I posted my problem in DIY section but got no answer I've done m5 brake upgrade and have installed stoptech SS lines. Today I removed the wheels and noticed a hanging drop of fluid by the area where lines connect. I retightened them again but connection seems pretty snug . These lines come with two flat w but I do not see the use of them. Any idea where those washers go. Stock lines seam to have lips to prevent from rotating but stoptech ones don't. I am just concerned how safe are they?. I cleaned the area and will recheck it again for leak but any advice from those who have them on there car?
Thx

 

I checked them and they leak all for corners. Now I am definitely convinced myself that there are no aftermarket parts for BMWs that have no problem, was thinking to do KW coil overs but no way.
I need to go to 4 hour drive tomorrow and need this fixed as soon as possible. i see lot of you have SS lines on your cars.please tell me how i can stop them from leaking. i am thinking to fo to dealership and swep them back to OEM lines.

 

Also one side of front brake pad is not completely toughing the rotor. Do you think they will mate by the miles or pad are not sitting properly?
