AUDI REAR SPINDLES and BRAKES on 02 BEETLE TDI

[dweisel]

What year/model Audi rear brakes will work on the rear of an 02 Beetle tdi.

Thanks

The front wheel drive TT/MK1 (1999-2006) has the same non-vented 232x9 rotors and I'm pretty sure the same caliper/carrier.

Beyond that, there's other things you can "make work", but the above should be a straight forward bolt on.

Yep, FWD first gen TT stuff is the same on the rear, as are all the 4th gen Golfs and Jettas save for the R32 and t he 20AE GTI.

Maybe put context to your question, because I get the feeling you might be after something beyond just what we've said.

You can look at the part nos. for each

So, will the Audi A4 FWD parts work on my Beetle?

Thanks

Well, yes, but I guess my puzzlement is, why are you asking? FWD TTs were not high volume cars, so sourcing used parts from one to go on a NB would be a strange thing to do.

The other way around would make more sense.

Did you stumble upon some weird Audi-only graveyard somewhere?

I mean, a bunch of Telsas use Ford A/C compressors, but I don't think anyone with a Fusion is looking to see if used Telsa parts can be put on his Ford, but I would not be surprised at all if a Tesla owner would look to Ford to source the same part for FAR less money.

I guess it's an OCD thing. I put Audi tt front control arms, sway bar and spindles,plus Bilstein struts for a tt on the 02 Beetle in order to install a Wilwood Big Front Brake Kit.
So, was going the same route with the rears.

Appreciate the info.

Sincerely,

The TT 225 quattro should have the vented rotors, caliper, and bracket that you're looking for, also Jetta GLI and the r32.

When you swapped the sway bar in, do you happen to remember if the plastic pieces were intact on the sway bar by the mounts? Installed a 19mm tt bar on the golf with poly mount bushings, there were remnants of plastic left on the bar and they looked like they might have something to do with centering it

Before you get those Audi TT rotors, check the height of the "hat" on the rotor. I made that mistake once (ordered TT rotors that were the same diameter and thickness and bolt pattern of rotor, but neglected to check the "stack height" (for lack of better term)), and ended up eating the cost on them as shipping them back was pretty close to what my refund would've been.

I don't recall seeing any plastic pieces. The tt sway bar mounts looked the same as Beetle sway bar I was removing.

I don't recall the Audi sway bar mounts having any plastic parts on it. Seems to me, it was the same as the one i removed from my Beetle.

And this wrong stack height caused what problem?

Are you researching vented or non-vented rear rotors?
As mentioned above (& confirmed by OH), the FWD TT rear non-vented brakes are the same.

Where it can get complicated is vented rear rotors. If that’s what you’re interested in we can go down that rabbit hole.

 

[braddies]

Considering the existing brake upgrade up front guessing you want larger rears as well. A brake upgrade in the rear to the larger vented rotors needs the caliper and carriers from a car that came with vented rotors.
Off topic, Just wondering if anyone else has issues with the sway bar being off center, my TT bar seems to self adjust to the left and right even with new mounts.

This post will be specific to the 256x22 VENTED 5x100 rear rotors.

As for rear rotor compatibility between VW Golf/Jetta/NB (MK4/MKIV/A4 chassis) and Audi TT (MK1/A4 chassis).

The same 256mm X 22mm vented is used
The same (functionally) 2 calipers are used (some say 43, some say 38)
Two different caliper carrier geometries are used - 1 for FWD, 1 for AWD

If you try to use AWD carriers on a FWD car rear axle the opening of the pads/caliper will not align with the position of the rotor. But various aftermarket companies make a spacer for this to shift the caliper.

I am looking to install non vented rotors. I have seen track cars with vented rotors that have cracked at the slot or where they were drilled.

The stock rear brakes are the same. The rotors and pads cannot tell what brand car they are used on.

So in this case, your OCD is misplaced.

There are sometimes a variability on the pads, as in some cases the more performance oriented cars might get a different friction material compound from the factory, but the aftermarket won't make that distinction and the dealer branded replacements may not either.

That could be also a function of the location of final assembly. A Mexican Jetta sedan, or a Brazilian Golf, may have both left the factory with TRW pads manufactured in Mexico. But a German Jetta wagon, or a TT from Turkey, or a SEAT Toledo from Spain, may all have used Pagid pads made in France. But if you go to a dealer today and get new replacement pads for ANY of those cars, you'll get a Textar supplied set of pads in a VW box.

But again, the aftermarket won't make any model distinction. Although in this case, VAG doesn't either. I just looked up the rear pads for a 2002 FWD TT roadster, and it lists the exact same 1J0 prefix pads as the above mention VW-branded models. So even from the dealer, either a Volkswagen or Audi, you'll get the same pads, in the same box, with the same part number.

So I guess if you want to brag, you could certainly *say* your car has Audi rear brakes... and if you went and got the parts at an Audi dealer, you may find you'll get to pay more too, as usually they have a higher markup. And if you REALLY want to see a markup, go to a Porsche dealer and price some random Volkswagen part that their models may have (the Cayenne is mostly a Touareg, and the Macan is mostly an Audi Q5). Someone on a forum posted the difference in cost of the cylinder heads for the Q5 and base Macan (both use a variant of the VAG EA888 engine). Same head, same engine.... Audi list is $610 for the bare head (no cams, no valves). Porsche is over $4k.

I am looking to install non vented rotors. I have seen track cars with vented rotors that have cracked at the slot or where they were drilled.

When I say vented, I don't mean drilled nor slotted, but a rotor that is thicker and has internal vents, like your front rotors have.

Across both the VW MK4 and Audi TT/MK1 platforms there is both a non-vented (232x9) set-up and a vented (256x22).
The non-vented 232x9 was only offered on FWD configurations.
The vented 256x22 was offered on both FWD & AWD configurations.

The non-vented 232x9 FWD set-up should be the easiest to fit to your FWD MK4 NB, because they are the same parts that your car would have had originally.

The "key" to converting to the 256x22 is going to be the correct carrier or using the adapters as linked above. Note: for these platforms there are (at least) 3 rear brake caliper carriers FWD non-vented, FWD vented & AWD vented, don't recall if they are R/L specific.

The rotor ends up a few mm or so too far inboard or outboard - can't remember - so the brake pad carrier doesn't fit overtop of it.

The folks above obviously have a lot more experience than I do, so go with them. But I just remember going with TT rotors and ending up with something that didn't work even though they were solid 232mm rotors.

Here’s a good online resource for comparing rotors.
