The picture of the arm that i've posted before shows how i've modified it to avoid a potential issue , if you looks carefully, you'll see where it was cutted and welded by myself :lol:
But once again you know better than me what i have done, it's so funny :lol::lol::lol:

You are the master of contradiction I'll give you that.
do you really understand anything that's being said here or are you truly incapable of reading/comprehending simple sentences?

There is not one person here that cannot see (apart from you) that I stated that you'd cut/welded the bracket.
My previous comment for the hard of thinking:

It works just fine and unless you can cut/weld or have someone do it for you then it's the easy/only solution.

He modified them to remove a 'potential' problem.

It is quite obvious to everyone that you are just trying to create issues and making stupid comments to try and satisfy your own ridiculous ego.

Well, show us these PMs, please!!!

I already showed a snippet of your two-faced persona.
As I already stated this brake thread is not the place for discussions about the (apparent only to you) difference in some pistons.

How can you say at the same time that you don't understand them and that also you were able to answer to them

I never once claimed to have answered your questions to your satisfaction (tbh I have no idea what that even is as you're ramblings make no sense).
But I gleaned enough understanding to know that you were talking drivel.

Show us how "great" you are!!!

Why would I do that? You seem to place a lot of importance on how great I am.
You seem to be the only one doing that. I'm a little worried that your adoration of me is going a little too far. Good job we're on different continents and we have guns here just in case you do get too close.

:lol::lol::lol::lol::lol::lol:

You post a lot of those emoticons. Seems you think something is very funny (and I'm guessing you're not laughing at yourself the way others are). I'm guessing the jokes got lost in translation.

Are you pretending understanding French?

WTF!? Why do you keep making such stupid comments? You really are obsessed and maybe a tad retarded.
I've never claimed to understand French, where did you get that stupid idea?
I do understand enough to get by. But if that means I hear more from you I'm willing to forget it all.

Oh ,dans ce cas fait donc preuve de la grandeur de ton immense intelligence plutôt que de te montrer si pédant et arrogant...

No-one needs evidence of my greatness or intelligence, you're on your own there.
My pedantic manner is well documented and I'm proud of that.
Although as an Englishman I leave the mis-placed arrogance to you ( French stereotype that this one gives much creedence to)

I'm still sure you still don't understand what about i were talking about these pistons, pleaseshow me i'm wrong... ... with proof please, and stop be so funny:lol: , be serious if you can...

I understand that you talked about tow different B20A7 pistons and 'claim' they are different. You then send me two pics from very very different angles and 'claim' they are different. You then 'claim' they give 0.2 raise in CR. Which you 'claim' can be seen on the piston crown.
I understood (because I'm good at translating gibberish) what you were 'claiming'. And due to what you stated yourself: "Well, i'm happy to "talk" with you because you seems to understand very well". But didn't feel it was worth my time to get in to a lengthy discussion about mere 'claims' with no evidence.

So instead of trying to get others to prove things that they weren't claiming at all, why don't you give proof of what you are claiming?


Oh, there's that hypocrisy again.

...

How many time have i to apologies about the fact that i'm not English nor american and that i try to write to you with a language that is not mine???

How many time do i have to explain that the missing of a coma in one sentence may change the translation of what i want to say and also of what i have to translate to understand you???

I'm sure i look retarded to your eyes, it's an evidence, but if you try to use your brain instead of being so contemptuous, you'll understand that using a foreign language is nearly like talking to a child or like a child:

it may be sometime difficult to comprehend and to be comprehended...


If it's too difficult to you to make more simple sentences, or simply asking me what i want to says without joking me or using "not gentle words" , so don't write to me , that's all...

I own Prelude since 14 years now, i think i begin to know them a little bit, if i say that there's two type of "EC" pistons mounted Inside the B20A7, that there's two type of head (pk2 and PK2Y) mounted on the b20A7, that the pistons are a little bit different, i think that you can believe in what i'm saying... mainly if i show you pics....

I understant that my pics are not really accurate and i wrote it that i know it , but you can read on them "PK2EC" and "PK2YEC" on the top of the pistons, isn't it a proof of their difference?
I tell you that i compared them side by side, i only forgot to take pics, but the dome is a little bit higher on the "pk2yec", i saw it!
Well, you don't want to believe me, ok, but if i'm right, you have some B20A7, no? Maybe one day you'll see it by yourself, and this day, remember who tell you that it was true...


Well, that's it, me and my stupidity tells you goodbye once again Jon, i'm so sad to see that i was wrong about you thinking you were a good guy and to discover how much you are arrogant and pedant.
You don't make me laugh now, i have pity for you, maybe one day you will change another time.

...blah blah .. blah....

I used to make allowances for the language barrier but not any longer. Now you simply use that as an excuse for your irrational and unacceptable behaviour.
It is not the language that is the problem here, it is your attitude and persona.
The same persona you have used many times when attacking other people.

Yuo still seem to be having issues here.
I've not once said that they don't exist, or that I didn't believe youi. I simply said that without better pics or other evidence their is no difference to see between them.
And even if there was a difference to give the 0.2 CR raise you 'claim', it is not enough to get worked up about. Nor is it enough to make it anything other than a curious difference.

I understant that my pics are not really accurate and i wrote it that i know it , but you can read on them "PK2EC" and "PK2YEC" on the top of the pistons, isn't it a proof of their difference?

No. It is proof of two different part numbers, nothing more. Honda often use different part numbers for identical parts.
Remember you initially said that one was PK2A.

I tell you that i compared them side by side, i only forgot to take pics, but the dome is a little bit higher on the "pk2yec", i saw it!
Well, you don't want to believe me, ok, but if i'm right, you have some B20A7, no? Maybe one day you'll see it by yourself, and this day, remember who tell you that it was true...

