Limiting friction is the maximum value of static friction which operates when a body is just going to start sliding over the surface of another body. It depends upon the nature of the surface but independent of the area of surface, provided the normal reaction remains unaltered.

The limiting friction between two surfaces refers to the maximum amount of friction that can be generated when an object is on the verge of slipping or sliding. The factors that affect the limiting friction are:
a) Nature of the surfaces:
The nature or type of surfaces in contact does not affect the limiting friction. It means that whether the surfaces are rough or smooth, the maximum amount of friction that can be generated remains the same.
b) Normal reaction:
The limiting friction is directly proportional to the normal reaction between the two surfaces. The normal reaction is the force exerted by a surface perpendicular to the contact surface. As the normal reaction increases, the limiting friction also increases, and vice versa.
c) Weight of the body:
The weight of the body does affect the limiting friction. The limiting friction is directly proportional to the weight of the body. As the weight of the body increases, the limiting friction also increases. This is because the weight of the body increases the normal reaction, which in turn increases the limiting friction.
d) Volume of the body:
The volume of the body does not affect the limiting friction. The limiting friction depends on the normal reaction, which is determined by the weight of the body and not its volume. The volume of the body does not play a role in determining the maximum amount of friction that can be generated.
In summary, the limiting friction between two surfaces depends on the normal reaction and the weight of the body. It does not depend on the nature of the surfaces or the volume of the body.
