65 Brake lines

[Murray S.]

When did the switch occur from 3/16 to 1/4 inch brake lines? I want to change my brake lines back to steel lines in preparation for National Judging. My serial number is 3124.

Murray,
I believe all 65 brake lines were 3/16" and all master cylinder fittings were 3/16" with no adaptors.

No, not true, The drum brake cars (around 300 or so) do have a 1/4" line from the master cylinder to the brass block at the left front corner of the frame.

Has your car been judge Regionally? If so what were the results regarding the brake lines? Some one will correct me if I'm wrong but believe to be judged Nationally one has to go through Regional Judging.

Michael -

Although that's an excellent idea, it's not a requirement - the only prerequisite for National judging is a Third Flight or higher award, under the same owner, within the three years preceding the National Convention. Probably not a great idea to go to the National without going through Regional judging first, to avoid disappointment.

Thanks Gene,
I did not know that. Do those have a bushing in the MC from 3/16 to 1/4?

John -

J-61 (drum brakes) used a different master cylinder, which had a residual pressure valve in it - the part number for the J-61 master cylinder and the 1/4" front line are shown in the J-61 Section in the Assembly Manual.
