Greetings everybody!! Cruzin' in to introduce myself & my latest project. '55 Mainline with the 223ci /3spd ******. Nothin fancy but it's all there.. Quick question... Has anybody here upgraded the brake master cylinder to a dual port type on this type of car? Lookin for info on this subject. Any input would be greatly appreciated. thanks , Sid
These are O'Reillys part numbers New MC 501320 Rebuilt Cardone 101488, the rebuilts are usually a Bendix casting which I like.You will need a 20" X 3/16" line to add, you will need some br*** fittings to hook up the lines,The parts monkeys usually are not much help, I found everything I needed at ACE Hardware you will need 2 adapter fittings from the master to the 3/16" lines,you will need a 3/16" "L" fitting to go from the existing front line to your new line connecting to the front port of the master,your existing 3 way block that had the lines running from it will retain the line running to the rear you will need an adapter to install the brake sending unit into the previous front line port.Do a real good bench bleed on the new master,check all the rubber lines front and rear for cracking and replace now if needed.Make sure you have a flare nut wrench and soak all the old fittings with PB Blaster as they can strip easy.You will feel the difference!Your old master used 4 bolts the new uses two when you mount the new master reinstall all the bolts as they support the pedal bracket,your existing brake pushrod shoud be OK.
Welcome to the group! Looks like Jeff's already got you pretty much straightened around the the popular master cylinder swap.
Welcome, if you need to replace the master cylinder. I just finished the same project and have not do***ented the entire master cylinder install due to a broken arm. You can go here to see my build http://1hot54.blogspot.com/
Hello, and welcome! I had the brakes upgraded on my '56 to power drums. Got the booster & m/c setup from Toms Cl***ics, about $200. Ron
I am a visual guy so here are some pictures describing what JeffB said up above. Sorry that the pictures are so dark. Here is the back brake line coming in and attaching to a T fitting that has the relocated brake light sensor. I added the brake light sensor to the rear line since the portioning valve will put pressure on the rear first. Here are the front brake lines coming in to a T connector. Here is a over view with the Master Cylinder
Thanks everybody for the warm welcomes and great info!! Haven't been able to respond lately cuz I'm out of town on business. Should be home this weekend..
