Donlock Posted January 18, 2020 Share Posted January 18, 2020 What do you use to clean lines out after setting for many years. I have new hoses and new wheel cyl and a kit for master cyl. Don Link to comment Share on other sites More sharing options...
3macboys Posted January 19, 2020 Share Posted January 19, 2020 I would strongly suggest replacing them - truthfully for the small cost it's not worth the risk of one failing and there is no way of knowing really how strong they are. They may look good on the outside but weak on the inside. Just my 2 cents. Don 1 Link to comment Share on other sites More sharing options...

DFeeney Posted January 19, 2020 Share Posted January 19, 2020 Hello Don, I also have early Plymouths with copper brake lines. I have been told that these lines are not regular copper but a tubing that the refrigeration industry use today. I have a old fashioned siphon gun that holds about a qt. and you hook up your air hose line to it. I would blow the line out first with air to make sure its open. If blocked use a length 10 ga single strand electrical wire to run into the line to unblock it. Then put brake fluid in the siphon gun and wash out the line. Since it's brake fluid any residue left over won't hurt anything. Make a device to catch the brake fluid coming out as it is harmful to paint and makes a general mess. Just a thought.

Thanks Don My 1932 Dodge Brothers DL sedan has the same type of brake lines as your Plymouth. Your brake cylinders accept modern fittings. I replaced all the brake lines on my car with double flared Cunifer copper-nickel tubing. It has a coppery appearance, is very easy to bend and has an very high pressure rating. Old copper lines tend to become brittle with use and vibration. Cunifer looks original and you will have a comfortable feeling of safety and peace of mind. 2 Link to comment Share on other sites More sharing options...
