What Causes Soft Brakes and Ineffective Braking?

[SanCarter]

Soft brakes and ineffective braking may be due to leakage in the wheel cylinder. The owner can first check if the wheel cylinder is leaking and then bleed the air from the system. For air brake systems, insufficient pressure requires inspecting the pipelines and air pressure pump. If the brake clearance is too large, adjust the brake pad gap. Conduct a systematic inspection of the air brake system, including the brake control mechanism, dual-circuit brake mechanism, central disc brake mechanism, brake assembly, and air compressor. The reasons for soft brakes and ineffective braking include the following: 1. Air in the brake lines: Brake fluid is the medium for the braking system. If air enters the lines, the brake fluid under high pressure will lack sufficient strength, resulting in noticeable weakening of maximum braking force despite the presence of braking power. 2. Long overdue brake fluid replacement: If brake fluid is not replaced in time, it may contain excessive impurities and moisture, affecting the transmission of braking force. 3. Oil leakage or overly soft brake materials: Typically, leakage in the master cylinder or brake lines can cause softening of the vehicle's brakes. If the brake materials are too soft, their high-temperature stability will also deteriorate, leading to softer brakes.
