There is no need to change the line size to the rear if you are sticking with the stock rear brakes. GM used the 3/16 line until the mid 60s. My 1965 C10 has the same size line.

wk2hons | Yes, I would. I've had several cars of 60's and 70's and the main brake line going to the rear to the rear axle was 1/4" on all of them. |

You can buy flaring tool sets to double flare the tubing.

Tony Dinh | I looked up a YouTube and he was doing a 66 impala disc conversion. He ended up converting his 7/16 -20 used a union to convert it into a 9/16-18 to connect the rear into the prop valve. His line was 1/4 tho. Do I need to convert my rear brake lines to 1/4? Because my current rear brake lines are 3/16 |

I’m confused on how the brake lines go in. The new proportioning valve is different from the original. Do I have to run all new brake lines? The proportional valve on the driver side looks like it has one inlet for the driver side front brakes and another inlet for passenger side where there in another proportion valve for the passenger side front brake then it leads to the back brakes. Then the diver side has an outlet of the master cylinder. On the new proportion valve it has two fronts and one rear inlet. And the rear inlet is a really big inlet that doesn’t fit any of the original brake hard lines. |

You can buy brake line from NAPA in 9", 12", 18", 24", and 36" inch lengths. It has to be double flared with a flaring tool after you put the fitting on the line. Big Dave |

jayoldschool | Yes, go ahead and bend the lines carefully. However, if the gap is too big you have two solutions. Move the prop valve lower with longer lines FROM the master, or, use a union with a short section of pre-flared line to connect the original line to the prop valve. You can get unions (threaded couplers) and pre-flared lines from any parts store. Or, flare yourself for a custom fit. Note that I am NOT talking about COMPRESSION FITTINGS! Never use on a brake system. |

68WASAGOODYEAR | Don't be afraid to bend them. I don't know if extensions are made, but if they are they are an additional leak point. |

Extending brake lines Doing a disc brake conversion; wondering how to extend the brake lines because the proportioning valve is higher up than the original. How do i get the brake lines up there. |
