Also, I found a very useful video of the procedure that will also augment this thread, and thought I'd post a link here. It is on a MkV Rabbit, but it appears (and should be) identical to our B6 rear setups.

Optimum torque. Anyone who has worked on a vehicle knows how difficult it can be to remove a seized nut or bolt. Triple Square is great for high-torque applications. For automotive needs, that means things like drive train components and cylinder head bolts which can be tougher to remove than other components. M14 Bolts (brake carrier to wheel bearing housing): 90 Nm + 90 deg [66 ft-lb + 90 deg] (use new bolts) The views expressed herein are those of the individual contributors and not necessarily those of BRISKODA or SKODA. For general automotive and other uses, it’s Torx. But the versatility of Torx is too hard to ignore. Even when it comes to automotive needs, Torx is simply available in more types of vehicles. That means being able to get a wider array of bits and tools to handle the job. They're known by the Americans as "Triple Square" or VAG as ZXN and are used as they can handle higher torque before camming out.Sizes are M4, M5, M6, M8, M9, M10, M12, M14, M16, and M18. Despite the similar naming scheme to metric fasteners, there is no correlation between the name of the size and the dimensions of the tool.

Where are they used? Triple square bits are typically used for automotive components. They also tend to be found in a lot of European-made vehicles. German manufacturers Audi, Mercedes, BMW, Volkswagen, and Porsche all favor the triple square design. Yes, there is already a great rear wheel bearing DIY in this forum ( http://forums.vwvortex.com/showthread.php?5531205-Rear-wheel-bearing-diy&highlight=rear+wheel+bearing) but things get lost over time (see the doing it wrong thread that was lost a little bit ago) and so I'm posting mine up. If you bought the car used, make sure the doofus before you didn't try to use an Allen bit or a torx bit and mess up the bolt. I've seen that plenty of times. Versatile use. The great thing about triple square bits is that they have a variety of implementations. They work quite well when used with torque wrenches, breaker bars, and ratchets. It is important to note that they should not be used with impact tools, however. Moreover, there are the construction applications of Torx. You can conceivably have an entire toolkit of Torx bits and have a hundred different uses for them. With triple square, you know what they are going to be used for.

To the novice, drill bits all seem the same. The simple fact of the matter, however, is that there are so many different options that it can become confusing. Take Triple Square and Torx screws, for instance. They may seem the same, but there are important differences. anyone tell me the bolt sizes for the caliper carriers, front and rear, the 12 star torx jobs - I want to buy some before I attempt to change the discs(all round) on my pre fl 140 beast, I think hex heads will be easier to handle than the 12 stars, especially on the rears!!

Hook up the VCDS system and retract the EPB piston using the instructions found here ( http://wiki.ross-tech.com/wiki/index.php/VW_Passat_(3C)_Parking_Brake). Heed all warnings. They ain't messin' around. I'm aware that some people have been able to remove the rear caliper with a VCDS system but that seems extremely risky. High torque applications. The reason for the implementation of triple square bits is due to the high torque applications that vehicles can require. When it comes to drive train components and cylinder head bolts, the triple square bit offers a higher allowable torque to remove even the toughest or most seized components.Tamper resistance. Initially, Torx screws were highly tamper-resistant because there were not screwdrivers or drive systems widely available. Since they have become more common, there are variants that are tamper-resistant. That’s a hard question to answer because of the different applications. If we were grading them simply on their qualities, Torx would win based on versatility alone. Torx bits can be used in automotive-like triple squares, but they have so many other applications as well. Greater torque versatility. While it is important that the bit be able to stand up to the extra torque, it is not the only important component. The tool used to do the job plays an important part in getting the job done. So, being able to use triple square with things like breaker bars, ratchets, and torque wrenches gives it the versatility advantage here. The 12-pointed internal star shape superficially resembles the "double hex" fastener head, but differs subtly in that the points are shaped to an internal angle of 90° (derived from a square), rather than the 120° internal angle of a hexagon. In practice, drivers for the fasteners may or may not interchange, but should be examined carefully for proper fit before application of force. A hex key should not be used where a key of square cross-section is the correct fit.
