Purpose of using A12-28714-000:

  • Increases braking power – Uses hydraulic pressure to multiply the driver's pedal force.
  • Reduces pedal effort – Makes it easier to press the brake pedal.
  • Improves braking response – Helps the braking system generate pressure quickly.
  • Provides consistent braking assistance – Maintains power assistance during normal driving conditions.
  • Supports heavy-duty braking – Particularly useful in trucks and other vehicles requiring greater braking force.
  • Works with the master cylinder – Transfers the boosted force to the master cylinder to produce hydraulic brake pressure.
  • Improves driver control – Allows strong braking without requiring excessive physical force.


Signs of a Bad Hydraulic Brake Booster A12-28714-000:

  • Hard brake pedal – The pedal requires significantly more effort than normal.
  • Reduced braking assistance – Braking feels weak even when the pedal is pressed firmly.
  • Longer stopping distance – The vehicle takes more distance to stop than usual.
  • Brake pedal feels inconsistent – Pedal effort or feel changes unexpectedly.
  • Hydraulic fluid leaks – Fluid may leak around the booster, hoses, or connections.
  • Whining or unusual noises – The hydraulic system or power-steering pump may make abnormal noises when braking.
  • Brake pedal pulsation or vibration – The pedal may shake or feel uneven during braking.
  • Low hydraulic pressure – Insufficient system pressure can cause poor brake assist.
  • Power-steering problems – On Hydro-Boost systems that share the power-steering circuit, steering may also become unusually difficult.
  • Brake warning light – A warning light may appear if the vehicle detects a brake-system or hydraulic-pressure problem.
