Hydrocephalus is due to a problem with the flow of the fluid that surrounds the brain. This fluid is called the cerebrospinal fluid, or CSF. The fluid surrounds the brain and spinal cord and helps cushion the brain. CSF normally moves through the brain and the spinal cord and is soaked into the bloodstream. The flow of CSF is blocked.
The Tesla Model S has a collision avoidance assist system that automatically engages the brakes to reduce the impact of a frontal collision. Automatic emergency braking will stop applying the brakes when the driver presses the accelerator pedal, the brake pedal, or sharply turns the steering wheel.
The brakes on the 1984-87 Pontiac Fieros are four wheel disk. They utilize a solid, unvented rotor and have a set of rear calipers that can be actuated mechanically as well as hydraulically. The mechanical actuation is used for the emergency brake. Pontiac redesigned the Fiero brakes in their last year, 1988. This upgrade is NOT for the 1988 model year cars. The stock 1984-87 brakes will safely stop the car, but for performance and safety oriented Fiero owners, they leave a lot to be desired. Several methods of improving the brakes are available.
