1946 Dodge New Master Cylinder Brake Issues (Video)

[Beatles65]

Well we purchased a new master cylinder for the car as it was the best route to go. The old one had pitting and no prim. I installed the new master cylinder and bled the brakes a number of times, going from the farthest to the nearest wheel. The new master cylinder does have better prim but doesnt come back up after being pushed down or when it does its very slow so you end up having to pull her back up. What is going on? Is there the possiblilty that air is still in the lines somewhere? Something else i over looked?

Here is a link to a video on youtube to show you what its doing.

Thanks for the help!

I am pretty sure you should have a return spring connected to the brake pedal to assist in its return. Also seems like you have a lot of pedal travel when brakes are applied. Are your shoes (assuming you are using stock brakes) adjusted correctly in association with the drums. If not it can cause the illusion of air in the lines or too much pedal travel. No expert, just my 2 cents.

Your missing the return spring. The black spring in the picture is connected to the brake peddle. I think it just hooks into the side of the frame on the other end but look for a tab with a hole for the spring to connect to your peddle where the bearings are located. Hope this helps.

This is just a closer view on the area the spring connect to the frame.

I don't see a spring either!

Ok so I had the spring in the wrong location. so I installed it to where I think it should go. My question now is if I have the right spring or not. The one in the picture below seems to be much larger than the one I've got. Also is the spring anchored in the right position, look closely at the frame and clutch return spring, there is a hole in that location, is that right? Otherwise there is another hole location closer to the master cylinder and thats the one i was using before with the spring I have. If I use the one farther back, closer to the big clutch spring it doesnt seem like it would reach.

Thanks for the advice!
