Low Pressure Test
WARNING: This page is about a different car, the 2003 BMW Z8 and 2002 BMW Z8. However, it is still accessible from the selected car via links, so may be relevant.
- Apply brake pedal until pressure reading is 28-70 psi (2-5 kg/cm2 ). Vehicle and gauges MUST remain still to avoid producing incorrect readings. Pressure should remain constant for at least 5 minutes.
- If pressure drops considerably, check all rubber components in brake system for leakage. Test both brake circuits and record readings. Bleed brake system after completing test.
