My Burstner Delphin is on a 2006 Renault Master base vehicle. The wing mirrors are supposed to fold back on impact but are virtually immovable, in fact I have applied a fair bit of pressure but cannot shift them backwards.


Is there any way to loosen them off a bit? I reckon that they will cause some damage to the door in a collision because they are virtually solid.


Any help appreciated thanks.

My Knaus is on a 2007 Renault Master chassis and I wasnt sure they would cold back. I checked with this site and was told to give them a good push. I did and it was fine. Two hands , stand behind and give a good push but hold on to them.

Not sure if you can loosen beforehand.

Thanks Andrew. It seems a bit strange though doesn't it as all other manufacturers design them to move with little effort. I can only hope that I don't come into contact with another Renault as the result could be disastrous.

When I had my Master I thought the mirrors never folded back as pushing on them appeared to have no effect. One day I drifted close to a hedge at low speed and when the mirror struck the hedge it folded back. I opened and folded it a few times and it took a lot less effort to fold it. I was a bit more brutal on the other one and this freed up after a few open and folding operations.

Thanks Ray, I might need to be a bit more brutal to move them but I did not want to do that in case I damaged something. If I can get them moving I might try a drop of 3 in 1 oil on the pivot points. They have probably never ever been folded back from new.

I have a suspicion that the stiffness of Renault Master wing-mirrors may be linked to the weather. In summer it has been somewhat easier to push ours back than it is in winter when it's cold and very wet.
I have tried various dispersants and lubricants (WD40, easing oil and plastic hinge lubricant) with varying success. I couldn't really say which one actually made them easier to move. This 'problem' is nothing in comparison with the wing-mirrors on our old Auto-Sleeper on a VW chassis, which could fold back in a strong wind!

Thanks, that is quite interesting to hear.


I have been out and got them moving now but they are still both a tad stiff. They have both been liberally treated with Rocol penetrating spray as well, so I will give them an hour or two and see if there is any difference.

The other day I tried to fold back the driver's side wing mirror and I couldn't budge it. I tried Bike Hut dry lubricant for push bikes. It worked very quickly.

Pedant alert

They are not wing mirrors (when did you last see those ) they are door mirrors.

Wing mirror


Door mirror



I'll get me coat

Isn't it amazing? I wanted to find out if the mirrors on our Knuas Renault based cab should fold or not so I did Google search and good old Facts came up with the answer.
