| Notes of Meeting - 4 Sg{Arthur F. Sidgreaves - MD}21/H21.12.34 - 4 - the front shock absorber loading automatically increases and is considerably more than 105 lbs. (as referred to above) when the car is travelling at the speed at which the tramp is likely to occur. The Design Dept. are, however, dealing with the question of moving the axle control out or some such device to overcome this trouble entirely, and it is hoped that, if it is not possible to get this on 5-B-IV before it goes away, it may be possible to send it out there for test whilst the car is there. It is understood that 5-B-IV is fitted with radius rods which help. 2. Jaggers when coming to rest with the linings wet; Ferodo bonded asbestos is said to be slightly better than M.R.material but is not a cure. We are fitting this plus water excluders to Rippon's car which is now in the Experimental Dept., i.e. trying all we know on this car and the results will be reported. If of worth while benefit the information will be circulated to depots to enable them to deal with complaints. Future cars. There is a water excluder more efficient than anything we have previously tried which will be tested on 5-B-IV. (3). Jaggers when brakes are applied sharply at 40 m.p.h. or below. This is not known as a bad complaint from customers. It can frequently be reduced by increasing the swinging arm load and Service Stations are to be advised of this. As regards future cars, as it usually occurs at the end of a high speed tramp, this means that, if we cure the latter, we shall deal with the former. 4. Front Brake Thumps. This is also susceptible to adjustment of the swinging arm and to a lesser extent to | ||
