NOTES

BRAKE DUST The efficiency of motor car brakes can often be improved by a thorough cleaning of the brake shoes and the inside of the drums, at least twice a year. Brakes that have an inspection opening can be cleaned by inserting an air hose, or if this is not, available, a good tyre pump, into the opening and blowing out the accumulated dilAf On other types of brakes it will be necessary to remove the drums. r l he. dirt that accumulates in the drums consists of fine particles of brake lining material, road dust that has worked its way in»past the covering plates, and some fine metallic particles that have been worn off the brake drums. This accumulation of “brake dust,” as it is usually called, collects in the operating part and between the lining and drum, where it affects the braking action. This dust will absorb oils and moisture, with the result that the effective coefficient of friction is altered, and consequently tlie brakes aro liable to giip or slip.

CAR OF THE FUTURE The automobile of to-morrow will be shaped like a tear-drop, probably controlled by one lever, and will save motorists millions annually on their petrol bills because of its reduced wind resistance, Sir Dcnniston Burney, designer of the RIOO, in Toronto for tlie National Motor Show, told tlie Canadian Club.
