The invention is related to a brake shoe with a chamfered edge lining, the chamfered edge achieving desired surface configuration of the lining after only a few braking actions while increasing the service life of the lining. The chamfer has a profile shape which features a hyperbolic contour, steeply angled at the top adjacent the outer face and very shallowly angled at the bottom adjacent the backing plate so that the increment of wear of each braking operation decreases in a strongly degressive way.

Brake pad for disc brakes

A simple-design device for the measurement of coefficients of friction depending on the relative speed between a sample (8) and a brake disc (13) features a simple-design set-up and is well suited for the measurement of the changes of the coefficient of friction in the starting and in the stopping phases of the friction surface (13). The device operates by pressing the sample (8) with a defined pressing force (K1, K2) onto the friction surface (13) and simultaneously measures that force (K3) with which the samples (8) are dragged by the friction surface (13) transversely to the pressing force (K1, K2) as a function of time and speed. A brake disc can be provided as a friction surface (13). A single source of forces (K1, K2) for the pressing force can also be provided, resulting in a simple-design and sturdy structure for the device.

Inwardly straddling disc brake for automotive vehicles

An improved disc brake which avoids brake noises. Mass is added to one or both of the brake housing and the brake carrier to preclude the natural frequencies of several components from coinciding, thereby preventing noise in that resonant frequency.

Disc brake

A spot-type disc brake, in particular for motor vehicles, comprises a brake housing enclosing the rim of a brake disc and further comprising brake pads arranged on both sides of the brake disc and still further comprising at least one piston-cylinder-type actuating device. In order to reduce the influence of the heat generated during braking, the brake housing is formed with at least one ventilation channel arranged close to the brake disc beside a brake pad shaft which accommodates the brake pads.
