Technician A says a low fluid level in the reservoir may indicate worn brake pads. Technician B says a small geyser of brake fluid from only one master cylinder reservoir chamber when the brake pedal is applied may indicate abnormal cup wear. Who is correct?

Question

Quizplus · Accepted Answer

Both technicians are correct. A low fluid level in the reservoir can indicate worn brake pads as the pads wear, the calipers extend further and the brake fluid level in the reservoir drops. A small geyser of fluid from only one master cylinder reservoir chamber when the brake pedal is applied indicates abnormal cup wear, as fluid is being forced past the old, worn cups instead of being directed to the calipers.
