Remote fluid reservoirs for 'standard' Master Cylinders??

Post

Back to the top
I've had an idea (possibly stupid, but there we go) and intended to run a 'standardish' type brake Master Cylinder with external remote fluid reservoirs.

Problem is I'm finding it impossible to come up with a way of attaching the fluid transfer piping to the Master Cylinder, cos it's got the standard rubber bungs in it to fit the 'standard' plastic reservoir that sits directly on the top.

Has anybody ever tried this? I've managed to source everything I need and it's all sat here but i can't join it all together :'(

I would suspect that if you find a "pipe" fitter, or a Machinist to either make you a Fitting to go in to the Bung Plugs, and or to take your MC apart, and Machine the "Bung" holes with a threaded fitting, so you can screw in a bung.  The Issue that I see, is that you are going to have to have a "hose" made to go from the RES to wherever you make the hard point it. Because I would think that hard/fast pipe connections would vibrate and torsion shear or hole..and you don't want to find out "by Accident"  Then if you got in a wreck, and they discover your brake improvement, it could make you liable even more so… Even now-a-days, most vendors, still use the tried and true res/bung.  I find that K.I.S.S. is usually the best way. (Keep It Stupidly Simple).  My two pence.

What do Divorces, Great Coffee, and Car Electrics all have in common?

They all start with GOOD Grounds.

Where are my DIY Links?

Hmmm, cheers mate.

Yup all car manufacturers seem to use the bung principle, however all aftermarket M/C's for race use etc all have threaded mountings on the M/C, hence the issue.

I might have to re-think and find a 'standardish' fluid reservoir.  O_o

Hi Ian,

I know this is a blast from the past but did you ever get anywhere with this?

Cheers

What is the advantage of the remote reservoir, with the standard location of the MC in a Mk1 Golf?

I can understand the advantage if it were, eg, down near the pedals….or underneath the car.

Hi Paul in my situation it's right in the way of everything :( IMG_20200529_132528372.jpg IMG_20200529_132534205.jpg

Rich. Short answer is no.

I had removed the brake bar and the power assistance and have the master cylinder connected straight to the brake pedal. (Before any one goes nuts it's the way the mk1 polo does it) The idea in the beginning was to mount it out of the way due to bike carbs catching it.

After a bit of research I couldn't find anything and mocked up some stuff but eventually went to the scrappy and got a load of reservoirs of different sizes and shapes. I found a Rover 25 one fitted the M/C and due to the shape missed the carbs.

Just had a quick search of ebay to find one but there doesn't appear to be one on there. However this did pop up

https://www.ebay.co.uk/itm/Wolfsburg-West-Brake-Fluid-Reservoir-VW-Beetle-1967-only/283301668801?hash=item41f61867c1:g:c1oAAOSwVo5egtRD

Makes me wonder if the ends of the pipes could be adapted?

Find the right size pipe, double flare it at the end and stick it in? (x2)

Its only under the pressure of gravity of the fluid. Of course, the reservoir needs to be above the MC.

I've never found the linkage to be an issue. And if it were, say for racing etc, then use a LHD car with the added bonus the weight distribution is better.

Hi Paul,

Thanks for the suggestion. There really is quite a bit going on between the coolant reservoir and master cylinder and don't want engine movement causing any contact.

I have measured the existing barbs on the reservoir and the non barb section is 13mm and barb 15 to 16mm.

I can't trust the accuracy of the after market part so have have purchased 2 types of 90 degree barb and then clear hose to the reservoir that i will mount near by (most likely above the brake servo bracket).

I'll get some photos up when I have a working solution. I'll try to keep my current reservoir as it's quite compact.

Cheers
