Cobb SS Brake Lines (05/29/04)

One of the most important modifications before any track event or serious driving is the addition of stainless steel brake lines.  The stainless braided lines replace the factory rubber lines and will not expand with heat as the stock ones do.  This means significantly less brake fade and a consistent pedal feel.  In addition to the lines, I added Speedbleeders to make bleeding easy, and changed the fluid to Motul 600.

The installation is very straightforward.  Put the car on jackstands and remove all four wheels.  Flare wrenches will make the job of removing the stock lines much easier.  Start by spraying the nut where the hard line changes to rubber with some PB Spray.  With a pan underneath, loosen the nut and remove the rubber line.  Cap off the hard line with one of the rubber caps that come with speedbleeders.  Then remove the bolt that holds the rubber line to the strut.

Lastly, remove the rubber line from the back of the caliper.  This is a good time to replace the factory bleeder screws with speedbleeders.  There are two bleeders for each caliper (total of eight).  This will allow one person bleeding.

Here you can see the new stainless steel line in place.  Installation is simply the reverse of the removal process.  Be sure both washers are on the banjo bolt at the back of the caliper.

With the fronts done, move to the back end.  It is basically the exact same process, except that the line is held to the strut by a clip instead of a bolt.

Here is the completed rear brake setup.  Once all four corners are done, you'll have to bleed the brakes.

This is the brake bleeding procedure.  I used Motul 600 fluid to replace the stock stuff.  It has a significantly higher boiling point.
