Marzocchi Posted November 5, 2008 Report Share Posted November 5, 2008 Hi,Brake line junction leak are frequent with our cars. I have read some posts about it not being serviceable and needs to be replaced. This summer, mine started to leak at the bottom where the big fitting is threaded into the junction body. I bought a used one for 10$ and it's fine. I decided to dismantle the leaky one and discovered some interesting stuff.The big fitting can be removed quite easily and I don't see why it can't be resealed. At the other end of the junction, there is another fitting that can be removed. After removing it, I found a screw that looks like an adjuster. If I understand correctly the function of this part, it uses springs to divide flow to front and rear brakes. Would there be any benefits to adjust brake bias on our cars?Sedan and wagon use different part number for this part but are identical. Maybe they came with a different brake bias adjustment from the factory? Link to comment Share on other sites More sharing options...

Marzocchi Posted November 6, 2008 Author Report Share Posted November 6, 2008 The larger fitting has a ring where it touches the part. This is where mine leaked. I've read that this is not serviceable but it just need a new seal.At the other end, the smaller fitting, hides a screw. It looks like a fuel mixture screw on a carb and can be turned. I don't know if this screw modify preload on the springs that are inside the junction. Link to comment Share on other sites More sharing options...
