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

Renault trivia

• Renault has more models of electric cars than any other manufacturer, with the Twizy, Kangoo, and Fluence their most popular electric-powered vehicles.
• The Renault RS01 was dubbed ‘the yellow steam engine’ after it became the world’s first-ever turbocharged F1 car. It wasn’t a reliable car, but it was certainly quick!
• The Royal family have always enjoyed a Renault, but the first royal sale was in 1905 when King Edward VII bagged himself a Landaulette. Our current monarch didn’t pay for one; however, they did receive a Renault Dauphine as a gift in 1957.
• Back in ‘96, Renault got a previously unheard of 4-star rating in the EuroNCAP crash test, designed to maximise passenger safety. At the time, this was the highest award that had ever been granted by the board.
• The aluminium-bodied Renault Spider was essentially a race car that had been built for the road. Models sold everywhere, but it was only those that were sold in the UK that came with windscreens, which must have meant a lot of bugs in the face for French drivers.
