What Causes the Hissing Sound When Braking After Replacing Brake Fluid?
1 Answers
After replacing the brake fluid, the hissing sound when braking occurs because the brake pads have worn thin, causing the backing plate to grind against the brake disc, or due to hard brake pads (poor quality) or foreign objects in the brake pads. Other situations can also arise when braking. Brake Pedal Rebound: Brake pedal rebound is most commonly experienced by drivers who brake aggressively. When the ABS system activates during hard braking, the brake pedal may rebound, which does not happen during normal braking. Aside from this normal phenomenon, faults such as uneven brake disc or pad surfaces or deformed wheel rims can also cause this issue. Brake Pulling: Brake pulling, or uneven braking, occurs when the steering wheel noticeably pulls to one side during braking, indicating uneven braking force distribution between the wheels. This fault is relatively rare but can lead to serious accidents if it occurs. The primary causes are uneven brake pad wear or issues with the brake caliper. Immediate inspection at a repair shop is necessary if this occurs.
