8-97078045-0 Brake Sub-Cylinder Piston Rear for ISUZU 700P works as follows:
Hydraulic drive: when the driver depresses the brake pedal, the piston inside the brake master cylinder is pushed and squeezes the brake fluid out of the outlet of the master cylinder and presses the hydraulic fluid to the brake sub-compact through the brake fluid pipe .
Piston movement: the piston in the brake sub-pump starts to move under the pressure of hydraulic fluid.
Push the brake pads: the movement of the piston pushes the brake pads closer to the brake disk, so that the brake pads and brake disk close contact.
Generate friction: the close contact between the brake pads and the brake disc generates friction, which gradually reduces the rotational speed of the brake disc, thus realizing the deceleration or stopping of the vehicle.
Return process: when the driver releases the brake pedal, the piston in the brake master cylinder returns, the outlet port closes and the inlet port opens. At this time, the hydraulic oil in the brake sub-pump in the brake disc rotation under the action of centrifugal force, as well as the action of the brake sub-pump piston return spring, through the brake pipe back to the brake master cylinder, the brake sub-pump piston is also returned to the brake pads and discs separated, the vehicle to return to the normal driving state.
