Can ABS system cause soft brake pedal?
A hydraulic assembly, or ABS modulator, is used in vehicles with anti-lock braking systems (ABS). Multiple solenoids and valves are contained within this assembly. A low or spongy pedal can be caused by an internal failure, corrosion, or debris in the brake fluid.
What would cause my brake pedal to suddenly go to the floor?
In the majority of cases, a problem with the fluid in your brakes is to blame. You’ll have a spongy brake pedal if your brake fluid level is low or if air gets into the brake line. Another common reason for a broken pedal is a faulty brake booster.

What would be the cause of a dropping brake pedal with no fluid loss from the system?
Internal leakage in the brake master cylinder is the most likely cause of a sinking pedal with no external leakage. The brake fluid may boil due to moisture contamination or friction material gassing if the brakes are hot.

What is the most common problem with ABS systems?
Sensor contamination with debris or metal shavings is the most common cause of ABS failures. Sensor wiring can also be damaged, resulting in intermittent or non-existent continuity, which can lead to malfunctions.
How can you tell if your ABS module is bad?
ABS module failures can cause brake pedal insensitivity in some vehicles. This varies from model to model. Brakes that don’t work or don’t work in a safe manner are a clear problem, as an unresponsive pedal won’t stop the vehicle. Most of the time, this will take place gradually, over a long period of time.
