Low-Pressure Test
WARNING: This page is about a different variant/trim than selected.
NOTE:
Perform test on both brake circuits, front and rear.
- Unscrew vent plug, connect pressure tester and vent. See Fig 1.
- Load brake pedal with a force of 30-72 PSI (2-5 bar), and block pedal with pedal support. Car and measuring equipment must remain perfectly still as vibrations will distort the result.
- Pressure should remain constant during five minute test.
- Check all rubber parts in case of excessive pressure drop.
- Bleed brake calipers and wheel brake cylinders after finishing test.
