Plan B:

£30 for the front set, inclusive of postage to Belgium. No Brainer?!

[peter-b]

Don't order 4 of those, you need a lh set as well. 2 of each.

Do you know if just the seals need replacing? It could be the bore is scratched up too and you need to resleeve it..

You must have been looking at the wrong spot on minispares, all the wheel cylinders are here:

These are your brakes .. go cheap if you want but I'd be inclined to spend more and avoid driving into the back of something one afternoon ...

Cheers Timmy850 - listed under 'hydraulics' didn't think about that!

 

OK, set from minispares it is!

OK, so,,,,,,,,,,,,,,, What do walruses & Tupperware have in common.?

 

 

 

Just to jump in on the possible confusion on the brakes though,,,,,,,,,,,,,

 

I do very much concur with all the other guys that it's telling you something and it might be wise to listen (rather than ignore it - which I can see you are not!)

 

999 times out of 1000 they will start to leak when the bore has rusted (and usually pretty badly) and so the seal can't seal anymore.

 

9999 times out of 10000, the cylinders rust because the brake fluid hasn't been changed in a while. Brake fluid is hydroscopic (it absorbs moisture) and the wheel cylinders so close to the roadway tend to absorb through them first.

 

Sometimes you can hone the bore (or even sand and then hone) clean enough to get them to seal again. For the very small cost of the seals, I'd suggest replacing them, though it's always been my experience that they don't last too long before rusting (and leaking) again, you might last until the next spring, but definitely something to keep an eye on. Almost certainly, the other cylinder on that wheel while maybe not leaking yet will also have some rust in it too.

 

The Seal Kits are normally intended as a maintenance item rather than a repair (though they can certainly be used for such a repair). OEM Brake Component Manufacturers recommend 'Servicing' the System every 2 years / 40 000 km and part of that service includes replacing all the seals (I have to say though, I don't know anyone who does it this often).

 

I'm sure you do already have it in mind to do so, however just to put it on the table, I'd suggest when you do go over to Disc Brakes, replacing also the flex hoses - front and rear as well. You will also have to replace the Rear Wheel Cylinders at that time in any case as the ones you currently have will be the wrong size. Also, I would suggest replacing the Master Cylinder, at the same time or at the very least, overhauling it.

Cheers for your input Moke Spider.

 

Do you think for the 3000km or so that I do every year, there is a noticeable difference between original & non-original parts. The problem now is how to actually guarantee 100% what you're buying is original.

 

I'm not penny-pinching, but don't like wasting money if I don't have too.

 

 

Ads for the joke:

 

What do Walruses & Tupperware have in common.?

 

 

They both like a tight seal!

 

 

cheers again

[b_sdaddy]

sorry, me again.

 

Going to whip off the front wheel and measure. Mine's a Mk4 from '78 but it is a non UK manufactured mini. What exactly do I need to measure.? Is it just the diameter of the piston inside the housing.?

 

 

cheers

[A-Cell]

Yes, the later ones are bigger. Measure the internal bore, 0.9375 inch diameter. While you have (the leaky one) apart clean and thoroughly inspect the bore. The rubber seal will be very hard by now. Then you can make a judgement as to the most economical method of repair.
If the bore cleans up ok then you could try a seal kit to get you thru until you change to discs. Only £3.96 retail at Minispares

[Spider]

Ha, cheers for that.

 

The Part you need is a Brake Seal

 

 

Oh, sorry, that's a Break Seal,,,,, wrong bit,,,

[b_sdaddy]

OK, so I've taken off the front wheel, and reluctant to start removing stuff. So, I've taken a photo and hopefully, someone will be able to spot what size I need.

 

It looks to me to be the 'std.' 15/16".

 

Can someone confirm please.?