Well with the evidence you've given so far there is no difference worth noting, certainly not enough to cause all this fuss over.

The two pics I had for comparison for anyone curious:

http://i14.servimg.com/u/f14/11/27/92/20/stp82411.jpg

The two different numbers on them was never in question.

Well, that's it, me and my stupidity tells you goodbye once again Jon,

Like the boy that cried wolf.....

i'm so sad to see that i was wrong about you thinking you were a good guy and to discover how much you are arrogant and pedant.

You carry on believing that, it makes no difference to me. :lol:

You don't make me laugh now, i have pity for you, maybe one day you will change another time.

Yeah, never going to happen.
Your biggest mistake was thinking that I would change, never have, never will, ask anyone on here for confirmation.
So I'm still the person you asked for help, still the person you said was so good and helpful, still the same person you claimed to like so much.
You're the only thing that has changed here. Or rather your true persona has been revealed.



Anyway, enough nonsense... let's get back to brakes.

 

[SEVEN]

...


Well that just shows your lack of knowledge, particularly in the history of such things.
Do some research.
"Not exactly" is quite simple, I don't use discs for the ZR as they weren't available when I first did this mod. So I used what was available at that time, the discs from a ZS180.
The ZR then followed by using the same braking system that was used on the ZS. Hence not ZR discs but the same specs, as I stated.
Maybe it was too tricky for you to comprehend.
Yes, maybe I look stupid. But oddly I don't really care one iota. Because if you're the smart cookie here I'd rather not be in the same category.

;-)

Oh oh, i've done some research about this "point" of history, and guess what... ... it appears that the firts car launched by Rover/MG was the ZR and not the ZS...
What are your thinking about that? :baa:

 

[lorby]

Hi Sean, I've just followed your guide for the Mini cooper S rotors on the front after I screwed my MG ZS 180 rotors and had trouble finding the replacements. I've used the 5mm spacers and the caliper is definitely biased to the inside of the rotor. There's about 0.5mm of clearance to the outside edge of the rotor and a couple of mm on the inside. It was my understanding that the rotor should be as centred as possible inside the caliper. Is that correct?

edit here are some pics so you know what I'm on about:

 

[1funryd]

Yes you need space that other side and center the rotor as much as possible.

 

[lorby]

What I'm asking is why does the guide call for 5mm worth of washers/spacers. My pics are with the 5mm worth. It looks like it needs more like 6mm.

It was the size that ended up using that worked for me. As long as it clears and is as centered as possible your good, because that is the bracket thats being spaced the disc stays static and so does the bracket, its the pads that move as they clamp and wear over time.

 

[lorby]

Having a look at your pics again though it is nearly exactly the same as mine, big gap between the inner inside of the rotor and the caliper as well.

OK if its like yours you are good. Because it does not move.

 

[88SE Lude]

It was my understanding that the rotor should be as centred as possible inside the caliper. Is that correct?

Yes that is correct, with the proviso that it is the carrier you need to be centred in, not necessarily the caliper.
The more off-centre it is the more likely the potential for problems.
Discs/rotors have run-out. The rotors and calipers flex.
Any of this movement could cause rubbing etc if you're already close to the carrier.

 

[lorby]

That was my thoughts too. It has taken an additional 1.4-1.5mm to be close to centred inside the caliper. This is a with a 17CL15VN caliper with a 23T carrier, it really needs more like a total of 6.2-6.5mm worth of spacing to be centred correctly.

 

[88SE Lude]

Is this with the MINI rotors?
I suspect so as they have different offsets to the rotors the carriers were designed to be used with.
Do you know the thickness of the rotors?
The 23T determines safe rotor thickness.

Just make sure everything clears properly to avoid any nastiness.

 

[lorby]

Yes, the same mini cooper rotors, 22mm thickness. As you can see from my pics before the 5mm spacing is not enough on my car. It doesn't touch while just spinning the wheel but I wouldn't trust it with that tiny amount of space on one side. Using the ~6.5mm spacing it gives around 2.4mm on either side of the rotor.

 

[Austro]

Hey lorby, so you tried two 3.2/3.25mm spacers and it definitely sits better?

I haven't seen the pics, I'll take a look back.
But having them as central as possible is a big :emthup: from me.

 

[lorby]

Hey lorby, so you tried two 3.2/3.25mm spacers and it definitely sits better?

I actually had custom 12x30x5mm spacers made up, which is a bit of a bummer for me . Used them in combination with some roughly 1.4mm flat washers and now I'm left with 2.25mm on one side and 2.65mm on the other. Not 100% ideal but a million times better than it was. I would say 6.5-6.6mm for my car would be perfect.

I haven't seen the pics, I'll take a look back.
But having them as central as possible is a big :emthup: from me.

Yeah definitely, that's how I first damaged my MG ZS 180 rotors, being 25mm thick they left a lot less space on either side, on a free spin there was no touching, but once I got the car out onto the road for a test drive and everything shifted/heated up slightly the caliper started touching one side of the disk and left a nice groove.


EDIT, here are the pics for reference:

5mm spacing outer edge


5mm spacing inner edge




6.4mm spacing inner edge



6.4mm spacing out edge

 

[1funryd]

I have my rotors just like the yours pictured before you changed it.

If you have concerns just adjust to suit, for me I have been running the lude for over a few hundred miles and no issues.

It spins freely and I do check it after every drive. So for now I will stick with it, but if I see issues that you and Jon state I will just adjust.

 

[Austro]

Hmm and that amount of washer spacing still fits fine on the 30mm bolts? I might go with that much for when I do the swap next month then to be on the safe side.

 

[lorby]

You can adjust the washer on the head of the bolt however you wish to make it fit. It's only purpose is to adjust how far the bolt goes through. I'm using the factory spring washer and it's pretty much the perfect length
