Brake independent of adhesion

Brakes that are independent of the adhesion value are brakes on railways and rail vehicles which, in terms of their braking force, are independent of the frictional connection between wheel and rail. Common brakes independent of adhesion are:

• Magnetic rail brakes
• Eddy current brakes
• Gear brakes
• Caliper brakes on brake rails
• Dog brakes , formerly of trams used

In a broader sense, brakes that are independent of the adhesion value include:

• Brake screens
• Thrust reversers
