Symptoms of a bad master cylinder include leaking fluid, fading pedal and bad brake fluid. When the brake pedal starts to sink, becomes unresponsive or feels spongy, the master cylinder is malfunctioning. A bad master cylinder does not transfer the power from the brake pedal to stop the vehicle safely.Know More
Symptoms of a bad master cylinder include external and internal leaks. When brake fluid is leaking from the seals, the driver should notice a leak at the back of the master cylinder bore. In some cases, a leak near the vacuum booster or inside the vehicle shows signs of a bad master cylinder.
When a vehicle is turned off, the brake pedal should remain firm. However, if the driver pushes the pedal lightly and it sinks to the floor, the master cylinder has an internal leak. If the brake pedal is fully depressed and feels unresponsive or spongy, this is the result of a malfunctioning master cylinder.
Another symptom of a bad master cylinder is bad or contaminated brake fluid. Noticing brake fluid in the reservoir that contains water or dark-colored fluid displays a problem with the master cylinder. This type of contaminated brake fluid can cause rubber seals in the cylinder to deteriorate, which leads to the leak. Stuck ABS valves and calipers are another symptom of a bad master cylinder.Learn more about Brakes
Symptoms of a cracked cylinder head are identical to those of a blown head gasket and include engine misfires, leaking oil that drains from the engine and the seemingly unexplained presence of coolant fluid in engine oil. Cracks in a vehicle's cylinder head may be large enough to see or may be invisible to the naked eye, and diagnosis of this issue as opposed to issues with similar symptoms, such as a blown head gasket, requires specific techniques including the use of dye and pressure to expose the cracks. Because it can be easily confused with other issues, diagnosing a cracked cylinder head requires more than simple knowledge of symptoms.Full Answer >

Motor vehicles with low brake fluid require a mechanical inspection to avoid experiencing a brake system failure. Low brake fluid typically means that a vehicle's brake pads are wearing thin or that there is a leak in the brake line system. Neglecting to address low brake fluid is bound to lead to potentially unsafe and expensive problems.Full Answer >
