ABSTRACT:
A brake shoe having a metallic support or backbone member with a brake pad formed of at least two portions, each of a separate compound or composition, with each compound pre-selected to effect a separate result for each of the pad portions. The portions are configured, arranged and dimensioned so that each (and all) pad portions have a braking surface in contact with the rim generally simultaneously. The partitioned brake pad is formed of different combinations of multi-rubber or elastomers, not a particular combination, to improve wet and dry braking with one pad or the same pad. The selection of multi-rubber or elastomers could be used to stop squealing and grabbing, while also giving the pad stopping power at the same time; or a different combination could be used in wet and dry conditions, or a combination of compounds may be utilized for different partitions for racing conditions, or the like.
