About Brake Servo Units

The brake servo unit, if fitted, is an aid to the hydraulic braking system. With the operation of the servo unit less force is required on the brake pedal.

The servo unit is situated in the braking system and has a connecting rod that runs between the brake pedal, the master cylinder and fluid reservoir and is commonly found in the engine compartment.

The Chevrolet brake servo unit is a bulbous cylinder which contains a central diaphragm. On each side of the diaphragm there are two separate chambers The cylinder has a vacuum feed from the engine manifold this maintains a vacuum in both chambers. When the brake pedal is pressed an influx of external air is sucked into one side of the diaphragm, the air pressure rises as the vacuum is broken which pushes the diaphragm to assist the movement of the master cylinder which forces the hydraulic fluid through the piping to the slave cylinders on the brakes of each wheel. When the footbrake is released the vacuum is restored to the chamber.

Signs that there's a problem with the Chevrolet brake servo unit can be that the pedal becomes heavy and requires increased force to operate the brakes. 

Chevrolet trivia

• The company might have his name, but Louis Chevrolet wasn't there for long. He'd previously worked as a mechanic for other car manufacturers, and would eventually go onto become a well-established race car driver for Buick.
• The first Chevrolet was a bit of a disaster. Nobody wanted to buy the car, probably because the price was higher than other, similar vehicles. It was only when Louis Chevrolet left that the company started to turn things around.
• The first Chevrolet was the iconic series C Classic Six. It sold for the very low price of just $2,150. That's about £1700 in proper money.
• The weirdest Chevrolet experiment was the Chevrolet Turbo Titan II in 1965. This was the same year as the first US spacewalk, and the car has a real space theme happening. Most bizarrely, it didn't have a steering wheel and instead had two large dials so that it looked more like a games console controller or DJ desk than a car.
• When it comes to innovation, it's hard to get angry at Chevrolet for being the first company to install 4G wifi in its cars.
