Chipped PCCB - will it still be ok?
Guys,
Whilst not ideal, do you think if you watched the condition of this rotor as it wore it would still be ok given the cost to replace?

Cars that have the PCCB brakes have 2 alignment dowels that screw into the hub that guide the wheel safely home without contacting the rotors. Sorry if you know this. If you don't they should always be used to R&R a wheel, always. Hope this may help avoid another costly disaster. From your pic it looks like a replacement is in order. I've seen ones with much smaller looking chips that have been considered junk. I'm no expert though.

Find out if you can flip it over; or stick on the side you don't see when you get get up. Or just after you turn out the lights..

Thats a pretty big chunk missing... ever seen a PCCB disc fail? Corvette at sebring comes to mind when disc exploded.. which leads to pistons coming out ,no pedal and free trip to tire barrier.

there is no way that can be safe.
picture that rotor spinning really slowly in your head...
now.. imagine the edge of a brake pad as the piston pushes it against that chip...
the chip will be like a pot hole for the edge of the brake pad and will get lodged in there...
need i say more ?
note:
i JUST finished smoking a joint..
and this has to be one of my better technical explanations i must admit.
