A fast-fill valve in a master cylinder acts as the inlet port and the compensating port. fitted between the reservoir and the cylinder bore. It is a combination valve with a ball and a pressure seal. Depending on the pressure, it allows flid to flow from the large bore of the cylinder to the reservoir, or from the reservoir into the large bore.

. If you have the 4-port master cylinder, the bottom ports go to the rear brakes & the upper side ports go to the front brakes.
If a pressure type brake fluid dispenser is available attach it to the top of the master cylinder. Other wise fill the master cylinder, start with the wheel cylinder that is furthermost from the master, and bleed until fluid comes out clean and free from bubbles. make sure to replenish the the master cylinder as needed. then proceed to the next farther wheel cylinder and repeat with the rest of the wheel cylinders. top off the master cylinder. Test with the engine off then with the engine running before driving.
the master cylinder is designed so that when the brakes are applied, the pistons (primary and secondary) closes the compensating port and opens intake port. this allows brake pressure to be formed in brake system to apply brakes and allows brake fluid to fill behind pistons (through intake ports) when you release the brakes, the primary and secondary piston springs push their pistons (inside the master cylinder) to its rest position, faster than fluid can fill the chambers. this causes the brake fluid to flow past the piston cups (this happens when the rubber cup flexes foward) as the pistons pass the compensating port, brake fluid is allowed to return to the master cylinder reservoir. the intake and compensating ports act as a breather for the master cylinder. hope this answers your queston :)
The low side charging port is located high up, near the firewall, on the driver's side, right by the brake master cylinder.
Located next to the break master cylinder on the drivers side. in the engine compartment.
Type your answer here... Correct Answer: Allow for the normal expansion and contraction of brake fluid due to temperature changes
The easiest way would be to use a suction device that is specifically designed for bleeding the brake system. Attach the vacuum hose to one of the wheel cylinder bleed ports, make certain that the master cylinder reservoir remains full of fluid, then pull fluid from the wheel bleed port. It is recommended that you repeat the process for each wheel.
