Abstract
Abstract A brake comprises an elongate friction pad engageable with a rotor surface, the friction pad being supported close to the rotor surface by a support. A connecting link connects the support to a fixed structure and transmits the braking drag forces to the fixed structure whilst permitting a degree of substantially friction-free movement of the body of friction material toward and away from the rotor surface.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
133 words
A brake for braking a rotor having a braking surface, comprising an elongate body of friction material for braking engagement with said rotor surface; a support close to said rotor surface supporting said body of friction material; a fixed structure; connecting means connecting said support to said fixed structure; and means for urging said body of friction material into engagement with said rotor surface, wherein said connecting means comprises at least one flexible member which is relatively rigid in a first plane perpendicular to the direction of movement of said body of friction material and which is flexible in a plane perpendicular to said first plane, said flexible member comprising a plate including means defining an elongate slot which permits said flexing, said member being connected between said support and said fixed structure.
Claim 2
Dependent Claim
133 words
A brake for braking a rotor having a braking surface, comprising an elongate body of friction material for braking engagement with said rotor surface; a support close to said rotor surface supporting said body of friction material; a fixed structure; connecting means connecting said support to said fixed structure; and means for urging said body of friction material into engagement with said rotor surface, wherein said connecting means comprises at least one flexible member which is relatively rigid in a first plane perpendicular to the direction of movement of said body of friction material and which is flexible in a plane perpendicular to said first plane, said flexible member comprising a plate including means defining an elongate slot which permits said flexing, said member being connected between said support and said fixed structure.
