Installation instructions for article 878 VW Golf 4 Bora 1,8T Polo VW Polo 6r WRC Audi A3 Adapter Porsche Cayenne Brake Brake Caliper Rear Axle
Here you can find out what you need to pay attention to if you want to convert the rear axle of all four-wheel drive Golf 4 Bora Vento Audi A3, etc. to the Porsche Cayenne brake system.
Dismantling:
- Old brake system (brake disc, brake caliper and brake caliper carrier).
- Remove or process the air baffle or brake baffle or anchor plate (we prefer removal, as the ventilation of the brake is better ensured).
!!Important!!:
It is essential to check that there are no rust or paint residues on the bolt-on points of the steering knuckle or wheel hub. If this is the case, please clean them. Then check the threads of the steering knuckle for damage.What do you need?
- Depending on your technical knowledge, about 1-2 hours of time
- Torque spanner with suitable attachments
- Use liquid threadlocker / Loctite to secure the screws.
First you have to remove the brake dust plates, as they are no longer needed. Now you have to shorten the cast nose of one of the brake dust plates by approx. 2mm so that the Epytec Tuning Adapter does not protrude and can be mounted cleanly. Unfortunately, there is no other way due to the space conditions on this axle. We recommend that you hold the adapter against the axle once, then you can see exactly which lug is affected and needs to be machined. Only one has to be machined, the others can remain in their original condition.
Now you can mount the adapters as shown in the pictures. You can see how to proceed step by step.
When you mount the rim, make sure that the brake caliper does not rub against the rim. If this is the case, you can counteract this with wheel spacers if necessary, so that the rim has enough distance to the brake calliper.Click here to get to our wheel spacers (click here).
The conversion with the Porsche Cayenne brake calipers and the Golf R32 hand brake system and matching 310x22mm Phaeton brake disc is almost complete.
Finally, the clearance of the new brake system must be checked. To do this, turn the vehicle in completely to the left and right and check that nothing is rubbing anywhere, or that nothing is touching the suspension joint, wishbone, etc. The whole thing has to be done in the sprung and fully retracted position.
The whole procedure must be carried out with the suspension on and off.
If there is a collision at full steering angle, it may be possible to counteract it with steering angle limiters (click here for our steering angle limiters).
