Brake Law Amendment for Light Vehicles.
An Amendment Order dated October 14th and concerning the brakes on motorcars weighing under two tons, has been issued by the Ministry of Transport. It provides that where fourwheel brakes are fitted, it is unnecessary that there should be two entirely independent systems, but that there must be two independent means for operation; one must operate brakes on all four wheels, whilst the second may operate them either on all four or on two wheels only.
The Order also provides that a motorcar shell be so designed that on the failure of any single portion of any braking system the driver shall be able to apply brakes to two of the wheels. Where one of the means for operation acts through hydraulic, electric or pneumatic devices the other means must apply the brakes by direct mechanical action. One set must also be capable of being left in the " on" position.
Only Complete Report of the Motor Show.
Those who would like a complete record of the Olympia Motor Show should get the big Third Show Number of The Motor, which is now on sale. It contains the only report in one issue covering every exhibit after personal examination, and it is illustrated by many hundreds of special drawings and photographs. This year the report is divided into 12 sections, each alphabetically arranged for the convenience of readers.
Included in it is a coloured plate of an exclusive drawing by Bryan de Grineau, depicting Kaye Don's new car, with which he will attempt to break the world's speed record next year.
The Jackson Reconstructed Dennis.
We regret that our article concerning the .Jackson reconstructed Dennis may have been somewhat misleading. We referred to it as a six-tonner and we are informed by Dennis Bros., Ltd., that there are, actually, no .6-ton Dennis parts used in its manufacture. The frame has strengthening plates added, and both the front and rear axles were designed for a vehicle carrying 31-ton loatisoThe engine is of the 1919 series, and it cannot rightly be called a Dennis because it is equipped with Watson cylinder blocks. The road-wheel bearings are of the old type with floating bushes, which have been discarded for some time by Dennis Bros., Ltd. An old-type gearbox is employed, this being brought partly upto-date by the addition of certain new components. The Dennis-standard axle ratio for the subsidy model was 7.75 to 1, and where a different ratio is utilized gearing other than that of Dennis make is employed.
In conclusion, we would point out that we have always been strongly against overloading and we would certainly not recommend users to impose much more than n tons on the axles built for a vehicle of this capacity.

A.E.C.-F.W.D. Working Arrangement.
Dating from October 15th a working arrangement has been made between the Associated Equipment Co., Ltd., and the Four Wheel Drive Lorry Co., Ltd., which also includes Hardy Bail Motors, Ltd.
The principal units in the construction of F.W.D. and Hardy products will be of A.E.0 make.
In addition to the standard four and six-wheel-drive chassis there is an F.W.D. low-loader of six tons capacity driving through the front wheels, which are equipped with 36-in. by 8-in, pneumatic tyres. The loading platform is 2 ft. 3 ins, from the ground.
The F.W.D. commercial tractor has a 7-ft. wheelbase, a four-cylindered engine of 65 b.h.p. and a seven-speed gearbox. It is capable of hauling loads up to 20 tons on trailers, and has 36-in. by 8-in, pneumatic tyres on the four driving wheels. The road speed is 26 m.p.h. at normal engine revolutions.
There are three models of six-wheeler, a four-cylinder of six tons capacity, a six-cylinder to carry eight tons and a six-wheel-drive tractor with a drawbar pull of 12,000 lb. and a powerful winch.
Then there are half-track machines. and in the Hardy range a standard shunting locomotive to basil 230 tolls on the level, tower wagons, inspection coaches, etc.
Owing to the four-wheel drive many of these vehicles have been selected for use with special equipment, such as fire pumps, cranes, grabbing machines, etc., and other equipment which the Associated Equipment Co., Ltd., considers will be of great interest to many of its dealers and customers. All A.E.C. branches will be in a position to supply complete information regarding these chassis and equipment. Some of the latter can be incorporated in the A.E.C. chassis, and the company welcomes this arrangement, which it hopes will lead to the farther ,enlargement of its programme.
Brake Alterations to B.A.T. Cruiser.
We learn that the recently introduced B.A.T. Cruiser chassis will be continued for 1930 in its present form, but certain alterations have been made to the foot-operated brakes. The pedal actuates a variable-leverage mechanism which, in turn, is coupled to a pair of master cylinders for the hydraulic brakes. One cylinder controls the brakes on the front axle and the other those on the rear axle.
First Registrations During July.
In goods vehicles, 5,271 new machines were registered in July this year, as compared with 3,388 in July, 1928.
In the caption below the Albion vehicle used by J. Lyons and Co., Ltd., and published in our issue dated October 15th, we referred to this as a 3(lcwt. lorry, whereas it should have been referred to as a three-tonner.
