Squeaking brake mechanisms, attributing the fault to over-lubrication of the guide pins.

| -2- I do not feel that the fault is entirely on post-war cars, but it has always been a general one. Apart from the above we have also complained of squeaking of this brake mechanism, which, as previously reported, is due to the guide pins for the brake shoes, and in order to overcome this trouble we feel that the brakes will be lubricated as above referred to, i.e. too much oil will get on to the brake shoes, causing the brakes to be ineffective owing to the surfaces becoming lubricated, whereas the squeak is not cured. Please let me know whether any improvement in the present construction can be considered in regard to the above, and what temporary alterations, if any, can be made on cars about which we receive complaints of squeaking, seizing up of the brake shaft or ineffectiveness of the brakes due to overoiling, and we suggest the work should be charged to R.D.D. order number.
