External Conditions That Affect Brake Performance

Tires
Tires that have unequal contact and grip on the road will cause unequal braking. Tires must meet the following conditions:
- Equal inflation
- Identical size
- Equal tread patterns for both the right and the left sides

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.
