Just Updating with some New Info.

You can buy a suitable, brand-new pilot-operated Tractor-Trailer Brake Valve from GES Hydraulics of Crowland, Peterborough ( and it can be supplied with either nitrile or viton seals to suit tractor master-slave brake systems which run on either mineral oil or brake fluid. Only drawback is that it isn't cheap (~£300).

Thanks for sharing your findings with the rest of us. I might have to look into it myself as we run a 285 and 2100 on 10ton trailers braked on the spool valve, been like it for last 20years and once you get a feel not bad to use. But if the valve your on about is £300 I don't think that's a bad price for more user friendly operation.

Might be cheaper than you think. Having a proper system fitted would go a long way to reducing the number of "get outs" available to your insurance company,as well as putting you in better standing with officialdom.

I don't think that price is too bad - if you're doing much road work it's got to be well worth it to have a safe, automatic system that's legal.
