Machining Cross Drilled Rotors

[livicuru]

HI

My rear rotors are crossed drilled and have a bit of a groove on the edge. Before putting new pads in i wanted to get them machined; but they are crossed drilled and wondered if they are still able to be machined to make em flat.................any ideas ?? if so who in sydney does em?? If not why NOT!

[ali-turko]

yes u can

[livicuru]

ah ok; Can anyone else confirm this? I heard that they wont because the machining bit will get caught in the drilled holes and it becomes a pain!

Thanks Ali-turko.....you have done ??

people with brake lathes will be able to tell you.

give these people a call in the morning, ask the question.

[ck_chino]

yes it can be done

i have done both the frt and rears of mine no problems

My compliance shop machined my crossdrilled rotors (front and rear) to pass inspection, rears still look ok but this is what the fronts looked like after 1 track day...

[mad082]

what did they look like before they were machined? if they looked like that before hand and the shop didn't also smooth the pads off then that explains why they look like that now.

also comes down to what the pads are like (quality and compound) as well, because if they are a lower quality then a track day is going to cause wear like that even if you had new rotors on there

Hey guys

thanks for all input. I got in contact with a brake place and said he could machine them as long as they are below the legal limit.

MOODLES" did the compliance dude machine them and then put your old pads back on?? looks like it!

I will be taking mine off and taking them in to machine shop; then fit my QFM 500's.

I have fitted QFM 500 to fronts (without maching disks cause they were ok); but my rear disks had a little lip around the edges......so i though to maching them a little before i put my new QFM's on rear.

But put it this way; with my new 18 by 9.5 LMGT4's (on R32) and new front brakes; Im suprised that its already pulling up better than what ever brakes were on there (bendix i think) and stock rims.

Only problem now is that with 265/35 tyres there rubbing on the rear gaurds ....

......I think i need to roll guards............???????????

machined them because they had rusted up in japan, and yep put the old brake pads back on
