Abstract

1418630 Internal shoe drum brakes; fluid pressure braking systems AUTOMOTIVE PRODUCTS Ltd 6 Dec 1972 [16 Dec 1971] 56348/72 Divided out of 1418628 Headings F2E and F2F Brake shoes 19, 20 are expanded by hydraulic pistons fed from master cylinder 100, or by a spring-operated mechanical wedge 26A which is normally lifted by compressed air from reservoir 93 which also energizes the master cylinder. Other subject-matter is similar to that disclosed in the parent Specification 1,418,628.
