<center><img src="http://lobster.2limited.com/images/bbrakes/evoms/brake%20line%20issue.jpg"></center><p>I had just installed the Boxster caliper and SS lines to the A4 over the weekend. Everything was torqued down, lines flushed, checked - no leaks. After driving the car for about 100 miles, I noticed there was alot of little (oil like) spots on my fender. Tonight, I checked the wheel and wheel well, and everything is covered in brake fluid!!! There is even a little puddle under the wheel! F'ing Great! After taking the wheels of and checking the connection, it looks like the line connecting to the caliper has come loose! I assume the steering (right/left turns) have torqued the line loose, b/c I was able to easily tighten the lines again. I've contacted the vendor about this issue..., but wanted to know if anyone has come across/seen this issue before? BTW, the line only goes in as much as the picture shows.

Any suggestion would be greatly appreciated.

Thanks,
Cris

i don't thing this will ever stay tight.

wnut

scary. first time i've heard of this happening.

Cris

but they seem to be the same lines others are using for the boxster caliper - the other kind is the banjo connection type. Not sure if one is better than the other tho.

I'm tempted to put some loctite to prevent the line from coming loose again. argh!

the brake lines on my stoptechs have never come loose... no locktite either, hmm

Cris

or, do they use the banjo nut type. Just curious to know if I'm doing something wrong here.

Thanks,

I don't remember what mine look like at that junction - it's been a while since I looked at that side of the caliper, but here are some suggestions:

1. Wash the car ASAP, brake fluid eats paint.

2. There sure is a lot of thread protruding. Like I said, I don't remember if mine do this or not - but I think I would have been worried if they did, and I wasn't worried after my install. You should be able to eyeball into the caliper to get an idea how far the line is supposed to penetrate. This kind of connection is supposed to bottom out.

3. Try and get an idea if you have enough (or too much?) slack in the line. The amount of slack will vary based on suspension height, so it's not necessarily one-size-fits-all. Look at the lines at full steering lock in each direction, with the suspension fully loaded, and with the suspension at full expension (up on jack stands, maybe with the wheel on.)

4. Before using Loctite on any part of the braking system, I'd double-check to make sure it's appropriate for the application. For all I know, Loctite turns into super hi test frictionless grease at 1200 degrees?

5. Torque. Too much can be almost as damaging as too little on those fittings.

Mistakes can happen. You may simply have the wrong lines (wrong length, or wrong fitting.)

Good luck Cris,

Cris

It looks like we both have the same brake line - notice the extra threading. Apparently, the lines are correct and everything should work. I've emailed Paul W about this,... hopefully I'll get a reply back.

Good news!

you want the seat on the end of the fitting to do the sealing inside the caliper, not the nut shoulder doing the sealing on the caliper body.
