Cusco brake stopper anyone ?

[Dale_V]

I had one of these, it didn't make any difference at all

And sure there is a difference.

well no, not for sure. There was no difference on my car, fact. It may make a difference on some mr2's, it may not on others.... it didnt on mine

[Will_bmx]

Looks easy to make- might try and knock one up this weekend

I was thinking the same thing. Only I'm lacking in a welder, jig, lathe and any metal. haha.
I'll see what I can do with some old bmx parts and abit of ingenuity!

Dont think I'll need a lathe or a jig to make that- then only thing I'm missing is some nice round tubing

If I get round to it I'll post pics

They must make some difference, you can see my servo and cylinder moving around if you stamp on the pedal hard!

[Ren0W]

I presume the ebay copies are poorly designed and dont go straight on?

The example pics are of my car.. I purchased that Cusco one from RHDJapan and it just went straight on, no fuss. It used mounting points that are the same on all MK2 body shells.

Please explain to me why it would be a fake item?

[toxo]

Right, I've just fitted a brand new one of these I got from Cusco.

First off, the stopper comes with a longer bolt for hole number 2 when you buy it new, which explains that one. I took a few photos which may help you - as you can see the bolt on mine had to be screwed further in than the first photo posted (which is a UK car, so has a different servo again), but not to its full extent like Ren0W's. You can see the difference in servos where the vacuum feed from the engine attaches - on mine it's on the passenger side, on the photos of the car in the first post (with the black spare wheel) the vac feed is on the driver's side.

Ignore the ABS sensor and the speaker wire

Before:


After:



I think it's changes in combinations of master cylinder and servo during the various cars histories that cause these inconsistencies. Rev1s have a smaller servo as well as a smaller master cylinder. You can spot a rev1 cylinder a mile off because the reserviour is cylindrical where the rev2+ one is not. There's then a different master cylinder if you have brakeforce distribution which has a more square reserviour. The noticeable difference between ABS master cylinders and non ABS is that non ABS, both brake pipe exits are driver's side. But you can't have brakeforce distribution without ABS and these stoppers don't work with ABS so that's all a bit irrelevant.

My conclusion is... Ren0W has a rev1 or european-market brake servo. Does it have a part number on it?

Edit: One other thing I noticed - put the ground wires (the 2 white/black striped ones that the stopper bolts onto) on top of the stopper support arm as per my photo, not underneath. Both the surface of the stopper support arm and the surface of the car are painted, so it needs to ground through the bolt (unless you have taken the paint off those surfaces).

You should also have a nut on the stopper bolt to lock it all together once you've screwed it tight against the cylinder.

[Ren0W]

Found another big bolt, and this is how I solved it.

I couldn't find any partnumber (unless it's the sticker).

But if I got a rev1 one, what could be the reason for it.
Pure ignorance of the previous owner/garage?

And am I missing out on some great upgrades regarding a rev3 one?

And what's that other small reservoir ?

[toxo]

Other reservoir is the clutch, I don't think you need to worry about that

The solution you've come up with will work fine so no worries there. It would be nice to know once and for all as to why yours is different though!

I will get an equivalent photo to your 2nd one next time I have the frunk in bits and we can compare

[Ren0W]

Maybe some Paul, Luke, Peter etc could shed some light on this.

They obviously should know/name a part by just looking at it?

rev 2 and rev 3 have different booster design

hence the stopper bolt is too short for rev 3,

i have both booster

rev 3 is bigger but flater
rev 2 one is thicker but smaller in diameter

No, that's not right. The only *rev* change is rev1 to rev2. However they seem to be different depending on the market the car was sold in.

FYI, I have a new from Toyota master cylinder and booster, ordered from my frame number (rev3 turbo) and the stopper fits fine.

Hi All

can I re-kindle this thread for my own issues with a Tegiwa brace I ordered from their Ebay site, ( http://www.ebay.co.uk/itm/172307419569? ... EBIDX%3AIT )

As you can see from the link I made sure it was a non ABS equipped brace as
my Rev3 Turbo doesn't have ABS. However when fitting from images supplied
in this thread. It doesn't seem to fit correctly.

The first issue is the bolt that you remove from the black cylinder centre
and then replace once the brace is mounted, its now not long enough to
engage any thread and just spins, now of course this is rectifiable with a
longer bolt, however the brace seems to sit away from the cylinder and isn't
flush, causing more issues.



Secondly as you can see from these image's the brace when put together
is awkward and out of line, meaning the bolt that braces the MC has to be
forced through the MC brace arm that is bolted to the tub, subsequently
its also way to short and also doesnt aline to where its supposed to meet the
MC, and finally the MC I have, has a recess but doesnt have any type of female
thread to mate with the MC brace bolt ?



Finally, any ideas what these are for ?



Thanks Guys.

red one looks like it goes on end of bolt to save the bolt digging into master cylinder, blue one is countersunk so goes on other end of the bolt.

But looks like you need to buy a longer bolt anyways.

Ah yes, now you say it it makes sense that the red piece is used to push against the MC ,
I will have to get 2 new bolts as both are too short, but it still does't fit exactly right but I'm sure once its tightened up it would be an issue ?

The bolt on mine that presses against the BMC is a lot longer than that. I would also thread a nut and washer onto the long bolt to lock the 2 blue arms together.

Hi Mate

Yeah thats a good idea, I don't know why they haven't thought
of that and supplied in the kit tbh !

thanks for the tip, ill have to get a couple of longer bolts and try re-fitting
the kit.

[JLW]

Messaged TEGIWA and they are sending me longer bolts for both the BMC
and the MC brace , will get a couple of nuts and a washer to lock the arms together also.
