New Dunlop wheel brake cilinders
Re: New Dunlop wheel brake cilinders
congratulation Huib. seems to be a good techn. Design / Solution.
Thats the reason why the second serie´s brake ( sealing solution etc.)
is in general better than the first series one
But what is with the release of this part´s. I suppose it is the risk
of the owner to use this brake´s on the street.
Don´t want make it bad. Only the buyer´s need to know it.
To point it out, I don´t have any doubt that it work´s.
best regards
Andreas

Re: New Dunlop wheel brake cilinders
You have a good point about the legal angle. Your remark is also true for most if not all parts used on our Lancia's. The parts are either over 35 years old, thus out of warranty, or repro, often of questionable quality. To stick to the brakes, I already bought revision sets for original Dunlop cilinders that had seals made of rubber that is not brake fluid resistant (!). Those seals shrink within half a year, resulting in loss of brake fluid. Not a small leak which still takes you home if you top up the container regularly, but a massive leak like opening the bleed nipple. Also sleeving, which many do, has its risks.
There are lawyers among Fulvisti, who read this forum. Hereby I ask them to participate in this discussion and even suggest a notice I can put on the page of the wheel brake cilinders.
I have the cilinders on my car for a year and a half. They have done 75.000 km. They are also on some other cars but with considerably less mileage.
Another point is that hardly any one tests his brakes with only one circuit functioning. It can happen that one drives over a piece of steel wire which wraps around the wheel and cuts through the brake hose. Or if one happens to have the bad seals mentioned above on original Dunlop cilinders at the front, the front circuit will fail.
With the original Dunlop cilinders the retraction is already much when new. After many years of use the retraction has increased. As a result the 18mm master brake cilinder cannot supply enough fluid to the rear brakes if the front circuit fails. It has happened to me twice that front brakes (not of any of my cars) lost the fluid leaving me without brakes at all. Fortunately I am still alive and the cars were not wrecked. It is nevertheless an unpleasant experience.
The retraction of these new wheel brake cilinders is minimal and gives a better guarantee that the other circuit will still work if one circuit looses its fluid. The master cilinder has to be good with no wear on the cilinder wall at the start of the stroke. The margin is small with the 18mm master cilinder.

Re: New Dunlop wheel brake cilinders
As i said, i have no doubt that it works but there no approval.
If you use for example headlamps without the approval marks you
will not get a release from the german TÜV. And this is not a question of safety as brakes.
There was some years ago a long story about this items in the german "Oldtimer Markt".
( stainless steel was used for a solution ... I believe you know what i mean )
Difficult, but sometimes we have to go this way to keep our cars running.

Re: New Dunlop wheel brake cilinders
I agree with you, Andreas.
The bottom line is that we take quite a bit of responsibility. I take that seriously for my own cars and for customer's cars. It is a good idea to discuss that on the forum.
