Does anyone have the minimum thickness for the front and rear rotors on an XFR easily accessible? Don't want to wait until the wheels are off to figure out if new rotors are needed. Rather measure them ahead of time and know for sure. Thanks.

 

 

See this page from the Workshop Manual:


If you can't quite read it, the specs for the XFR are:

Front (380 mm brakes) - new 36 mm, worn (minimum) 34 mm.
Rear (376 mm brakes) - new 26 mm, worn (minimum) 24 mm.

 

Are you able to measure rotor thickness without taking off the wheel? I found that the metal shield behind the rotor gets in the way so I've had to take off the wheel to check

 

Correct, you need to take the wheel off to get a vernier caliper on the rotor.
It's not just the splash shields in the way (completely in the way on the rears but only partly on the fronts) but the front rotors are too close to the wheels to fit a caliper through the gap.

 

Thanks so much for the replies. Looks like my plan was bad from the beginning and I'll have to either purchase rotors up front or be willing to be disappointed if the job can't be completed while I wait.

 

Depends on what "the job" is.
If it's simply brake pad replacement then that's an easy DIY.
If it's rotor replacement as well then that's also an easy DIY, just takes a bit longer.
If you can't DIY or prefer not to DIY and you take the car to a shop for either or both of these things and the shop says "your rotors are below minimum thickness and need replacing" then the shop almost certainly would not be able to order new rotors and get them same day let alone in a couple of hours, as not many places stock the XFR rotors. But don't worry too much about that, the specified minimum thickness is incredibly pessimistic, it's only 1 mm of wear on each side of the rotor so even at "minimum" there is plenty of meat left, enough to safely keep you truckin' until you can get a set of new rotors.
All that said, surely you can scrounge up a set of vernier calipers, whip a front and a rear wheel off and measure the rotor thicknesses yourself?
Or else any tyre or suspension shop should be able to do this for you an a jiffy for minimal cost.

 

Really Brian, you know I got all the stuff to do all that? And how easily food can be used to bribe me...LOL Trust me you'll need rotors, I've been shopping them myself.

 

i'd say poke finger through wheel on (COOLED OFF) rotor. if any sort of a lip on very outer edge, the rotor is worn a bit.. 1 - 2 mm of wear isn't much !! any shake in brake pedal? warped and needs replacement. or could be simple pad deposits i suppose. I followed B.W's advise and got the brand he liked - in drilled and slotted. seem to do well. with the pads they supplied, don't bit as well initially as factory (requires more leg) but less dusty and can still activate ABS so I'd say good braking still there. Prob less than $650 for all 4 corners complete with sensor replacements too.
