Installation instructions for Artikel 915 VW T3 Bus conversion to the Audi ATE 981 982 brake system with 347x30mm brake disc adapter tuning

Here you can find out how to proceed step by step to convert the front axle of the VW T3 bus to the ventilated 347x30mm brake disc including Audi A6 brake calipers.

Dismantling::

Old brake system (brake disc, brake caliper and brake caliper carrier)
Remove or machine the air baffle or brake baffle or armature plate (although we prefer to remove it because the brake is ventilated better).

!!Important!!:

It is essential to check that there are no rust or paint residues at the screwing points of the steering knuckle or the wheel hub. If so, please clean them. Then check the thread of the steering knuckle for damage..

What do you need for this?

Approx. 1-2 hours of time required, depending on specialist knowledge
Torque wrench with matching attachments
Liquid screw lock

First, the Epytec tuning adapters are mounted on the front axle of the VW T3 bus.

Then the 347x30mm Audi A6 brake disc (part number: 4F0615301G) can be mounted on the wheel hub.

Then the ATE 981 + 982 brake caliper carrier from the Audi A6 4F (part number 8E061124B) must be assembled

Next step, the brake calipers from Audi A6 4F must be mounted on the brake caliper carriers. Then you can reconnect the brake lines and bleed the brake completely. With this conversion, we recommended to convert directly to steel braided brake lines.

Here you come directly to the suitable steel braided lines.

These have the following advantages:

no pressure loss when braking, noticeably exact pressure point
no swelling as with rubber lines
save money, because Steel braided lines have an almost unlimited shelf life and do not have to be replaced every 3-5 years

Shorter braking distance
marten safety
optics

Now you can mount the rim again

When you mount the rim, you must ensure that the brake caliper does not rub against the rim. If this is the case, you can counteract this with spacers if necessary, so that the rim has enough distance to the brake caliper. Click here for our spacers (click here)

So the conversion with the Audi A6 4f ATE 981 and 982 brake calipers and matching brake disc is almost complete.

Finally, the freedom of movement of the new brake system must be checked. To do this, turn the vehicle completely to the left and right and check that nothing is rubbing anywhere, or that you are not standing in line anywhere, e.g. on the ball joint, wishbone, etc.

The assembly must be done in the sprung and rebounded state.

If there is a collision when the steering wheel is fully turned, you can easily counteract this with steering angle limiters (click here for our steering angle limiters )
