What Causes the Brakes to Suddenly Become Hard and Unable to Depress?
1 Answers
Sudden hardening of the brakes is generally caused by issues with the brake booster pump, foreign objects adhering to the brake pads and calipers, or the intervention of the vehicle's ABS system. Below is relevant information: 1. Problems with the brake booster pump: If the brakes suddenly become hard while driving, it may be due to a leak or blockage in the vacuum tube of the brake booster pump. In such cases, it is necessary to stop the vehicle immediately for inspection and replace the part if required. 2. Related to braking before engine shutdown: The vehicle's braking system operates most effectively when the engine is running, with the brake booster pump playing a crucial role in amplifying the force applied to the brake pedal.
