Pedalbox master inlet fittings advice please

[edk83]

Just put fluid in my new brake lines last night, all seemed well

Checked it this morning to find a puddle in my newly painted footwell

I need a 90 degree adapter out the master inlet 7/16 to an4

Couldnt find anything in this country, found a few for sale on US websites

Then I found these Aeroflow orb fittings and they said should work fine, well it's leaking, the inlet port is not quite a good enough fit on the rubber seal





Current plan is to take it off and put a copper washer on instead, annoyly I don't think it will clear the roll cage to take it out so may have to unbolt the master.

They sell straight 7/16-20 inlet adapters that come with copper washers so I dont see why that shouldn't work?



The American 90 degree brake inlet adpaters seem to come with rubber seals but built into a metal washer, is that the way to go rather than copper?

if both surfaces are nice and flat then the copper washer is the best option, rubber can fail over time, copper wont.

yes true! and its not a seal its just so we dont face to face damage out,
the seal is done on the taperd face, no flueid should go up the threds
edit soz is that a joiner ,

[edk83]

The tapered face in the master inlet port is convex, I've only been able to find 90 degree fittings with a convex so no joy, the fittings obp supply are concave but they only do straight ones which I have in the other two masters.

Just been out to remove the aeroflow fitting, couldn't get it out with the cage there, even with unbolting the master. Cut the fitting in half so now it's out!

Ordered a banjo eye and bolt, copper washers only option now.

When I bought the aeroflow fitting ages ago I did ask obp if a banjo would work and they advised against it. Suppose it's not as good as a tapered seal but it should work just as well.

The aeroflow does have the right tapered face for the master but it's not long enough to engage.

Couldn't put one in now without taking the whole pedal box out so banjo it is, at least it will be easy to position.

Banjos seal on the washer though don't they? If that's ok on the calipers then it will be fine on the feed

copper crush washer? best look that up, and dont it use a higher torqe bolt with strong threds,?
p,s is it on your tank down? i used jubily clips , i ment thers no presure so you must have a bad join

[edk83]

Well a copper sealing washer.

Yes the feed from tank, most people use rubber pipe and normal clips but I'm trying to be posh with braided.

[ardonfast]

you do a top job all the way through,,

The fitting with the o-ring needs a recess/chamfer on the female side to seal and contain the o-ring so that's why it didn't work.

Be careful not to over tighten the bango fitting bolt as they can easily shear due to being hollow

I have bought all my fittings and hose from these http://stores.ebay.co.uk/torquesuk generally if you order b4 4 o'clock they will be with you the next day the fittings have to be made up but once you get the hang of it they're not to difficult plus if you decide to change in the future tell joints can be remade with new olives. The only thing I have done is put a 1" length pice of heat shrink on the braided pipe so that when the system has been pressure tested I can cover all the joints so the nice mot man can't see that they are a made up joint rather than being crimped like the ones you have.

[edk83]

Yeah torques seem good quality, quite a few of my fuel fittings I got from them. Decided to use Venhill for most the brakes though as it's all dot approved.

Now has a banjo fitted and no more drips (for now)
