Another quick update - should be a longer one but my efforts were somewhat thwarted. Let me explain. Before I start doing things like putting on the rear axle and front subframe, I need to sort out the brake and fuel lines. The fuel line itself is fine after a blow through and wipe down as I'd cleaned it a few years, but because I changed from a single to a dual line braking system, the front to rear brake pipe is different. I had bought one for the project many moons ago and it's been hanging on the garage wall for a year or so. Amusingly, it has some orange overspray on it... Of course, the body was sitting on its trolley, something it's been doing for quite a while. Up went the front, followed by the back and the trolley was removed for the first time in years.

My plan with the brake and fuel lines was to re-use the clips which were factory fittings. Unfortunately (and unsurprisingly really) they were utterly crap. You could push the line in and it would hold for a few seconds before pinging out and, in this case, hitting me in the face. I had a few P clips but unfortunately the wrong type of bolts to fit them. I shall get some cap head bolts with a dome as they'll be the least obtrusive option as they will sit on a raised section under the carpet. I managed to get a couple of clips in on the bulkhead and the brake pipe is bent to shape. I just need to replace ALL the clips... More to follow.

Rear brake pipe fitted (but not entirely finished). Sorry about the overspray and amusing spiderweb!



It's finally off its trolley!

Well I haven't updated this for a bit because of three factors: 1) Time (I haven't had much); 2) Weddings (we've been invited to SEVEN this year) and 3) Heat. Anything over about 22 degrees and the Manroom turns into an oven. I think I accidentally gave myself heatstroke the other weekend as a result...

Anyway, Mrs Bounce gave up half an hour of her time by wielding a screwdriver, thus allowing me to fix the front to rear brake line with new P clips. The old factory fitted clips really were (for want of a better word) atrocious, so there was no way I was going to re-use them. I still need to do the fuel line, but I am sure I can grab an assistant from somewhere.

This morning I had a couple of hours so I did some little jobs (which of course take a bit of time). I resprayed the areas of the bulkhead which had been affected by overspray, as well as removing the brake valve, master cylinder & bracket as they too had been affected by the dreaded "orange fleck". I masked these and gave them a fresh coat of satin black.Whilst this was drying I popped in the bolts for the top of the front shock mounts. It's a really small job, but something that makes me feel good - another small bit is on the car. Finally I have started work on fabricating a small bracket to allow a more standard looking battery clamp. The previous one was bolted to the bulkhead "buttress" and looked dreadful. More to follow.

Some more progress has been made - there's been a small step back but that's hopefully sorted.

When I chucked the pedalbox in, I of course didn't check where the pedals were sitting. Due to the spring, they were sitting somewhere up near the dash shelf. And because of the design of the bulkhead, I couldn't get them back down without removing them. So I did just that, removing the homemade captive bolt plate, re-positioning the pedals, before holding them in place with something heavy (in this case my bowling ball in its bag - and even that struggled). I nipped up the nuts on the captive bolts and they sit where they should now.

The next issue was the master cylinder bracket. This was the original item on the car, which ran a single-line master cylinder. The main seal is significantly larger on the dual-line master cylinder (9mm difference in diameter!), so it won't fit properly in the bracket. The pedalbox is not an issue because the seal tapers - at least that's what I am hoping... So first thing was to cut a bigger hole in the bracket - no problem I thought - I have hole saws in my set of drills. The only trouble was, this was a cheap set of drill bits (it was a present), and all the hole saw did was make a small mark, get very blunt and cause the wood underneath the bracket to smoke wildly. However, I am nothing if not resourceful. Using the hole saw mark, I cut several slots in the metalwork, bent them out with pliers and then cut them off with the Dremel before giving the whole thing a tickle with the grinder and tidying up with the grinding stone. Granted it's not particularly professional, but now there's lots of clearance and nothing catches. Just needs a coat of paint and all should be fine.

The other day Shaun came over and despite him having a horrible week at work, I put him to work holding the screwdriver whilst I sorted the P clips underneath holding the fuel line. It still needs a couple of more accessible clips in the engine bay doing (and holes drilling for them!) but the awkward bit is done. Whilst I was underneath, I also sorted the remaining heatshield for the exhaust. Again, it's not perfect, but the only person seeing this will hopefully be the MOT tester, and the majority of it will be hidden behind a subframe, a gear selector and an exhaust so I am not too bothered about how it looks - it's for stopping the bulkhead catching fire, not looking good. This of course left me the wonderful task of the steering rack. Anyone who's done one on a Mini will know that they're utter bar stewards when the subframe is on, so I was glad to put it on now, without that large lump of metal being there. It's still awkward when you're doing it on your own, but a carefully placed piece of wood allowed me to pop the U-bolts through (no I didn't forget the little plastic anti-friction strips). I nipped up the bolts to hold it there, although it does need a small amount of adjustment which can wait until next time. Finally, I popped the freshly repainted brake valve back on the bulkhead. This took significantly longer than expected due to the inaccessibility of the nut, but some careful use of a small socket and believe it or not, some cable ties sorted the situation. More soon!

