I can look into them if there's demand, it's usually the diff side cover bushes wearing that cause leaks rather than the seals themselves.

Picture coming soon, maybe of interest to some https://minispares.com/product/Classic/ ... MC153.aspx

I have known about these for a while

A great addition to the range. And to a great extent, driven by discussion on this very forum.

That is a great addition!

I was really hoping it was going to be 7” disc brake drive flanges. I know they would be costly, and probably not nearly enough demand to make worthwhile.

TIN TANK BRAKE MASTER CYLINDER SINGLE LINE 0.75" BORE - GMC153
"The GMC153 is the early 0.75" BORE BRAKE MASTER originally used on 1959 minis to approx 1963 with single front wheel cylinder per wheel drum brakes and most 997 Cooper with booster valve and 7" disc brakes. Also fits Austin A40 Farina Mk2.
Originally the top of this master cylinder would have either a removable union top shaped like a nut, or a smaller hexagonal nut shape machined into it, unfortunately these parts are no longer available,therefore the only alternative was to have this copy made with the flat topped shape as this was the version that was made once the hexagonal nut type ceased production.
This looks much more period correct than the later cone shaped top versions, and of course is the correct bore size to suit the early brake systems. This cylinder also has the original size small base foot."

TIN TANK CLUTCH MASTER CYLINDER FLAT TOP - AAU4969FLAT
"Flat top clutch master cylinder to suit PRE 65 minis.
Originally the top of this master cylinder would have had either a removable union or a small hexagonal nut shape machined into it, but neither of these options are available so the pipe goes directly into the flat top as per normal but the outlet is period correct.
The later master cylinders post late 1964 have a more pointed shape where the brake pipe comes out.
Ensure the correct DOT4 or DOT5.1 brake fluid is used as these cylinders are not designed to use anything else such as Castrol SRF for racing or any mineral fluid."

So reading the Minispares descriptions above - they will have a flat top but not the earlier Nut union/Hexagon shape top as seen on the reproductions below?

That's correct yes, tops are flat but no hex. Posting some pictures on social media this afternoon

There is also this more period correct 3" tall Cooper S master available, details below:-

TIN TANK COOPER S BRAKE MASTER FLAT TOP - GMC172FLAT
Correct flat top brake master cylinder for pre 65 Cooper S.
"Originally the top of this master cylinder would have had either a removable union or a small hexagonal nut shape machined into it, but neither of these options are available so the pipe goes directly into the flat top as per normal but the outlet is period correct.
The later master cylinders have a more pointy shape where the brake pipe comes out.
3" high canister as opposed to std Mini 2.3/8""

Also upgraded are radius arm/upper arm seals, imported from Japan these should be much more durable and price remains the same.

Glad they are starting to introduce what hopefully will be a better quality seal. The current ones literally disintegrate while your car is being built

Duplicated

Not wishing to 'out' anyone, but is 't3gav' the PA / public oracle of a certain bearded Guru long since believed to be extinct?

Come back, beardy one, all is not lost!

Al

No, it isn't.

I know who t3gav is, but it's up to him to introduce himself if he wants.

The reason Rich / Guru left the forum was that people conflated him as an individual & him as the guy who worked at Minispares.

We all miss Rich on here for sure but some of us are privileged to receive his wit and humour via PM's

Back on topic, it would'n take a lot to drill out a nut and glue it on top for the "look".

Great to see from MS. Were these fitted to all single leading show brakes ?

Which seal do you mean Rolseyboy ?

I think it was this Minispares upgraded seal linked in my previous post below.

That's what I was thinking might be possible to do for our '59 Mini restoration.....maybe a new product line for the CatMint Shop?

Hey, I recognise that orange moke bonnet!

Bodysides now available https://minispares.com/search/classic/24a236.aspx

These new Minispares Body sides look absolutely amazing!

Was speaking to Rich about them last night.

And about 1/3rd the price of any others currently available
