A brake fluid pressure sensor is used in anti-lock braking system (ABS). ABS fault lights come on with unexpected wheel lock from the ABS system, but could also include low fluid in the reservoir. ABS fault lights come on with unexpected wheel lock from the ABS system, but could also include low fluid in the reservoir.
The pump in the ABS is used to restore the pressure to the hydraulic brakes after the valves have released it. A signal from the controller will release the valve at the detection of wheel slip. After a valve releases the pressure supplied from the user, the pump is used to restore the desired amount of pressure to the braking system.
Specialised pumps may incorporate a method to automatically keep the brake fluid reservoir full during bleeding. In the reverse method, a pump is used to force fluid through the bleeder valve to the master cylinder. This method uses the concept that air rises in liquid and naturally wants to escape up and out of the brake system.
The Sensotronic Brake Control (SBC) system operates using a hydraulic high-pressure reservoir to supply brake fluid. A piston pump, driven by an electric motor, generates controlled brake fluid pressure ranging between 140 bars (2,000 psi) and 160 bars (2,300 psi) in the gas diaphragm reservoir. [2]
Retrobright (stylized as retr0bright or Retrobrite [1]) is a hydrogen peroxide-based process for removing yellowing from ABS plastics. Yellowing in ABS plastic occurs when it is exposed to UV light or excessive heat, which causes photo-oxidation of polymers that breaks polymer chains and causes the plastic to yellow and become brittle.
