External Conditions That Affect Brake Performance

TIRES
Tires having unequal contact and grip on the road will cause unequal braking. Tires must be equally inflated, identical in size, and the tread pattern for both the right and left sides should be approximately equal.

VEHICLE LOADING
A heavily loaded vehicle requires more braking effort. When a vehicle has unequal loading, the most heavily loaded wheels require more braking power than others.

WHEEL ALIGNMENT
Misalignment of the wheels can cause the brakes to pull to one side.
