Close! Add to that 280mm and 256mm.Originally Posted by dylan8
there was only 3 sized brakes for the mkivs from memory. 288, 312, and whatever the R32 is.
up too 2lt came with the 288mm
312mm came on the 4mos, gtis, maybe V5s?
from memory anyway! dont quote me
Don't try and use the Bendix catalog. We don't. The only people who can rely on the Bendix catalog is mechanics who only service Commodores, Falcons and Camrys...
Thanks mate!
Without being rude, I doubt it. Warping just doesn't happen, it's probably the biggest fallacy in the automotive industry. The sensation of 'warped rotors' is something called disc thickness variation (DTV), which is uneven pad material being transferred to the rotor, generally caused by cheap crappy pad material, dirty mounting faces between the hub and rotor (very common!) or excessive wheel bearing float. On the VERY rare occasion that a rotor has warped, it's generally due to inconsistent or incorrect wheel nut torque.
Some light reading on 'warping':
-Warped- Brake Disc and Other Myths
- VW OEM are typically very soft, and made to wear, as well as being made to a price. Generally the quality of the metal used is good, but the overall finishing probably isn't as polished as something like an Australian made DBA.What differences are their between OEM, DBA and other brands ?
- Australian made DBA (All 4000 series, 5000 series, and some street series) are a high carbon content rotor, so tend to last a lot longer than the OEM equivalent, with no loss in performance. Of course the price reflects this. Also, 4000 and 5000 series DBA are heat treated prior to final machining, to relieve stresses, so it's virtually impossible to get any heat related distortion once fitted.
- RDA, and all the other cheap generic trade servicing rotors (think Protex, Powermax, BPA, IBS, Calibre etc.) are just cheap crappy Chinese metal made to a price that mechanics can buy for 3/4 of SFA, and make lost of money on them. They don't care about life, as the sooner the wear, the sooner the mechanic has to replace them. Now, I'm not in any way bagging out these rotors, we sell HEAPS of RDA rotors, and have never had a problem, but just keep in mind, they're not as finished or well made, as something like a DBA or Remsa rotor, and generally won't perform as well or last as long as them either.

Knowing what size rotor you've got on a VW/Audi is very handy as it will tell you exactly which pad you've got. VAG are very good at matching the different pad to different rotor sizes. If we're unsure of which pad a car has the first thing we'll try and find out is what size rotors are on the car.
