Rear air bags removed

Roger 47 · Jan 27, 2012

Hi All
Eventually got the blighters off. But I noticed that although the air pipe released ok there are some score marks on the end where it pushes into the coupling. I don't want to chance having an air leak.
What I would like to know is it alright to put a new lenght of pipe in using a inline connector. I've seen the 6mm pipe on ebay with the connectors.

Thanks for any advice

Unnecessary I would say. Get a tube cutter or even a stanley knife if you've a steady hand a cut a few mm off the end. There should be enough slack in the pipe to allow you that much. The important thing is to cut as nearly perpendicular to the pipe as you can as this is what will seal against the o'ring inside the little brass collet. In fact it would be a better investment to replace all the rubber o'rings as these can get deformed over time and then seal less efficiently.

Check the pipe very carefully before you do this. On my pipes there is a slight bulge a few mm from the end. I don't know why it's there, or even if it's meant to be, but it seems enough to stop it entering the bag fitting.

The bulge is intentional, it's there to aid fitting the pipe, you grip the pipe with the special tool and push against the bulge when inserting the pipe into the airbag, valve block etc.

Obviously if too much is cut off the end of the pipe the bulge will stop the pipe going in fully

I suspect the score marks are from pushing the pipe into/removing from the connections, wipe clean the end of the pipe and then place a drop of washing up liquid on the end of the pipe as a lubricant.

Push fully home the pipe, pressurise the system and check for bubbles.

Tip. I have used a sharp pencil sharpener to make a slight taper on the end of the pipe, before now...

Thanks for all the comments, finally fitted new ones today and all went well. The problem pipe went in ok and the bulge in the pipe just rests against the release collett. I've tested both pipe unions with soapy water and no bubbles, thank god.
Now on to fitting new discs and pads all round.
