freind of mine is going to help me do an on car rotor turn and it's the type of set up that bolts onto the caliper mounting points with the FX up on jack stands and then use power of the car to do the turning.
My question is-- Will the AWD system in the FX turn each wheel independently so we can use this rotor turning method?
 
I believe the wheels don't turn independently. It's more like power distribution per wheel. I am not an expert on this. Let's see if Jeff or John has more knowledge about this one.:tongue:
 
dude, I think your mistaken. every on car brake lathe I've ever seen includes a motor that attaches to the studs to spin the wheel... if you only have the cutting tool that mounts to the caliper boss then you only have half the setup... what your talking about is impractical... it would not work on front wheel drives for the rear, rear wheel drives for the front, & not to mention that most cars have open diffs...
 
I'll check that out with my buddy but I'm sure he said that this particular set up uses the power of the vehicle to operate it.

Instructions from the Kwik-Lathe 108​

TURNING THE ROTOR​
[/FONT][/FONT]
1. With the transmission in neutral or park, start the engine and warm up the vehicle until the
idle is at service manual specifications. Keep foot off the brake pedal!​
[FONT=Arial,Bold][FONT=Arial,Bold]
NOTE:​
​
[/FONT]​
[/FONT]-If a Power Drive (Part Number 108-0004-02) is used for this operation, refer to
the Power Drive operating manual for proper procedures.
2. Vehicles with manual or automatic transmissions should be placed in 1st gear unless
directed otherwise by the vehicle service manual.
3. Turn the power feed motor on and snap it in place. There should now be tension on the
drive belt and the hand wheel should be rotating.
4. Allow the Kwik-Lathe to feed out until the tool bits are off the rotor surface. Switch the
power feed off, shut the engine off, and now examine the rotor. If the surface is smooth
and satisfactory, repeat the operation on the opposite side. If the surface is not
satisfactory, then feed the tool bits back to the inside diameter of the rotor and repeat the​

turning operation. DO NOT TURN ROTORS BELOW MINIMUM THICKNESS.
 
oh, I guess I've always seen them used with the power drive... it makes sense if the wheel can also spin under it's own power it should work the same I guess...


I know I've had my fx up on a lift & in drive & have had all 4 wheels spinning at the same time, not to sure what would happen if you had 2 wheels still on the ground, but I think if you get all 4 off the ground it may work that way? only thing is, not too sure if the lathe resistance would cause the wheel your trying to cut to stop... might be worth a shot to try it...
 
Supposed to give it a try this weekend I'll let you know how it goes.
I'm going to have it off the ground all the way around and have VDC Button off and SNOW buuton on.
 
on many open diff cars if you try to stop one wheel you can, & the diff will just make the opposite wheel spin faster... a posi rear or a limited slip diff would of course not allow this to happen but we have neither... also wondering if the lathe may even just slow down the one wheel a bit while spinning up the other... if that happens it might kick a slip light on... good luck with it, can't see it hurting anything & I guess theres a good chance it'll work fine.... if it doers kick a slip light but still powers the wheel through the cut you should be fine to continue on like that, once all done & on the ground it should straighten itself out & slip light would go off, no computer reset or anything should be necissary I think...
 
On Car Rotor Turn

Eveything wofked great had two warped rotors causing brake judder and steering vibration between 40mph and 60mph--All good now yea! Here are a few pics of the on car rotor turn powered by vehicle.----

The brake lathe attaches to the caliper mounts and the hub nuts were torqed to 40lbs to hold the rotor in place--

Then we clamped the caliper piston to keep it from popping out---

Then we clamped the brake pads to the oppisite side rotor to lock it---

Then we started the FX and put in 1st gear at an idle with VDC off and turned the rotors---

We did all four rotors and they came out great:tup::tup:

Wonder if he can send that brake lathe out around the country like the +2 timing mod Cipher module?

Just kiddin. This takes a bit more time & knowledge. I probably wouldn't try it unless I had help the first time.
 
Exactly. I have the time and ability to learn, so I'd get satisfaction from turning my own rotors if they became warped. Pretty much every rotor I have ever owned has warped in it's life, so I know I'd use it. But I'm sure the tool is VERY expensive to buy. Maybe rent?

Because I have the BBK, I can't use a clamp to keep the pistons from extending, but I could place a block cut to fit between the four pistons. I'd have to figure out how to stop the other rotor from spinning.

Wonder if the lathe blade would care if the rotors are slotted or drilled?

DIY is always going to be cheaper, but you have to know your limits. So far I've done all my own mods except for the springs, transmission and custom stereo stuff, so I feel capable. Not everybody would want to do it, but to each their own.

damn, that's pretty cool, so clamping the opposite side is the key to not having the cut stop the rotor... did it kick on any lights on the dash throughout the procedure? I'd imagine it must have... slip? awd? I'd guess the dash would light up like a christmas tree:tongue:

Pretty much every thing slip,awd,vdc off on but after we were done they all reset after driving about a block. You can get one of these Kwik-Lathe On-The car brake lathes for $ 1410.00
see- http://www.kwik-way.com/products/BLT/108.htm
 
Another benefit gained from brake job was that the new OEM hardware kit and pads had a new anti squeel tab on clip and pad no more squeek while braking when backing up.:tup:
