BlueDevil Posted September 26, 2023 Share Posted September 26, 2023 I ran into a problem when I started on my brakes. I assumed that all the cylinders had the same mounting bolt spread. You know what they say about assumption. Turns out the fronts have 1 3/4" spacing and the rears 1 15/16". So you need 2 of each. Also here is the 5/16 x 1/4 copper coated steel brake line I am going to try and use as it is safer and has basically the same appearance and it is under $20 for 25' 1 Link to comment Share on other sites More sharing options...
$um Fun Posted September 27, 2023 Share Posted September 27, 2023 Best thing you can do is get the wheel cylinders rebuilt and sleeved with stainless steel, they will last for years. I painted mine with cast blast to keep the rust away and so far its held up pretty well. 1 Link to comment Share on other sites More sharing options...
BlueDevil Posted October 19, 2023 Author Share Posted October 19, 2023 Stopped by White Post last week and talked to Billy. I have new rear cylinders but fronts are elusive so I may go the rebuild route. I am going to replace the brake lines with steel since the copper coated steel looks like the original and is safer in my opinion. I am also going to use a double flare vs the original single. I am concerned about sealing. Pic 1 is comparison of original copper and new copper/steel. I am not trying to duplicate this line on the right. Pic 2 is the end flares Pic 3 is the CalVan flaring tool Pic 4 is the tool assembled Pic 5 is the flare before final forming. I cleaned up the edges of the hole with a tapered reamer.

BlueDevil Posted October 21, 2023 Author Share Posted October 21, 2023 Here is the right rear brake line. The tubing is easily bent by hand. Link to comment Share on other sites More sharing options...
BlueDevil Posted October 21, 2023 Author Share Posted October 21, 2023 Does anyone know how this line is attached to the rear axle? Clips around the pumpkin? Straps around the tube? Nothing? Link to comment Share on other sites More sharing options...
leomara Posted October 21, 2023 Share Posted October 21, 2023 You may know this but if not Jay has a Model 75 coupe maybe he knows the answer. Link to comment Share on other sites More sharing options...
BlueDevil Posted October 21, 2023 Author Share Posted October 21, 2023 Based on the photo in the owners manual there appear to have clips at 10 and 2 o'clock on the pumpkin Link to comment Share on other sites More sharing options...

pre1939chrysler Posted October 23, 2023 Share Posted October 23, 2023 Yes Jay knows, but they ask everyone else. Bill, ask the person who will work for you. Just expect a lecture. ,advice is cheaper than parts. Know anyone who can locate a smoked mirror clock or any other part, I do. Link to comment Share on other sites More sharing options...
BlueDevil Posted October 25, 2023 Author Share Posted October 25, 2023 Ok, do I paint the 75 master cylinder black or cast iron? Link to comment Share on other sites More sharing options...
