Yes. Sorry. I should have made it clear. This is a Mini Clubman Estate.
1979 V reg. As has been suggested, if this was about a new BINI, I
would have posted on alt.autos.new-mini.
The battery is under the OS passenger seat.
I found a reference in Mini Spares web site wich confirms Bobs advice
that the larger (top) feed goes to the front brakes and the smaller
(bottom) feed goes to the rears. I anyone could confirm this that
would be good.
The pin is a different matter.
It goes in from one side - and has to come out the same way it went in
- because the plastic body of the reservoir gets in the way if you
simply try to drive it through the same way it was put in.
I'm now playing with a small G Clamp - to apply steady, yet increasing
and, hopefully, unrelenting pressure - but I shall have to insert a
packer piece - about 4mm thick - to support the plastic lug which bends
as I apply the force through the G Clamp.
The plastic moves OK on the pin - but as yet, the pin is solid in the
casting. Lots of WD40 last night. Fingers crossed but keep slipping off
each other. Damned good stuff WD40...
Heat is not a good plan I fear as the plastic would shrivel and die.
If I had BINI I could take it into the BMW Emporium and let the man (or
woman) fix it. But that wouldn't be restoration.
Thanks to all and any other ideas welcome
