Bumping this thread. Has anyone tried this booster plunger seal repair kit?

URO Parts Repair Kit 001 430 0708 for ATE Brake Booster Plunger Seal 03.7718-5028.1

R/R video from youtube:

I have hissing under the dash when I press the brake and a hard brake pedal after its down about half way.
My '97 R129 SL500 has an ATE booster and master cylinder so I was thinking of giving this a try.

Hey brucemid, have you tried this URO part seal? I bought it but haven't installed it yet. Just wondering if it's possible to do it without taking brake booster out of the vehicle..

How did you do it?

Bran,
Unfortunately I could not get enough information to be confident it was a direct fit to my booster. I ended up replacing the booster with a new one I bought from AutohauzAZ. Sorry I can't be of help. I can't imagine doing this job however without removing the booster. Please re-post to the thread with your outcome and learning!

Bruce

I was able to get the seal from my local re-builder who rebuilds and sells to Auto zone and others.When I was buying the seal he laughed and said" you are wasting your time that seal goes from inside the booster.to change it you have to open it up"I said ill take the $30 gamble..well he was right..the seal is installed from inside the booster..i went back and purchased the booster from him.

Your local re-builder hasnt kept up with progress, or he's blow'n smoke up your....
Not sure what type of seal you purchased, but here is the DIY part that is required to resolve the brake hiss.

And no requirement to disassemble the BB; it's installed from the outside.

Hi Guys

I did the URO seal kit thing - worked a treat just be slow and patient
Hardest part was getting out the booster

Disappointed with URO seal kit

Say, I'd like to know if your seal is still holding up? I was very disappointed when replacing the split seal on my '03 ML350's brake booster with this URO kit. The difference in pliability between the factory seal (soft) and the URO seal (hard) was concerning but I went ahead and installed it. Even with plenty of silicone lube, the seal resisted seating and eventually the outer ribs separated like O-rings rather than conform. Now I have no confidence in the seal and will replace the entire booster prior to an upcoming road trip. Don't know if my URO seal was typical or perhaps just old and dried-up?

This is the seal you want. It will cost $35 US which includes shipping. Contact them to see how long it will take to arrive. Photo of what you will receive in the mail.

Understand that the booster must be removed to install the seal correctly. Use the Uro installation video but using this seal.

HI Yes still good

Real pain in the bot to get it in, had to get rubber grease and then try to help it in with a dull screwdriver pushing the lips in, even then did not get it all the way in.
If I were to do it again I would rig up a simple base to hold the booster and a lever over the top to press the tube down or maybe use a proper press gently. It is as if the new seal is just a little too big to fit easily. But it did work,

Now for the stalling on accelerating .................grrrrrr
