Abstract
The invention relates to internal-external shoe drum brakes, or so-called 'crown' brakes in which the braking member is a drum or crown having braking surfaces formed on the annular inner and outer surfaces. The brake is provided with a calliper mounted on a fixed bracket, the calliper surrounding the crown and being adapted to apply brake shoes mounted on either side of the crown against the braking surfaces. The calliper is mounted on the fixed bracket for radial movement with respect to the crown and to this end is provided with at least one transverse lug formed with an aperture which slidably engages a guide pin mounted on the fixed bracket. The guide lug is formed separately from the calliper and is detachably secured thereto so that it can be released from the calliper when it is desired to change the brake shoes.
