CHANGES have been made by Ford to the braking system of all D Series goods models so that these meet in full the regulations effective for new vehicles on January 11968.
The improved braking systems result in some price increases but to compensate for this Ford has increased its rated gross weights —by up to 1.25 tons on the biggest tractive unit—and in many cases high-capacity tyres are now fitted as standard. The increased chassis cost ranges from 115 for the D300 to £105 for the short-wheelbase D750 and D800.
Except for the D200 and D300 models all D Series chassis now have air-assisted handbrakes through an additional diaphragm chamber acting on the mechanical linkage. On all chassis, actuation is by a single-pull umbrellatype handle mounted on the dash.
The D200 and 1)300 retain their servicebrake systems but have Clayton Dewandre light-laden valves to adjust the driving axle braking according to the load being carried. The 13400 also now has a light-laden valve at the rear axle but the air/hydraulic brake system previously standard on diesel-engine chassis only is now standard on all.
The same type of air/hydraulic system is also standard on all D500. D550, D600. D700 and D750 models while on the D800 the air/ hydraulic dual-line system continues as standard.
In the tipper categories. 9ft. wheelbase models have light-laden valves and D600, D700 and D800 tractive units have the air/hydraulic dual-line system as standard with the addition of an auxiliary line for semi-trailer connection and a light-laden valve at the driving axle.
Six-wheel DT800 chassis now have a dual-line air/hydraulic system with a number of improvements.
