Single to Dual Master Upgrade

[pantone149]

Apostle: I did the exact same thing with hydraulic hose. My only concern is that the hydraulic hose might rub on the tie rods. If I ever get this thing bled I might swap the hydraulic hose for metal but that will probably require removing the fuel tank to do right. Time will tell.

I'm using plastic split loom for protection as I have concerns about the tie rods as well. I'm replacing the wheel cylinders soon and thinking about using DOT 5 fluid as everything will be new.

Pantone that is very odd that you cannot pull fluid through the system with a vacuum. In the past I never bench bled new masters, but the last few I have put in my other cars I have bench bled and it made it easier. I know it's a pain to do work twice, but at this point I would remove it and bench bleed to make sure there is no problem with the master.

Placing the reservoir inside the trunk is a better option than under the trunk on the master. Under the trunk the reservoir and its vent hole cap is exposed to all sorts of road splash, and that location is some what difficult for fluid inspection and service. The trunk is cleaner, drier, and allows ease of level and color of fluid inspection, and ease of refill, flushing. The fluid will stay drier and cleaner usually if reservoir is in the trunk.
In the trunk, I can easily see the fluid level and color each time I fill up the gas tank, no need to kneel on the ground to see it. I am an old fart and kneeling for that is easy no more. I know kneeling to look under the truck can dirty me clothes, and me hands. Heck I am afraid that if I kneel I may not be able to get back up!!!!

Plain ahead for your future, no one is getting younger, tick tock, tick tock, time marches on.

This got me going quite well. I'm using a 1967 aftermarket reservoir. The black cap came from a quart brake fluid bottle. I used a Presta valve because it's what I had around. I forced fluid from front to back with a bicycle tire pump. Got things started quite well, and fast too.

Not sure why your link didn't work:

So did you get the system bled out completely now with a high firm brake pedal? Good idea with the pump system.

[pantone149]

The system is doing "OK", not bad not great either. I think I need more driving around and then re-adjusting shoes. I also had to adjust the push rod a few times, but I expected that. I feel that the system is very bubble-free from pushing the fluid rather than vacuuming or pedal pumping.

I don't know which Samba member that I stole the cap/valve/bike pump idea from, but it's genius. The first pump told that things were going in the right direction. Thank you mystery Samba member!
