How does the presence of oil on brake pads affect the performance and safety of a vehicle?

The presence of oil on brake pads can reduce friction between the pads and the rotors, leading to decreased braking performance and potentially compromising the safety of the vehicle. Oil on brake pads can cause the brakes to be less effective in stopping the vehicle quickly and efficiently, increasing the risk of accidents. Regular maintenance and inspection of brake systems are important to ensure optimal performance and safety on the road.
