Thanks all.
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.
So.
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
Peter
