Brake Servo Vacuum Hose (Part 2)

[Bowton Lad]

As previously posted in part 1 of ''Brake Servo Vacuum Hose'' I need to replace the 8'' (approx) hose that runs from the n/s inlet maniflod up to the non-return valve. The hose appeared to be held in place by a Jubilee clip at each end. Simple to remove I thought, naively. Herr Volkswagen has made things difficult as usual.

The top end of the pipe was easily disconnected by loosening the Jubilee clip & pulling the hose off the non-return valve. I loosened the Jubilee clip at the bottom end & slid it back to reveal a circular metal ferrel holding the hose onto the oulet pipe on the inlet manifold. Has anyone ever managed to cut/grind one of these ferrels off an alloy pipe without causing damage to the pipe other parts?

I have a 4.5'' angle grinder but that is a bit heavy duty for this job. I also have a Dremel but that may be too feeble for this job. Any ideas, please?

Dremel with the right bit would be my suggestion. If its alloy then any sort of grinding tool should eat it up no probs.

It's a steel ferrel clamping a rubber/cloth braided hose onto an alloy pipe which is an integral part of the n/s inlet manifold. The ferrel is smooth all the way round with no obvious sign of a joint. It is not like the usual crimp that VW used on such things as fuel hoses.

My worry is that if/when I try to grind through the steel ferrel I will accidentally damage the alloy pipe that the hose is attached to. The Dremel attachments I have all seem a bit lightweight for this sort of job. Is there one that I can buy that maybe up to the job?

A picture is worth a thousand words.
