Title:
IMPROVED DRUM BRAKE PAD
Document Type and Number:
WIPO Patent Application WO2006110320
Kind Code:
A8
Abstract:
An improved drum brake pad for drum brakes includes a drum brake having a drum including an outer generally cylindrical circumferential wall having an inner braking surface and a side wall plate mounted thereon and a braking mechanism including at least one brake shoe having an arcuate brake pad mounted thereon and brake actuating means operative to force the arcuate brake pad into frictional contact with the drum. At least two diagonal grooves are formed in the arcuate brake pad having a generally V-shaped or U-shaped cross-sectional shape and extending across the entire width of the arcuate brake pad, the diagonal grooves removing the liquid within the drum brake when the arcuate brake pad engages the drum wall to force the liquid rearwards and outwards out of the drum within the diagonal grooves due to the rotation of the drum relative to the arcuate brake pad.
