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 Peugeot 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 Peugeot brake servo unit can be that the pedal becomes heavy and requires increased force to operate the brakes. 

Peugeot trivia

• It's a dubious claim to fame, but the first recorded stolen car was a Peugeot! The car, belonging to Baron de Zuylen, was nicked by his mechanic in 1896, but the thief was caught, and the car returned to its rightful owner.
• Peugeots have been seen on the big and small screen. Most notable, the Peugeot 403 convertible was the car of everyone's famous scruffy detective Colombo. There was also an episode of Absolutely Fabulous where Edina and Patsy drive through France in a 205.
• Lots of car manufacturers tried building electric vehicles at some point, but Peugeot had more success than others in the 1940s! Fuel restrictions promoted the design, and the car came with four 12-volt batteries that meant a range of 80km on a single charge and a top speed of 32km/h.
• In 1913, one of Peugeot's motorsports team, Jules Goux, not only won the Indianapolis 500 but also broke the World Speed Record. He was the first European to win the Indy 500, and the 7.6-litre car was dubbed the fastest vehicle of the time.
• The first diesel engine prototype from Peugeot was built in the 1930s, but they didn't start releasing models commercially until 1959 (the 403).
