Question

Quizplus · Accepted Answer

Internal rubber parts in a master cylinder can wear with age and compromise its sealing ability, causing leaks. Clogged ports are more likely to cause restrictions in the brake fluid flow, leading to a loss of pressure or a spongy brake pedal feel. However, it is possible that a leaky master cylinder can have clogged ports as well.