Pedals now where they should be.



Hole saw a bit rubbish? No problem - use a bit of back-street engineering!



A tickle with the grinder and it looks acceptable. It won't be seen anyway...



Fuel line now held in place - cheers Shaun!



Heatshield now fitted up to the selector area



Rack now loosely in place.



And brake valve fitted to the bulkhead.

I don't like Mini braking systems. Mainly because over the years they've been messed about with BL / Austin Rover / whatever they were called that week penny-pinching numptiness. The plan was, as my single-line Cooper S Master Cylinder was kippered, to convert to a dual-line system using a yellow-tag MC and limiter valve on the bulkhead as I also wasn't keen on using the rear valve (VERY rusty). To date I have acquired brand new brake lines all round, an FAM7821 valve (Secondhand) and have rebuilt the s/h yellow tag MC. All new front to rear brake line is fitted. Excellent I thought - I will connect everything up.

Problem 1: The thread to the rear brakes on the valve is knackered. Tightens up so far and then spins on itself. And as it's a blind hole I can't re-cut the thread. New valve then - that's £87 I don't have.

Problem 2: My yellow tag MC and brand new clutch MC do not fit together on the same base plate. There's precious little clearance between them, but add a couple of pipes and they simply don't fit. I am either doing something drastically wrong or fitting a yellow tag is simply out of the question. To put it back to the way it was, a new Cooper S single line MC is £72 I don't have, plus I would need the regulator valve at the back (another £73 - and it's out of stock).

I have closed the garage door and walked away before I pick up something dangerous like  a blow torch and some petrol.

This is junk...



...and these two bar stewards don't fit together.

Cant you elongate the mc holes a little to allow you to slightly rotate it and make the clearence?

Well, it seems that things are looking up again. Thanks everyone for your suggestions and offers of help. It seems that the original "tin can" clutch MCs are the ones to go for, so have a s/hand one coming which will be reconditioned before fitting (trial fitted first of course!).

In the meantime, the brake valve Ian had in his shed (cheers matey!) has been received, and tried out. No issues with the thread on this bad boy - it tightened up a like a dream. However, it did look a bit... how do I best put this... used. So out came my favourite tool - the angle grinder with the wire brush attachment. It made short work of the minor surface rust and odd paint, and I wiped it down before plugging up the holes. I've given it a coat or two of primer before it'll get the satin black tomorrow.

I also finished tidying up the "T-bar" I made to hold in the spare wheel and gave that a coat of primer too. More to follow.

Brake valve looking pretty again.

Forums. There's only one thing that I can say about them - they're brilliant places. Not only did I get myself a brake valve from Ian, but a "tin can" clutch master cylinder turned up for sale at a very reasonable price as well. So after a short email conversation involving the wonders of Paypal, I had myself the part that I needed - well, mostly. I knew it would be a used item, so the best thing to do would be a recondition, despite it working well before removal. So I picked up a seal kit (not expensive - about £7) and when the MC arrived, I started on making it more presentable.

It had been on a fuel-injected Mini all its life (one of the later ones) but it was still 17 years old. It was also a little bit in need of a clean. So I removed the circlip, and took all the inner gubbins out before giving it a good dunk in the parts washer, followed by a proper clean up with various brushes and the Dremel. Once properly dry, I gave it a couple of coats of primer, followed by some satin black. I've replaced all the seals - now all that remains is for it to go back together.

Oh, and yes, it fits perfectly!!

As received. 17 years of grime yet to be removed...



Much cleaner after a dunk and a brush.



All the inner workings ready to be replaced



Primed...

This car is fighting me. A lot. It's almost like it wants to frustrate me at every given point just to irritate me a little more than before. Allow me to write the latest tale of woe.

I finished off the clutch master cylinder by popping in the spring and piston with its new seals and washer and sorted the circlip with a flourish. Everything seemed to be going according to plan. I popped the master cylinder into place and proceeded to connect up the brake master cylinder's pipes to the bulkhead valve. All looked great. "Excellent" I thought. "Time for the slave cylinder pipe and to connect the new pipe to the master cylinder". Except when I offered everything up, the new slave cylinder pipe was too large for the hole in the bulkhead bracket. I REALLY don't want to remove this bracket again as it'll mean taking out the pedalbox as well as I can barely see the blots with it on. And I don't have a 5/8" drill bit. Arse. I shut the garage door and walked away for a bit. Again.

To cheer myself up I decided to do some Midas paperwork. It's not much, but picture below.

New MCs fit well together. ("Old" new MC has been sold already)



Hole needs to be this big.



However, it is this big. Guess what won't fit...



So I sent this off. Just because.

Sorry to see you struggling. It looks like very good progress was being made.

5/8" is very slightly smaller than 16 mm (5 thou). I don't know if you have a 16 mm drill but I would use that without any worries.

I hope you can forgive it and get back to it soon.
