brake fluid remote res

[nzsimon]

I ordered a billet oil fill cap with my last shipment from yogi's it of course didn't fit as it was for a gm and I was guessing it might be the same as Toyota

Anyway I got a mate to turn up a threaded boss out of stainless and tonight I stated to make a resevoir (sp?) for the remote brake fill that will mount to the firewall

I cut a scrap bit of stainless pipe in half and tigged two sides on to it then welded in the floor
I cut a hole with a drill and a file for the boss to fit in in the top ( not shown )

I cant weld in the back untill I have welded in some hidden bolts and some pipes to hook up to the master cylinder

I have about an hour in this so far when polished it will look like a comercial  piece

Looks good Simon. Isn't stainless fun? I find myself using it more and more.

worked on it till the wife said spare the neighbours just have to tig two pipes in the rear and I can finish weld the rear on

It needs a lot of polishing as I scratched it all over

It is a little heavy but it will look cool

Very nice work, as usual, Simon!


I have questions about remote m/c reservoirs, which you or someone else may be able to answer.

Most m/c's use a flexible, bellows-type cover gasket, which allows the fluid level to fluctuate, without allowing the ingress of air/moisture into the reservoir.

When making remote reservoirs, what provisions are incorporated to prevent vacuum build-up, and to prevent moisture contamination by atmospheric venting?

I know the cap is sealed to the reservoir with an O-ring and it's sufficient to keep out air/moisture.   .....Is there an issue with "pulling a vacuum" inside the reservoir, or is it too minimal to be relevant?

If the bellows-type gasket is kept on the m/c, does it function as intended with the fluid level at a higher elevation?  ...(Assuming the remote reservoir is plumbed in BELOW the cover gasket.)

There are a bunch of the bellows type gaskets available, so when I make one I try to incorporate one in the cap. But if you think about it, the older ones just had a vent, so I don't think it's critical.

Great question on the bellows, I have been communitcating with ssbrakes on there remote set up see how it works and asked about the bellow and he thought I was asking about the reservoir which he says they use a vent valve to get the air out of the master cyl.  but yet to answer how they keep the air out of the reservoit.  From what I see they just have a sealed top and figure they have a small amount of air/moisture and by not introducing any new air/moistre it is not an issue.  This has been bothering me I want to just silver soldier some elbow fittings on the top of my mc cover and run them to a reservoir  the m/c is under the floor and the truck 50 F1 is my baby but not a show car but a driver.  Ed ke6bnl
Maybe a check valve to let air into the reservoir but not out so you don't keep getting an exchange of air and chance of condensation and moisture WHAT YOUR THOUGHTS??
