Swapped my servo hose yesturday. As per the useful thread . The only difference being I made a pipe joiner to help pulling through the pipe. If anyone wants it to do theirs drop me a line.

Hi FLD, what useful post did you use? tried a search and read lots of the older posts, but can't spot a sticky/guide. Mine's started to fray at the entry to the servo up the front. Woke up quicky a couple of weeks ago when my brakes lost what felt like 99% efficiency on the fourth roundabout on the way to work. I'd been fitting a mesh flter to the cabin intake on the weekend, so must have dislodged it enough to jump off. I've cut an inch or so off the end and the condition of the pipe in the engine bay looks fine, but might attempt to swap it out if it's not toobig a job. By the way did you get a new hose from Vaux or replace with a generic? I know this should have been covered under a recall, but I was told nothing was outsanding when I rang Vaux customer care line last year.....then again when I asked where the nearest VX service franchise was they just referred me to local Vaux garage, so their info obviously is not that accurate. Even if its a free fix at Vaux, think I'd rather do it myself if possible. Thanks.

How long are the pipes and what diameter? I wouldn't mind a silicone one

[H1 HWK]

From Wolfstone's "what does this pipe do" post last year........"Part No. from Vauxhall is 93188760 and the description I have is 'Brake servo unit vacuum hose' and dimesions I've found state 10 x 18 x 3500mm. Cost from Vauxhall is about £38. " Looks like plenty of supply options on ebay For silicone for less than Vaux cost e.g. mrsilicone, also the outside diameter of the silicone stuff looks like it's 2mm thinner (10mm id x 16mm od), so potentially may be easier to thread through the VX's skeleton? Anyone know if the servo hose has to meet any specific temp/manufacturing specs before I order a length of shiny blue to match my europa?

Raising an old topic I know but were there any further developments with this? I'm thinking that the vacuum hose on mine is knackered, doesn't have a red line on it that I can see and is pretty cracked at one end. I'm just going to replace it as a matter of course. I am getting hard brake pedal at the top of the range and it's happening increasingly more and more. The slightly smaller od sounds appealing when threading it through the sill and then I can just add to the grommet to stop any vibration on the hose.

This is the tube;

And then the non-return valve I was going to use;

Then to over spec things, I was going to go for some form of hose clip to add support to the ends to help prevent the cracking/splaying that happens to the hose.

Does this sound correct?

Hi sford, In the end I just trimmed back the frayed end and refitted it. I got it double checked by Andy at QMech during a service and he said it looked fine so I haven't touched it since and all working well. If yours is just frayed at the end, maybe get the nonreturn valve and fit it up front by the servo so that it gives you an extra inch or so to trim off the damaged part?

[sford]

The bit that's cracked/fraying is at the rear so I prob have a little room for movement. Makes sense to try the cut and fit part first so I'll do that but the hose may be as old so might just be stalling the inevitable. Tom

Be wary or replacing it with generic silicone pipe. Many of those generic silicone pipes can't cope with serious vacuum and can collapse (especially when hot). I have had a few I've rejected for that reason just for the engine bay vac signal lines.

I bought a new vauxhall one (red stripe and all). It still splits on the ends! When I do it again I'll just buy vacuum rated hose from CBSonline. I'm a work-shy little moaner and even I think this is a fairly straight forward job. Pretty much along the lines of: 1) jack up, 2) main tray off 3) disconnect old hose from motor 4) join old hose to new hose 5) take off black inner sill piece 6) Pull through using access hole in sill 7) push/pull hose into front bonnet area. 8) disconnect join in hoses 9) Connect new hose to engine / servo. 10) Refit tray 11) let down off jack. 12) brew up. Takes about 30 min to 1 hour.

Cheers Nev. I've been looking and normal vac hose isn't that expensive either so will probably go with the right stuff for the job. I'm not as fussed over the form if the function is correct. Cheers FLD, that's what I was thinking too.

Anyone remember why vauxhall changed the original hose? I can't recall if mine has the red stripe

[sford]

I think it was a case of it fell to bits quickly, or so that's all I've found so far.

I spoke to vauxhall last year regarding my servo hose and they said it had been replaced (no recalls on your car). The hose didnt have the red stripe down it. I found that i could of got away with cutting the ends back and reinstalling.

However i found once removing the servo hose there where a number of soft areas along the lengh of the hose. For the sake of £40 ish and an hours labour i would replace the pipe. My theory was, how would i feel if i ran into the back of a fellow vx'er just because i was being a tight arse.

This is why they changed it:

Cheers guys, I'll take a look at mine tomorrow.

[vocky]

Mine was replaced at three years old under warranty and I replaced that one late last year as the replacement was over six years old.

That's scary!
