Renault Braking System Fault [Meaning & Solution]

‘Braking System Fault’ dashboard error messages are a sign that there is something wrong with your Renault.

This article will provide a comprehensive explanation of this specific error, its causes, and possible solutions based on extensive Renault experience.

Renault Braking System Fault [Meaning & Solution]

Renault Braking System Fault: Explanation

You should be notified by your Renault ECU if your vehicle’s braking system is experiencing any issues.

Your car’s engine and transmission are controlled by the ECU, which is basically the brain of the car. It controls the engine and transmission as well as many other systems that keep it running.

Renault Braking System Fault Explanation

A malfunctioning component will cause the ECU to display an error message on its screen if it detects it.

There are many parts to your Renault’s braking system, including brake pads, discs, calipers, ABS, and master cylinders among others. A “braking system fault” will appear if one of these is malfunctioning.

Common Signs of Braking System Fault

Common Signs of Braking System Fault

Braking noises

Odd noises during braking are one of the first signs of a Renault car’s braking system malfunction. Brake pads that squeak, grind, or sound metallic may indicate worn-out brakes.

Dashboard warning lights

Onboard diagnostics are standard on modern Renault vehicles. It is important not to ignore warning lights associated with the brake system. A potential fault is indicated by these indicators and needs to be addressed immediately.

Braking delay

When the brake pedal is pressed and the vehicle doesn’t respond immediately, a braking system problem could be underlying. The brake calipers or brake fluid levels may be causing this delay.

Causes of Braking System Faults in Renault Cars

As a result of my experience working with Renault vehicles, let’s investigate the most common causes.

Causes of Braking System Faults in Renault Cars

ABS sensor failure

As the name implies, an ABS prevents wheels from locking up while they are braking, also called a wheel speed sensor (on older cars).

The car can pull to one side or another when you brake when the ABS sensor fails. Over time, these will fail, and an error message will appear stating “Braking system fault.”.

Brake fluid low

In order for your brakes to work properly, you need brake fluid. A Renault with low or dirty brake fluid will display a “Brake system fault” message. Ensure your brake fluid is always at the right level by checking it regularly and topping it up if necessary.

Disconnected or failed brake pad sensor

In Renaults, a brake pad sensor that fails or becomes disconnected is the most common cause of a braking system fault.

In the event that your Renault brakes or rotors have recently been replaced, but they have not been secured properly, this can occur.

This will cause the ECU to think that the system is not under pressure when the sensor reads zero.

It is possible, however, for another brake sensor in your vehicle to fail simultaneously, causing other dashboard error codes.

Worn Brake Pads

Wearing brake pads is easier to spot, so this is an obvious and straightforward method. You slow down when you contact the brake disc with your brake pads.

Your dashboard can display a “Brake system fault” message if your brake pads are worn out and cannot make good contact with the wheel surface. You need to change your Renault’s brake pads if any of the following apply:

  • Applying the brakes produces a grinding or squeaking noise
  • Applying the brakes causes a pulsing sensation
  • It feels spongy and soft when you press the brake pedal.
  • It looks like the pads are thin.

Low voltage or a bad battery

A constant flow of power is needed by your Renault’s computer to control the braking system. You may receive a “Brake system fault” message on your dashboard if your battery is old and cannot provide enough voltage.

The brake rotors (discs) are damaged

Friction between the brake discs and the braking system helps your brakes work.

Damaged brake discs cannot provide good contact with the surface of your wheels, causing your braking system to malfunction.

How to fix this Fault on a Renault

My personal recommendations for fixing your Renault brake system fault are as follows:

How to fix this Fault on a Renault
  • Make sure your car’s brake fluid levels are adequate. Check to see if the message goes away if it is low. If it is low, top it off and turn off the vehicle.
  • The battery voltage should be checked; if it’s low, it should be charged or changed; also, ensure that the battery is disconnected and reconnected properly.
  • You should check your brake pads and rotors if the message still appears after following steps 1 and 2. Have them replaced if they are in poor condition.
  • Check the brake lights as well to make sure they are functioning properly.
  • Getting your car diagnosed by a Renault dealer or mechanic is a good idea if you did all four steps and still have the problem.
