BR00.45-Z-1002-03A	Leak detection spray

In the event of damage to compressed-air terminals (1a) and pressure lines (4) a compressed-air connector (3) or a repair screwed connection (1) can be mounted.

Ensure that the repair is carried out carefully in order to avoid further leaks.

1. Remove compressed-air terminal (1a) from affected component (e.g. suspension strut) and cut pressure line (4) to suitable length using the knife.

Special care must be taken to ensure that the cut is exactly at a right angle to the pressure line (4).

2. Insert the truncated pressure line (4) up to the stop or 19.5 mm into the pressure line connector (3).

3. Cut the repair line (2) so as to obtain the original length and shape (straight end or 90° arc) of the line.

Do not kink the repair line (2). When cutting off the repair line (2) take into account the insertion depths in the repair screwed connection (1) and pressure line connector (3). Repair lines (2) supplied from through the spare parts channels, each repair (2), with one straight and one bent end.

4. Insert the repair line (2) up to the stop or to a depth of 19.5 mm in the pressure line connector (3).
5. Screw the repair bolted connection (1) into the component in question.
6. Pull plastic guard (1c) out of repair connection (1).
7. Insert the repair line (2) into the repair bolted connection (1) up to the stop or to a depth of 19.5 mm.

If necessary mark the repair line (2) at 19.5 mm with a felt-tip pen beforehand.

After insertion the pull back the pressure line (4) slightly so that the circumferential retaining edges inside the clamping ring (1b) engage in the outer surface of the line.

When pulling in or routing the pressure line (4) make sure that the pressure line (4) cannot be twisted once fastened. The pressure line connectors (3) should be attached with cable ties at a suitable point on the vehicle so that chafing of the pressure line (4) or noise are prevented

If bubbles form at the repair point after a leak test with leak detector spray, it must be checked whether the pressure line (4) is inserted as far as the stop. If bubbles continue to form nevertheless, then the pressure line connector (3) may be defective and a new pressure line connector (3) or a new repair bolted connection (1) should be used.
