Installation - Porsche 996 TT Repair Manual

3. To remove the hydraulic unit −D− , carry out the following removal
procedure:
Undo the brake lines on the hydraulic unit.
Remove the lines between the brake master cylinder intermediate piston circuit and the hydraulic
unit.
Close the brake lines and the brake line connections with suitable plugs.
Pull off pressure sensor plug.
Unlock/disconnect the control module plug on the hydraulic unit. Cover the plug connector and the plug!
Note
• In the case of assembly work on the hydraulic connections, the electrical plug connections on the
hydraulic unit must always be connected!
• This prevents the plug connections on the hydraulic unit or in the plugs inside from being splashed
with brake fluid or water!
• Any damp plug must be wiped dry before being disconnected from the plug on the hydraulic unit!
• Brake fluid on electrical contacts (even thinned brake fluid) leads to corrosion and may cause faults in
the system!
Undo and guide out the hydraulic unit. In the case of unfavourable tolerances, remove the hydraulic unit
without the bracket for the hydraulic unit.

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 => Bleeding brakes (vehicle with PSM).
