Patent ID: 7114600

Claim:
A brake device for a motor vehicle having a first friction element including a lining with a first face that is pressed against a first face of a second element that is secured to a wheel of the motor vehicle in order to slow down the vehicle and an application third element having a piston with a first end through which a braking force is applied to a second face on a rigid support of the first friction element to effect a brake application, said brake device being characterized by amplifer means having a first part that is connected to the first end of said piston and a second part that is connected to the second face of the rigid support, said first part of said amplifer means having a first plane face that is parallel to and in mutual abutment with a second plane face on said second part through a bearing surface, such that in response to the braking force being applied to said piston, the first part and the second part of the amplifier means pivot about a tiltable plane that is initially substantially parallel with the first face of the second element to modify the application of the braking force through the rigid support in effecting a brake application.
