Installation instructions article for article 425 VW Golf 5 6 Audi A3 TT Audi on the RS7 356x22mm brake disc with the Porsche Cayenne callipers and the VW Golf 5 R handbrake calliper

Here you can find out how to install the RS7 356x22mm brake discs with the Porsche Cayenne brake system on your VW Golf 5 VW Golf 6 (complete series) with steel axle step by step.

Disassembly:

Old brake system (brake disc, brake caliper and brake caliper carrier)
Remove or machine the air baffle or the brake baffle or the armature plate (we prefer the removal, as the ventilation of the brake is better ensured).

!!Important!!:

Make sure that there are no rust or paint residues on the bolts 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 technical knowledge, approx. 1-2 hours time
Torque spanner with suitable attachments
Use liquid threadlocker / Loctite to secure the screws.

Here you can see all the parts you need to convert the steel axle of the VW Golf 5 and 6 series to the Porsche Cayenne brake system with the VW Golf 5 R handbrake caliper in combination with the Audi RS7 356x22mm brake system:

Rear brake callipers from Porsche Cayenne partnumber: 955.352.421 + 955.352.422 Brembo left: 20.7673.03 right: 20.7673.04
rear brake callipers with carrier for handbrake from Golf 5 R partnumbers: 1x Bremssattel left 1K0 615 423G, 1xbrake caliper right 1K0 615 424G, 2x brake caliper carrier 1K0 615 426
Audi RS7 brake disc 356x22 mm partnumber: 4G8615601 4G8615601E

In order to install the Epytec adapter on the rear axle of the VW Golf 5 and VW Golf 6 series with steel axle, the screw of the rear shock absorber must be removed. Then use the 2 long screws to fix the Epytec Tuning Adapter without tightening it completely.

Now the centring ring can be pushed onto the wheel hub.

In this case, the Porsche Cayenne brake calliper has only been fitted as a test. When the brake disc is fitted, the Porsche brake calliper must be removed again.

Now the Audi RS7 brake disc is placed on the hub and perfectly centred by the centring ring.

Than the Porsche Cayenne 4-piston brake calliper is screwed tightly to the brake calliper adapter.

Now the Golf 5 R32 brake caliper carrier is mounted on the Epytec handbrake caliper adapter.

Here you can see how the handbrake caliper has to be mounted exactly on the steel axle. To mount the brake disc, the Porsche Cayenne and VW Golf 5 R handbrake caliper of course must be removed again.

Then the Epytec Tuning Adapter is mounted to the steel axle with the VW Golf 5R handbrake caliper.

Then the hand brake cable is connected to the small pump and the brake pads can be fitted.

Then you can reconnect the brake lines and bleed the brake completely. With this conversion, it is recommended that you convert directly to steel braided brake lines.

These have the following advantages:

No pressure loss when brakes are applied, noticeably precise pressure point
No swelling as with rubber lines
Cost savings, as steel braided lines have an almost unlimited service life and do not have to be replaced every 3-5 years.
Shorter braking distance
Protection against martens
Optics

Now you can mount the rim again.

Now you can mount the rim again. 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).

Now the conversion with the Porsche Cayenne and R32 handbrake calipers and RS7 356x22mm brake disc is almost complete.

Finally, the clearance of the new brake system has to be checked. To do this, turn the vehicle completely to the left and right and check that nothing is rubbing against anything or that nothing is touching anything, e.g. the suspension joint, wishbone, etc.

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).
