Scirocco & Quantum
- Regulator is located on right rear frame on Quantum, and left rear frame on Scirocco. With vehicle empty and fuel tank full, load driver's seat to 165 lbs. Bounce car several times, and allow vehicle to settle normally.
- Measure distance from top of tire rim to lower edge of fender lip (both sides). Attach spring tensioners to hold vehicle in settled position. See Fig 1 .
- Raise and support vehicle. Check measurement, and adjust tension if required. Using 2 1500 psi gauges, connect one to left front caliper, and other to right rear wheel cylinder. Bleed gauges.
- Pump pedal several times. Depress brake pedal until front gauge reads indicated pressure for first reading in BRAKE PRESSURE CHART. Record rear gauge reading. Increase pedal pressure until front gauge reads indicated pressure for second reading. Record rear gauge reading.
- If both pressures were high on rear wheel, loosen regulator clamp bolt, and reduce spring tension. Increase spring tension if pressures were too low. Replace pressure regulator if spring adjustment does not correct pressures.
NOTE:
DO NOT adjust spring tension with brake pedal depressed.
