Hello everyone, wanted to show this video where I replace the leaking plunger seal of the Brake Booster without removing the Booster from the car. It can be done with the seal from URO (see comments section for link). The video was done on a Volvo, which uses the same ATE Booster as several Mercedes models from around 2000-2012. Hope it helps everyone with this issue

Great video Oragex, very detailed and informative!

For the record, Oragex received no compensation from URO for making this video, and had no contact with us prior to posting it.

uro is junk from china

Everyone is absolutely entitled to their opinion, and we respect that.

Some folks might not realize it, but in today's global economy more and more Genuine and OEM parts are now made in China and Southeast Asia. Many URO parts are manufactured in these same factories, and the only difference is the boxing at the end of the production line. If someone doesn't mind paying more for an item that's still made in Germany, it's good to have that option. For someone on a budget, it's nice to have less costly options, especially if all brands available are coming from the same factory in Asia anyway. In that situation, price and warranty become more important than the logo on the box, and URO's two year warranty (and lifetime warranty on URO Premium items) beats many of our competitors. And we're in Southern California, so we're easy to contact if anyone ever needs assistance.

Regarding the hissing brake booster issue, the original factory seal isn't made of anything special and it only lasts a few years. Most people would rather replace a $30 seal than a $500+ booster every so often, especially if they can do it without having to remove the booster from the car. We don't suggest that method due to the technical difficulty, but give kudos to Oragex for showing how it's done, so adventurous DIY enthusiasts and technicians know what to expect.

I had the Uro seal in my hands, and it was the exact replica of the genuine ATE seal I pulled from the brake booster. Fitting was also perfect and tight. The other option is a red seal unbranded, of which I've read about an owner that he had a very hard time fitting it. These are the two options available. Otherwise it will take a complete new booster from ATE but more importantly, it will need removed from the car. Especially on the right hand driving cars, this may be a difficult task. So the seal route is not only the easier one - as long as one manages to replace it which is not very obvious - but also a much cheaper one, even for DIY. Again, just my opinion, at the end of the day everyone is making their own choice. Cheers

oragex thanks for both information and the link to you tube video .
And also for the explanation of parts made in China and Germany from IRO rep .

Its true about where lots of these mb spare parts come from .

Uro: It takes a long time to overcome a negative first impression; sometimes it is simply not possible.
