What are the common faults and main causes of automotive braking systems

The brakes are weak or malfunctioning

Brake fluid problem: Brake fluid leaks, is insufficient, or deteriorates and absorbs water, causing hydraulic pressure to not be established and pedal travel to become longer.

Friction wear: Excessive thinning of brake pads, reduced friction area, and significant decrease in braking force.

Assist system malfunction: The vacuum assist pump of the fuel vehicle is damaged or the vacuum tube is detached, causing the pedal to become abnormally hard; Abnormal electronic assistance in new energy vehicles can also lead to sudden changes in foot sensation.

Brake deviation or shaking

Unilateral braking force abnormality: The wear degree of the left and right wheel brakes is different or the cylinder is stuck, causing the vehicle to tilt to one side when braking.

Brake disc deformation: The surface of the brake disc is uneven or excessively worn, causing significant shaking of the steering wheel and body during high-speed braking.

Tire pressure difference: Inconsistent tire pressure between the left and right tires can exacerbate brake deviation, and it is necessary to maintain normal tire pressure.

Brake noise or overheating

Material and component issues: The brake pad material is too hard, the muffler is detached, or the brake hose is aging, resulting in sharp noise during friction.

Thermal decay phenomenon: Continuous heavy braking or long downhill driving can cause excessive friction temperature, a sharp decrease in friction coefficient, and a decline in braking force.

Driving habits influence: Intense driving or prolonged driving on high friction roads can accelerate the wear and aging of brake system components.
