When I remove the vacuum hose from the brake booster to replace it, do I need to do anything to "re-pressurize" the system? Or is it a "closed" system until the engine is started and the brake pedal is depressed?
For all of the hair pulling on my end, the yellow connector piece was very easy to remove. I had read on another forum to use a wood screw to "gently" grip into the yellow piece, then use the wood screw and lubricant to work it out. Used a 3/8 x 3" wood screw from Home Depot. Worked like a charm. Did not even need the lubricant. I pulled just a little to see if I had gotten a grip on the piece with the threads of the screw it is slipped right out.
The cap with the two tabs that I shattered into a million pieces (before I knew what I was doing) just popped back on the remaining cage piece with just a little push and a click.
The guys a mymercedesparts.com were awesome. I was concerned that the hose was just the hose and not the connector. Confirmed that hose did have the connector and they also helped me figure out that I only needed the cap and not the cage and the o-ring. Saved me $6 in parts. Really cool of them.
The DIY for this has been posted to the R170 DIY thread. If you guys notice any issues that need correction or clarification, just let me know. I will correct the document and re-post. Thanks again to all those that helped me get the info I needed to get the job done.
