Installation

Installation
1. Install in reverse order.

Note:
^ First connect the electrical plug connections on the hydraulic unit, so that the plug connections inside or on the hydraulic unit can not be splashed with brake fluid or water!
^ After bleeding, check the assignment of the brake lines/solenoid valves to the correct brake calipers! To do so, call up the PSM system with the PST 2 and carry out a swap test!

2. Bleed the brakes.

Note:
^ First bleed brakes as usual!
^ Do not carry out booster pump activation with the Porsche System Tester 2 until after this has been done (after conventional bleeding) as otherwise damage to the booster pump can occur!
^ To bleed at front on right with running booster pump, the bleeding device should remain connected (switched on)! Bleeding pressure approximately 2.0 bar!

3. When replacing the hydraulic unit, code the control module (manual transmission/Tiptronic).
4. Carry out the following tests:
- Check the system (brake lines and connections) for leaks.
- Read out and erase the fault memory of the PSM control module with the Porsche System Tester 2 (PST 2). Additionally perform the static test in the PSM system.
- Check electrical and hydraulic lines (brake lines) for incorrect assignment using the PST 2.
- Then start the engine. The PSM-related lights in the instrument cluster must go out when the engine is running.
- Carry out a function check of the brakes. Then perform a short test drive and perform at least one ABS control operation, taking the road conditions into consideration. Read out the PSM fault memory again. There must not be any stored faults.
