Leak Test Procedure
If an air leak is suspected, use of a proprietary leak detection spray GOTEC LDS (STC 1090), or equivalent, is recommended. If this spray is not available, a substitute spray must contain a corrosion inhibitor, and must not cause damage to paintwork, plastics, metals and plastic pipes. This procedure should also be used where pneumatic components have been disturbed.
- Ensure system is fully pressurized.
- Clean around area of suspected leak.
- Using manufacturer's instructions, spray around all component joints and air springs, working systematically until source of leak is found.
- If a component, e.g. air spring, air dryer is leaking, rectify by fitting a new component.
- If an air pipe connection is leaking, cut 5 mm off end of pipe. Fit new collet. See AIR PIPE CONNECTION COLLET & "O" RINGS under REMOVAL & INSTALLATION.
- Reinflate system, carry out leak test.
