WPT0 - Checking Brake Disc on the Right of the Front Axle and Replacing it if Necessary
(Workshop Campaign)
Model Line:

Taycan (Y1A / Y1B / Y1C)

Model Year:

2024

Equipment:

Front disc brake, with integrated brake carrier (M-No. 1LR / 1LS)

Concerns:

Brake disc on front axle, right

Cause:

There is a possibility that brake discs installed on the right of the front axle on the affected
vehicles do not meet the required specifications.
Due to reduced brake cooling, this can lead to increased brake heating and consequently to brake
rubbing. The occurrence of brake noise cannot be ruled out either.

Action:

Check brake disc on the right of the front axle and replace it if necessary.

Affected
Vehicles:

Only vehicles assigned to the campaign (see also PCSS Vehicle Information).

Required parts and materials
Information
Please note that the predicted failure rate is only 10%. The required parts must therefore only be ordered
in the event of a fault.
The part numbers of the required parts for the respective vehicle can be seen in the assigned scope.
For an overview of the campaign scopes, see:  Technical Information 'Warranty processing'
For materials (lubricants) required for carrying out the action, see the corresponding Workshop Manual in
PCSS. These lubricants are usually available in the Porsche Center.
