40plymouthman Posted November 14, 2018 Report Share Posted November 14, 2018 I'm finally doing the disc brake conversion on my '40 Plymouth. Any body try using the ECI brake conversion kit? Quote Link to comment Share on other sites More sharing options...
belvedere666 Posted November 15, 2018 Report Share Posted November 15, 2018 I installed it on my 50. The brake kit was super easy. It bolts on with no modifications. But you cannot use your stock wheels. You need a 15 inch wheel or larger, with enough clearance. I am using aftermarket smoothie wheels with the original backspace. They cleared just fine. If you were going the route with their master cylinder kit, I suggest you look elsewhere. My master cylinder kit has been kind of a nightmare. Of course, I expected it to need some sort of adjustment to fit my application, but it’s just a weird combination of things that didn’t go together smoothly. I finally got it working as it should. But I haven’t taken the car on the road yet. Quote Link to comment Share on other sites More sharing options...

No. My car had 15 inch wheels. But the way the stock wheel centers are welded to the outer ring, the ECI calipers won’t fit. So, if you are running an aftermarket wheel, they have to be at least 15 inch. A 14 inch aftermarket wheel won’t have enough room for the big calipers that they use.

clarkede Posted November 15, 2018 Report Share Posted November 15, 2018 I have a 48 Plymouth and I'm interested in doing this. I see that there are several places to get these kits from. Some require proprietary calipers and pads,while others sell the brackets and you get the calipers and pads from an auto parts store. What do you guys think about Scarebird? https://scarebird.com/index.php?route=product/category&path=64 Quote Link to comment Share on other sites More sharing options...

Dennis Detweiler Posted November 15, 2018 Report Share Posted November 15, 2018 I installed a Scarebird brake kit on my 39 Plymouth. Bolted on with no problems. However, my car already had 15 inch wheels on it with radial tires. The spindles are one inch wider spacing. My rear end is stock, but already had wheel adapters. My next and final project is to install a dual master kit from from Wilwood 260-7563 which has remote reservoirs, 1 inch bore and line connections on the bottom of the master. I'm looking at Scarebird master adapter which looks like I'll be able to drill and mount to the original master mount. This master adapter is made to mount the Wilwood master. I should be able to keep the original brake pedal. Quote Link to comment Share on other sites More sharing options...

Hi, do you have pictures of the installation of your master cylinder, cause I am having difficulties with the rest of my installation, disc brakes and calipers ok.

Popmab Posted December 30, 2018 Report Share Posted December 30, 2018 (edited) did you see my pictures I uploaded? The master cylinder is totally different than the one I was sent and we cant figure how to modify it to work, a friend came into this site and found pictures of a modification and installation of this type of master cylinder and I am looking for finished installations. My car is a 1941 4dr desoto custom S8 standard transmission. Edited December 30, 2018 by Popmab more information Quote Link to comment Share on other sites More sharing options...

My car is a 1941 4dr desoto custom S8 standard transmission. The master cylinder they sent you is a late 60s early 70s mustang master cylinder. It has two reservoirs. One for the drum brakes in the rear and one for the disk in the front. the steel plate you have there should mount into the holes where your original master cylinder mounts and the new master cylinder will mount to the plate. now that I look at it, they MAY have sent you the wrong adapter plate. Mark at ECI has been very accommodating and willing to work with me when I had a question or an issue. i was missing a few pieces and he sent them out right away. mine looks like this picture here. the three holes in the bracket fit into the three holes that hold the original master. This is kind of what the whole set up should look like Edited December 30, 2018 by belvedere666 Correction 1 Quote Link to comment Share on other sites More sharing options...
Robert Horne Posted January 2, 2019 Report Share Posted January 2, 2019 On my 48 Dodge, I used a Mustang II MC attached to the original MC with a bracket attached . Used a long push rod through the original MC.. Quote Link to comment Share on other sites More sharing options...

In my opinion the mounting bracket that they provided you doenst seem to apply to either styles Quote Link to comment Share on other sites More sharing options...
Dennis Detweiler Posted January 3, 2019 Report Share Posted January 3, 2019 Will a 1 inch bore dual master work well with a disc front conversion and stock drum rear? Quote Link to comment Share on other sites More sharing options...
