R33 Rotors

[sx.]

hey guys just wondering if anyone knows where and how much to get my front rotors skimmed or am i better off buying a secondhand rotors

thanks

[TAKUSHI]

k well i personally would buy brand new ones if i could afford them

If you get your discs skimmed then they're more likely to warp again quicker, because you've made them thinner they wont be able to handle the heat as easy, also if they fall below minimum thickness after skimming then you'll need to replace them

If your going to get 2nd hand ones then make sure they're well above the minimum thickness as they may end up needing a machine themselves

Are you actually getting a pulsation through your steering wheel when you pull up a little harder than usual?

if your gunna buy buy new theres plenty of options for aftermarket discs as for machining any brake shop can do it either in house or know who to send it to

personally i find worn stock parts to be an excuse to upgrade to something better

slotted rotors and race pads yea

[Ehgriez]

rotors brand new are about 400 i think, im not too sure as i usually get it at discount.

im probebly going to ahve to uograde my brakes after i add a bigger turbo so im lookign for something just for the time being so buying brand new rotors seems to be a bit of a waste so im tossing up between skimming them or seconf hand for a couple of months. anyone got an diea of how much skimming costs

[Mr_GaZZa]

skimming 'if you can skim yours is a waste personally' + i think its about $100 to get skimmed! so, i'd get some DBA slotted there only few hundred for a pair... 'try supercheap/repco' and maybe you could just get the fronts first!?!? considering thats where majority of the braking

comes from

$18 ea to machine a rotor .. I have new DBA 4000 n 5000 series rotors instock .. Also have 33 GTR brembo upgrades for GTS-T

Nothing wrong with skimming rotors , i been doing it for 16yrs and havnt seen any thing that can back that claim of " warping easier " after maching

[GTS-t VSPEC]

Yep, nothign wrong with skimming, they won't skim them if there under the minimum recommended thickness, so can't really do it more than once per set.

haha commodores and falcons do it all the time buddy

and just think about that for a sec, the discs are going to be thinner

therefore they cant handle as much heat as they could when they

were thicker, and yes that couple of mm does make the difference

otherwise they wouldnt have such a small margin of wear between

new and throw in the bin, i'd just go brand new or upgrade now

your car will then be ready for more power mods, if not then at least

you know you'll pull up sweet everytime haha

dont think we are driving falcons or commo's.

Umm, sorry, but your wrong, and obviously don't know much about brakes

Skimming is fine, but if you have the $$$ get new discs.

LOL I know commo n ford are bad , When BA was released i was doing 3 - 5 cars a day for local dealership (Ford Aus wty was paying us $200 per car to go n machine oncar ) One car had 4000ks on clock when it was first done ( was only issue on base model brakes n not the premium packages ) , EL - EF have instructions on how to fit seals because if fitted incorrectly it will cause pulsating pedal after few thoasand ks and as for holdens i do average of 5 a week for pulsating pedal .. Have done new Pajeros at 1000 -5000ks old for mits dealer aswell

My GQ wagon is over 2 tonne ( close to 5tonne when loaded with race car n spares) and rotors 19mm thick and has done over 100,000ks since rotors were machined n pads fitted with no sign of pulsating pedal yet im doing commos at 4-60 thousand ks that have been machined ever n rotor thickness of 25mm

Also we had letter from holden saying that doing wheels up could cause them to pulsate and ford gave me a 5 page booklet on how to remove n refit calipers n rotors to try n prevent pulsting problems what a joke

i know plenty mate, im saying a brand new disc will last longer than a disc thats been skimmed, we've had plenty of customers come in after having other places skim discs and what you they're warped again and pal as for me refering to commodores and falcons, brakes are brakes dude, it all comes down to brand of disc and driver that determines the life of a disc, just coz they're all autos

Gwp021 just save yourself the hassle and go buy new rotors, coz if you're going to spend money on oomph you wanna know you'll stop fine, its called piece of mind

[GTS-t VSPEC]

Takushi, That's not what you said, but whatever.

sx, In summary: skimming is cheap, but is only an option if you have enough material left, otherwise new rotors are on the cards.

[R33_NICK]

surprisingly when we skim the rotors and when they come in for their next service, i noticed their rotors needed machining again cause its heavily scored and pulsates everytime i brake and its been done on their last service as well which was like 1 or 2 months ago (the skimming was done properly too and they are not warped). we measure the disc on every services and yeh almost every commodore or falcon we get either needs their rotors machined or replaced.

had my brakes skimmed 4 years ago when i bought my car. had no problems with them since, but are close to needing to be done again.

OK try PERTH BRAKE PART`S in welshpool & have them GROUND ,you should pay about $80 to $100,but it is worth while,

haha oh really??

If you get your discs skimmed then they're more likely to warp again quicker, because you've made them thinner they wont be able to handle the heat as easy

aaand you still manage to repeat what ive already told him

also if they fall below minimum thickness after skimming then you'll need to replace them

um i may not have been clear i am running new rotors ( top level RDA's with braided lines and yellow stuff pads) cause i wanted to know my car could stop right specially with the comp racing i do

what i was trying to point out was that if the choice was made not to machine but to buy personally i'd choose to avoid the issue of using older worn discs that'd probably need machining soon anyhow and buy new

and honestly with what nissan charges it's really worth looking at aftermarket products

cheers

A. TAKUSHI, why did you quote yourself? (Twice)

B. I'm not going to theorise on the implications of skimming brakes, because theorising has already been done...

C. From my 1st hand experience, when i imported my car i was told "all of your rotors need to be skimmed", 3 years later... same rotors, same pads, no skimming, still going (40,000kms.)

Anyway, if skimming was sooooo bad, why would it be an option?
