.... an allen bolt fitting inside. Very solid when it's all bolted together.

I just used an Indian switch housing and took some of the ali out from inside until it slid over the headset. Its the right shape switch housing. :) it did take a while to get it to fit properly though.

I also started off with a remote master in the horn cover but as you, I found it was utter pants.

I was due to go on track but if I had done with the remote master I would have defo gone off at the first braking zone lol.
They work but just no where near as well as you may be used to. 1st time I went out with mine I over shot the first junction I got to just because it didn't work as well as expected so be careful 1st time out with it.

I've bought an inboard hydraulic too, and I'm starting to worry if it'll even be as good my reverse pull drum.

I can see me investing in an outboard disc and handlebar mounted remote about a fortnight after putting it on the road.

I have an inboard hydraulic with remote cylinder under the horncasting and I love it. It gives me 1 finger braking and has perfect 'feel', without being snatchy or grabby. As such, don't be too quick to write such a setup off!

That may be the case but I hate hydraulics when they lack feel and become an ON/OFF affair. My inboard is an old DJ that I ran for a while on my cutdown, with bar mounted master cylinder, and it was a bit too ON/OFF for my liking. Rebuilding it with a hidden master cylinder actually benefited the performance and it is now a pleasure to use.

I used to service my Dad's PX disc and the front brake on that (stock factory) was NASTY!

I never really saw the need for a hydraulic front disc on a Lambretta until I started using the Indian 200 casings, which give such poor rear brake action that I've seriously changed my mind!

Adam

PS - I've seen 46 or 47mph!

It's taken me a while with several projects on the go at the same time but I went for the bracket option.

Sorry it's a bit late for this but here's my Spanish S2 switch housing. It's a grimeca master cylinder welded to the Spanish housing (with trapezoid switch) by Mark Broadhurst and the caliper is also one of his old school outboards

Hi all,

I'm looking to fit another hidden system, having enjoyed the function of the first one so much, and wonder if you guys/gals have figured out where the cheapest outlet is for the Grimeca remote cylinders is? I've have a quick look online but note that there is considerable range in price. Any ideas on who is cheapest for new?

Thanks in advance.

Adam

PS - I'll be looking to use one of the Chas-speed brackets (shown earlier in this thread) so need to keep to the Grimeca item, rather than change to Nissin or any other.

I’ve got a couple from bike breakers, I think they are widely used on twist & go’s.

Have a look at the Oiltek hidden master cylinder Adam, they bolt under the legshields into existing holes on the front support cross bars. Very neat set up and you can put the reservoir almost anywhere for easy access to it.
