4 pot disc`s + heater valve
Discussion
hi just robbed a metro of it`s brakes and head but how do you fit four pots pipeing to a mini . on the head where the heater valve goes on a mini there is no water hole do i need to get this drilled out or is there another way to do this . one more can i use the long cluch arm if i fit a servo or do i need the short one thank you david

Metro brakes, you need a set of conversion hydraulic hoses from just about any mini specialist. Metro's used a different location for the heater tap but you can simply drill out the closed web. Clutch is a bit more difficult. If your mini has a standard type clutch with the long actuator arm, and the metro had a Verto clutch with the short actuator arm the simplest thing to do is get a Verto slave cylinder, a Verto hydraulic hose and a Verto mounting bracket and convert it over completely. Alternatively you could remove all the clutch and flywheel assembly from your old mini engine and fit it to the Metro engine and keep the original clutch bits. Unfortunately a mix-and-match of the two doesn't work.

i have both cluth`s so dont mine which i use but with the long arm will there be room for the servo
with the brakes can i use the metro hub and drive shafts
to drill the head can this be done diy or does it need to be done by a pro thank you
I converted my 1990 Cooper from Verto to standard Mini clutch and retained the high-level servo. I used some special braided hoses (available from MiniSpares) to replace the rigid lines from the master cylinder to the bias valve on the bulkhead. That way I could have a proper competetion clutch with a lightened flywheel and retain the servo. I can also remove the servo and master cylinder to access the clutch if necessary without having to drain the fluid out.
All things considered the original Mini clutch is a better prospect than the Verto; better parts availability, better durability, lighter weight flywheel etc.
It is possible to use the metro hub uprights with early metro ball joints on a mini, but from what I remember there is a problem with suspension geometery, caster or camber angle can't remember which. If your mini has disc brakes already use the existing uprights as they are. You need metro drive flanges to match metro discs, the caliper fits on the mini upright but you need some sleeved or shanked bolts. The hole through the metro caliper is bigger in diameter than a mini one, so the unthreaded section of the bolt is a bigger diameter than the threaded bit, if you see what I mean.
You should be able to drill out the web at home, just be sure to clean up the swarf afterwards.
Can't add to that except to say that when you drill out the water valve hole, hold a vacuum cleaner pipe close to the drill tip to suck up the swarf.
The original type clutch is definately the best. Remember to use the correct starter ring as the pre-engaged type use a different ring from the inertia type.

Good point, I forgot about that. You should use the starter which matches the flywheel. Also doing so will mean no problems when rewiring the starter. Depending on the age of the mini your fitting this lot into the solenoid may be on the near side inner wing, or if a later model it may be integral with the starter.
Edited to say : Sorry that should have been offside inner wing for the solenoid....... No room on near side 'cos the rad's in the way !!

I learned something else recently. The 1990 onwards Coopers have the engine moved about 1/2" forward to give a bit more bulkhead clearance.
With the pre-engaged starter with built-in solenoid there is then very little room for a decent sized oil cooler behind the grille.
On my 1990 car I'm moving the engine back, which means an earlier gear linkage and shorter top steady arm, then going back to an inertia starter and wing mounted solenoid.
The rear mountings for the gear linkage are very sloppy with the standard rubber mounts. A good mod there is to use a pair of the original Cooper 'S' remote gear linkage rear mountings, cutting a bit off of each, then drilling 4 additional holes and replacing the original rubber mountings with these. They really are very strong in that application.

think i may have taken to much on but i keep going.
Hhhhmmmmm.
Iv'e started so I'll finish. Know exactly where you're coming from there
What started as a tidy up has become a rebuild/performance upgrade which is not going to be finished before I move house........
Wonder if I can leave it there and pop back to finish it later....?
Best advice young man is to just push on when you can and don't set deadlines.
Yes, the deadline for completion of my 1990 rally car project is fast looming as is moving house day. It's a nightmare!
I seem to be working on the Mini every evening as I must get the engine/box in before I move due to my not having a lifting beam available in my new garage/workshop initially. It may take a while to get the timber workshop built and until then I only have a 2-bay double garage, but loads of tools, bits and, of course, my 2 Mini rally cars.
Still, in the longer term it's a good move as I have space to build a big, like 16ft x 12ft timber workshop alongside the existing double garage, plus the advantage of no immediate neighbours (can angle grind at midnight, maybe!).

Had to have it , it was a bargain .

Hi Rog,
I'm working on it as much as possible. The main part of the preparation is now virtually complete. Last night I fitted the washer bottle inside the car in the LH front footwell just by the roll cage, together witht he pump.
One more full day should see the wiring complete.
Engine is going back together and I get the completely re-built box back today. Just waiting for the MG Metro cam. Head is in the machine shop having the valve seats re-faced.
Call round and have a look.

Be carefull, you'll get Environmental after you for disturbing the sleeping water voles or somesuch.
Noise carries at night...
reminds me of a story a few days ago, the street light designers have to install a scheme to give safety to folk out walking in a dark area, thought to be a bit of a problem area for muggers, sniffers etc but have been told to design it so that the light doesn't disturb the otter colony that are known to live in the area.
Was trying to buy a trailer to shift my car (when I get the engine in and suspension connected) to Scotland in September/October but the one I was interested in has been sold. Anyone got a minisized trailer for sale (or rent) in the north east of England?

I always liked the look of those, are they as good as they look ?? I'd love to try one, hopefully being about 6 foot wouldn't be an issue.........
