Making these up soon.

Saves you having to drill more holes into your firewall. Not sure if that's an appealing enough feature but I hate drilling holes where you don't really need them.

I'd be interested in one of these adapters.

Also, if someone can measure the width (or height) of the master cylinder flanges on the non-1200 masters, I can see if they would fit the Patrol clutch booster as I have a Patrol here!

the height is the same as a 1200 master cylinder for all the tokico master cylinders

Yeah thought so Chris that is cool will take one as I have a sunny booster here. Unless I'm the only one keen then and you need a bulk buy. Then may have to just make a similar one myself when the time comes. Pretty sure i wont need a booster with a stocko A12.

Yeah im pretty sure they are rolled threads, havent had a look at one for a while

have you checked the brackets with a sunny booster for fitment into a 1200?

DD, both have a pair of short horizontal studs and long verticle studs coming out the front

both run a spacer between the master and booster that bolts onto the horizontal studs then the booster bolts onto the verticle studs

Pretty sure sunny booster has short studs. Also if the studs were welded in you could just get the thread tapped right down and cut them down to desired length.

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
Yeah brilliant idea keen to know more e.g thickness of steel used and price. The photgraphed one is the one PIGDOG made I'm pretty sure.

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
This idea is most brilliant.
I take it the spacing offset from the firewall will be the same as the thickness of the B210/610/510sss aluminium spacer bracker?
Is there a thread pertaining to the EOI for these? Since they're going to make a booster set up "bolt on" for any 1200, they'd have to be the best thing since the S13 caliper adapter bracket.
Even though I'm very serously consider selling the 1200, I'm also quite curious about the cost etc for one of these.

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
Hey Bart, hope things are going okay over your way.

Yes these are the thickness of the alloy mount that you typically see between the master and firewall.

The EOI hasn't gone up yet but the 1000 lads know about this as I mentioned these on datsun1000.com. I'll get a thread up soon.

At the moment these will probably be stainless steel or alloy along with a cheaper mild steel option. I am unsure of the costs at the moment but will know when I get it on the way.

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
Things are going as well as can be expected. (okay, but not great)

I think made from 3mm mild steel, from laser cut plates, and TIG welded together. And then zinc plated in silver or gold could almost look like a factory part. Plus the addition of a booster would easliy enable the fitemnt of a larger MC, without making the pedal too heavy.

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
Hey thanks for that dd, yeah that one does the job but my design is to be a bolt up assembly for my 1000, that picture you showed has the studs welded to the flange that meets the firewall.

I don't know how you are supposed to screw them into the threads into the firewall?

Who made that one? did it work?

Bart, I am going for the mild steel electroplated style, the stainless and ally is kinda for the option really...after-all it's only a bracket.

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
Sure does come with the long studs. But can you remove them and replace with shorter manifold studs? or use short bolts?

Yep.

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
Hey Tommo,

I'm not sure I have one here with short studs and a 120y one with the long studs, I tried to remove them but they're quite tight. I think the studs will have to be cut shorter and then tapped.

Unless I have a Sunny one which Andy reckons are the short stud. Either way the brackets are going ahead, I might leave it up to the individuals to solve that issue.

EDIT: You're spot on Andy, here is a pic of one:

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
yeah thats my one pictures with a sunny booster, slightly larger than a 120y one...probably more than slightly

neither 120y or 180b have short studs and you wont be able to tap more thread on from memory as the studs go undersized, the only small booster than would have short studs is the nissan patrol or gtr skyline clutch booster which i dont think anyone has used yet but looks to be a 120y style one and the master cylinder mounts look the right spacing

mine has fixed studs as that was easier than having a bolt and a nut, as all you have to do on a 1200 is knock the standard master cylinder studs out and then you have nice holes to put those studs on the bracket through

you do have to enlarge the hole in the firewall though so that the booster pushrod can fit through as its pretty big and i wanted the boster to be as close to the firewall as possible

works great and was only somthing i knocked up in a half a day out of a master cylinder spacer a bit of plate adn a bit of pipe to get the booster in there. still needed to knock a bit of a dent in the strut tower in a 1200 for it to be able to get it in and out though

currently have an r33 master cylinder on my sunny booster to match the brakes

EDIT: was running a 7/8th master unboosted before this with 4 piston front and single piston disc rear. wasnt too bad till i went to the larger 4 piston front and twin piston rears. so anything smaller should be fine without a booster really

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
This is mine in the car, as you can see in a 1200 if it was any further forward you would have about 0% chance of getting it in there. as its actually quite a bit larger than the 120y one. bit still smallish

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
Thats interesting. So the threads are rolled onto the 120Y/180B studs, leaving them with a smaller diameter that the OD of an M8 thread?
Perhaps they could be threaded 5/16 instead?

 Re: 120y Master Cylinder Upgrade Brake Booster Adapter
If there is something made to go under the dash of the 1000
so I can hide the master cylinder like Tommo has Id be in.
Then you can run an external booster like that on valiants.
