| (sheet 3) (10) The brake carrier plates require proper forgings. At the moment they are rather solid heavy lumps of metal. We understand that experiments have been made to show that the hand brake will neither tighten itself on or release itself when left on for the drums and shoes to cool down after the car has been run. It has however been said that the hand brake mechanism requires a little more spring, or possibly a finer ratchet to facilitate engagement of the catch. We understand it is proposed to slightly increase the proportion of front braking compared with the present standard. I shall be glad to know if you are in agreement with the above, and that these alterations should be made to bring the system up to production standard. We have examined the brake shoe mechanism itself and this appears to be quite satisfactory. We understand that this relies for its lubrication on the use of Keenol which only requires replenishment when the brakes are overhauled, that is, re-lined. E.{Mr Elliott - Chief Engineer} | ||
