Causes of brake pedal hardening

 

* Damage to the brake assist hose

The brake assist hose connected to the "servo" must be checked regularly, as damage to this hose or its movement from its place leads to hardening of the brake pedal, which leads to accidents

* Damage to the servo

The servo has an important function in the car as it helps reduce the effort resulting from pressing the brakes, and when the servo is damaged, the brake pedal is exposed to hardening, so when it is damaged, it must be changed quickly

* Fluid leakage

Brake fluid leakage leads to a loss of pressure inside the brakes, which leads to the pedal hardening, but at a low level as the pedal starts very soft until it ends at the bottom hardened and the brake effect is often very weak and the car is unable to stop

* Accumulation of dirt and sediments

Sediments can accumulate in different parts of the brake system, and their effect on the pedal hardening varies according to the presence of these sediments

* Malfunction of the hydraulic valves

The brake system has parts that control the distribution of hydraulic pressure force on the wheels, in order to maintain the balance of the car, and these parts are often found in the anti-lock system ABS, and if these valves are damaged, a malfunction occurs in the hydraulic pressure, which leads to the pedal becoming stuck

* Pedal damage

The pedal itself may be exposed to mechanical damage in its movement outside the hydraulic system, such as the presence of an object that prevents it from moving normally or damage to the pedal spring or mounting screws

* Brake fluid shortage

When the brake fluid is low, the pedal will become stuck and you will notice weak brakes due to the lack of brake fluid, which prevents the brakes from working properly.
