I have a question! what is the reason for two different size line's coming off of the master cylinder (3/16"&1/4") to the distribution block?

 

The 1/4" is for the rear, 3/16 for the front.

 

I know where they go, but why different size's?

 

The different size lines started in 1967 with the dual circuit M/C, presumably to preclude incorrect installation on the assembly line.

 

now that makes sense! I am surprised some one would know that!

 

Joe P. Is smarter than anyone who ever worked / toiled in Flint, Michigan.....

 

you would think that he would have been at least an Engineer. I worked at Jeep as a Tool and Die maker for 41 years and I never picked up on that!

 

Joe P. Is an Engineer and Much More....
and went to M.I.T. --- the premier university on the planet for those studies / sciences /
businesses/ etc., etc. ( P.S. --- and LOVES Cars, particularly OLDSMOBILEs !!! )
Craig.....

 

it is always nice to have some one around that is more knowledgeable than your self and more than likely one of the reasons I joined this site! I kind of wish I knew everything but I do not, but it is fun to learn something every day, especially working on this Oldsmobile!

 

well I got my bracket made for the distribution block, and now on to making the new brake lines!
