More braking effort is applied to the front brakes because?
The front axle carries more weight than the rear normally
Of weight transfer during braking
The fact that they are closer to the brake master cylinder
Front brake are better cooled due to being at the front
Pitch, when applied to vehicle suspension, is defined as.
