Pressure Adjustment (Quest)
- Ensure vehicle is in unladen condition. Have one person sit in driver's seat. To stabilize suspension deflection, have one person sit in rear of vehicle and then exit vehicle slowly.
- Attach a lever to LSPV stopper bolt. See Fig 1. Adjust spring length to about 6.0" (152.5 mm). Attach one pressure gauge to front brake bleeder and another pressure gauge to rear brake bleeder.
- Bleed air from front and rear bleeders. Depress brake pedal until front brake pressure reading is achieved. Check rear brake pressure. See DLSV PRESSURE SPECIFICATIONS table.
- Ensure rear brake pressure reading is as specified. See DLSV PRESSURE SPECIFICATIONS table. If pressure readings are not as specified, adjust spring bracket. See Fig 1. Repeat test. If pressure readings are still not as specified, replace DLSV and repeat test.
