Loren Posted January 25 Author Report Posted January 25 I bought some early 50s car magazines and this ad popped out at me. The plan is to get my parts book out, copy the pages for the Chryslers with this kind of Power Brake unit and see how close I can come. There's a sign on a building near my storage that says a Power Brake Booster rebuild outfit occupies the building. I am thinking I will stop by and get educated on remote PB boosters. Quote
Loren Posted January 29 Author Report Posted January 29 I made a minor discovery today. The thread on the lid of the Master Cylinder is the same as the end cap where brake lines screw in. Which means if you want to put a remote reservoir on the firewall say, it’s easily done if you have an old master cylinder rusting away in your junk pile. The end cap has two holes for the front and rear circuits. It will screw right into the top and then you have a ready made adaptor for remote reservoir. When you hook everything up you can use a plug in the extra hole to purge the air from the master’s reservoir. I am putting in my VH44 power brake booster and figured this out because the end cap has two holes and I only need one for the booster signal, I have to plug one of them. I chucked an old rusty cylinder in my vise and removed the end cap with an 1 1/2 inch socket and an impact wrench. Cleaned and took it to my NAPA store for the plugs. ( 3/16 ths double flare is the size ) Once back at the shop I was curious to see if it would thread into the fill cap opening and it does. eBay has a cheap VW remote reservoir for $13 which will work very nicely. So Wednesday I will go back and terrorize the NAPA folks again for more fittings. I love it when a plan comes to gather! 2 Quote
Plymouthy Adams Posted January 29 Report Posted January 29 I found the floor mount master and cap very close to the floor plate when mounted so what I did for mounting the remote fill before upgrading to the modern master was to drill and tap the original fill plug and use a BANJO fitting for the inlet to the master from the remote reservoir and the sharp right angle made for ease of plumbing. With copper sealing gasket on the banjo fitting any position is available. The original cap has to have the vent hole plugged when used is the main thing to keep in mind. Working with the front cap and stock outlets makes fitting the 90 degree bend or adapters right against the floor I would think. Very doable but still likely close I would think. 1 Quote
Roofus Posted January 29 Report Posted January 29 It's interesting, but or do you connect the depression pipe? Quote

I discovered the same thing a few years ago and used an end cap to make an adapter for a pressure bleeder. 1 Quote

YOU CAN also just cut the metal stub of a banjo fitted to an old and discarded brake flex hose and slip the hose to the reservoir over this and clamp. If you referring to the outlet of the master to the brake cylinders, this item is not disturbed in this mod. Quote
kencombs Posted January 29 Report Posted January 29 Depression pipe? Probably on an iPhone, misspelled 'extension' and auto-correct 'fixed' it. Quote
Roofus Posted January 29 Report Posted January 29 (edited) Sorry,i mentioned this Edited January 29 by Roofus Quote
Plymouthy Adams Posted January 29 Report Posted January 29 your picture is showing a very popular style of remote servo/booster. Nothing at all related to the stock master and reservoir retrofit to this era vehicle currently being discussed. When fitted these are nice...when removed/bypassed the brakes are just as effective....you just have to exert a bit more leg pressure to the pedal.... Quote

Was asking just so we all could be on the same page. Don't scratch that knave plate, ok..! Quote
