Braking performance test - Data for compulsory vehicle testing as per 29 StVZO (German Road Traffic Regulations)

Information

The specified braking force contribution values relate only to the braking performance test as per 29 StVZO (German Road traffic Regulations)
Values valid for grey cast iron and PCCB brakes.
The specifications for 997 vehicles also apply to 997 Turbo and 997G vehicles.
The specifications for 970 vehicles also apply to 970H vehicles.
The specifications for 92A vehicles also apply to 92AH vehicles.
The specifications always apply to all models of the vehicle types specified in this document.

⁽¹⁾	The pedal pressures relate to the recognised maximum permitted gross weights (maximum value/model line) and are valid for total braking of at least 58%

⁽²⁾	A sufficient vacuum supply must be assured for the assessment of the rear-axle braking force contribution. The reference values for the assessment must be between the specified value pairs.

⁽³⁾	The minimum rear-axle braking force contribution ø relates to the front-axle load distribution/model line. The minimum front-axle braking force contribution (1-ø) relates to the rear-axle load distribution/model line.
