I am new member here, but have been reading posts since joining and have noticed how helpful people can be and I need help. The brake line into the bottom of one of my calipers has a very slight leak - so the obvious solution would be to slightly tighten the line. Unfortunately the red painted calipers and line seem to have thick enough paint that a standard metric or SAE wrench will not fit, unless I remove the paint, which I don't want to do. What have people used to adjust this brake line nut?

 

I beleive you need an AN wrench.

 

What is an AN wrench?

 

It is a special wrench for those types of fittings. They are not metric or standard. They have their own sizes. Do a google search on AN fittings.

 

This brake line leak must be extremely minor. How did you come across it?? On my turbo, seems like the grit on inside of my front left rim is a bit, but only slightly more oily, than on right inside rim. Wonder if that could be such a slight leak of brake fluid is why I am wondering how you finally noticed the leak. Is it something that showed up on the pavement after parking??

 

This is a very minor leak. I noticed it while the car was elevated on my lift while upgrading to a Europipe exhaust. It was just on the inside of the wheel in one small area.

 

So when you say inside of wheel, that is surface where bolt holes are? So the brake fluid never made it to the flat circular surface that one usually washes when the wheel is washed? It is that large flat circular surface (6-7 inches wide) that you have to reach in thru the spokes with a brush to wash.`` I guess if that small. brake fluid level would not change. Also if you wiped your finger thru it , I guess it would have that smell of brake fluid.

 

I do mean the large circular surface, not where the bolt holes are. I don't have to smell the brake fluid, I can slight evidence of it on the brake line, before it collects on the circular surface (the accumulation was small).
