    It's a ferguson, therefore, the best advice re brakes, for the owner of any Ferguson, is never tow an unbraked heavy trailer - they won't take the strain, they dissolve/break up and contaminate the oil, leading to hydraulic pump failure and a big bill. . Same goes for any oil immersed braked tractor.

    On the specifics of fixing 4235 brakes, someone else will have specifics, but on the towing warning - heed it, or you'll have a big bill. You'll notice an above average number of queries here on MF brakes...

    We did the brakes on a 3080 there a week or two back - again, it was towing an unbraked low-loader - that was the cause - the symptoms were poor brakes and intermittent non-functioning steering/lift etc. Basically, because the brakes share a home with the hydraulic oil, when your brake lining gets stripped through over-stress, they contaminate the oil which then effes the pumps. The cure, new brakes, pumps, filters etc is neither quick nor cheap. A braked trailer makes a lot of sense..another early symptom is claggy solenoids under the cab - again, brake residue queering the pitch. And there's two pumps.. The symptoms only kick off when the oil is warm btw - might all function grand when cool - but a pressure gauge on the pump output after a good fast drive to warm the oil will tell a different story - pressures will be way down and problems evident.

    I must admit first off of being biased as i never liked 3080 anyway thought they were some office designer's idea of a new tractor to replace 300 series. cab with electrics and a body with 399 type engine fired in,some changed gearbox's to sort them,etc. the 300 series are ok towing loads across fields, as one would describe normal farm-work with routine complete servicing .
    excessive low loader and dumper work without proper service, destroys all rear ends ,power shifts, brakes ets. and there are loads of tractors still in storage for sale after dumper work during celtic tiger construction era,nearly every site had diggers & dumpers hauled by tractors with teenagers driving the living daylights out of them and no servicing just trade and buy new, i know of tractors around 100hp less than 18 months old purchased in excess of €30k that failed simple shuttle type change from forward to reverse the first time used for agitating ,slurry spreading and one in particular that was moving round bales off field. and rear-ends told story when opened and none of those were ferguson, not makers fault i stress just the treatment by first owner.
