Brake Line Replacement for right front on 1970 Boss 302
« on: June 03, 2013, 03:55:08 pm »
Has anyone been able to replace the one piece right front brake line that routes from the Pressure Differential and Pressure Control Valve assembly on the left hand fender apron along the dash panel and through the hole in the right hand spring tower to the connection with the brake hose on the frame rail without removing the right hand upper suspension arm and spring?  The engine is in the car.  My initial attempts at positioning the new brake line have not been successful and I think I need to remove the spring and upper arm to allow routing of the brake line through the hole in the spring tower to its proper location.  Any helpful advise will be appreciated.

Unfortunately it's easier with the engine out. I don't recall any issues with suspension it the way. You must be feeding the line in from the outside?  I fed mine in from inside the engine bay bracing not installed.

I did this back in January with the engine out and bracing out also.  You will want the clearance to gain complete access to the proportioning valve to get that fitting tight and leak free.  You will need to replace the grommet at the apron.

Oh, and while you are at it, go ahead and detail that engine bay  ;D

Ah yes, I am an expert at scope growth.

+1 on the engine being out. Did this a few months back on my 70 B2 and it was a piece of cake. A while back I did it on my Mach 1 with the engine in place before I started the resto and it was doable, but a total PITA.

Thanks for the info guys.  I think I'll install a 2 piece line to get a functional brake system until I can plan to remove the engine at a future date and do a proper job of installing the one piece production level part at that time.
