1. Farmers, growers, processors and industry representatives are being asked for their views from 31 August for 10 weeks on the role of the Agriculture and Horticulture Development Board (AHDB).

    The AHDB is a UK statutory levy board, funded by farmers, growers and others in the supply chain. As we leave the EU, there is an opportunity to ensure that the sectors that the AHDB covers are as competitive as possible. This review will look at the AHDB’s purpose and priorities, its strengths and where improvements need to be made.

    This is a joint 10-week exercise covering England, Scotland, Wales and Northern Ireland. The request for views will close on 9 November.

    Hi, wonder if any one can explain the basics of the brake system on a 1989 - 1 ton - benford dumper, this has ST1 Lister diesel engine, at the moment there is a brake master cylinder behind seat, running from this is 1 copper line which goes into top of front axle, the other side is not connected at all, how does the brakes work through the axle, i read some where they are immersed in oil, can any body help ? thanks

    Ive messed with oil brakes on a 4t benford

    Copper pipe to either side of the axles large wet brake disc . With half shaft thru middle . Looks like a clutch disc
    Oil presumably from axle / diff
    Large rubber o ring was seal i think .
    It was a few years ago .

    hi tomlad thanks for reply, basically theres only 1 copper pipe connected to front axle, so no brakes at all, hopefully it would just be a case of connecting up second pipe and bleeding systyem, but ive no idea how the brakes operate, theres another short brake pipe on the axle which does a small loop onto 2 different brake nipples and disapears into the axle on each one ive looked at some photos of other axles and this seems to look correct, so i will try and connect all up and see what happens, i will let you know, cheers, (might be gone for some time)

    Rear axle of the one i mentioned
    I think both same axle

    Oil in on side fitting . Out on top fitting to other side (same axle ) in on side / 3 o'clock blead screw on top .
    If that makes sense. Looks like one copper pipe to each axle . In one side across to other . One blead per axle .
