Vacuum Line Brake Booster - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Viper5 · 04-13-2009, 08:56 AM

I dropped my vehicle off at the dealership. It's a 2000 Boxster S. They said I have a leak in my vacuum line brake booster. Is this difficult to replace? They are asking for around $500. Thanks.

Actually pretty easy DIY but you will have to remove the master cylinder and brake lines, then bleed the system after (if your fluid is 2+ yrs., you're due anyway).

Aside from the normal wrenches and sockets, you will need a T-45 Torx (suggest a socket so you can properly torque it when through - 17 ft. lbs.).

IIRC, the part runs $250 + brake fluid ($20). PM me with an email and I can send you the procedure as a word doc. Then decide.

I tried sending you a PM but it says you have too many already. I will check my PM periodically if you want to send it there. When you start talking about master cylinder, is that difficult? It sounds intimidating. I only have tools, nothing fancy. I'll have to pick up that one torx you mentioned, but is that really all that is needed.

Which part are you saying costs $250? The T-45 only costs about 5 bucks. Email is airplaneking@hotmail.com

Sorry, mailbox cleared. I need an email because you cannot make attachments to PMs.

My email is posted above.

Thanks for the file, however I think there has been a miscommunication. I just need to replace the vacuum line (part# 98635557507) since it has a leak in it. This line goes to the brake booster but the brake booster itself is ok.

This is the piece I'm trying to move:

That's the vacuum line and it's just a press fit into the rubber grommet on the booster. You may have to rotate it while pulling it out.

I'm having an extremely difficult time with this piece. When I try to rotate the hose, it will only go a few mm. I'm also worried I'm going to break the part connected to the engine if I pull too hard.

On the engine side, there is a spring clip, somewhat shaped like a isosceles trapezoid, that secures both the power steering hose and the brake booster vac hose. Lift this up and then the vac hose should pull off. Take care not to lossen the pwr. steering hose or you'll lose the PS fluid.

Viper5 · 04-17-2009, 08:10 AM

I don't see any such trapezoid. All I am able to view is exactly what the picture shows. I have an aftermarket top which will only go up a tad giving me little room to work with. I do, however, see two screws that connect the hose to the engine casing. Is it ok to remove those so I can pull the part off the engine?
