Braking System Fault In Renault [Causes, Fixes & Solution]

An error warning light showing “braking system fault” indicates a critical issue within the brake system that can also affect the stop and slow-down efficiency of the vehicle. Are you facing this problem in your Renault’s megane three or any other model?

I will guide you in fixing this error by following some easy and quick steps. We will also know the possible causes affecting brake systems and the solutions to solve this error. So, follow the comprehensive details breakdown in the below paragraphs.

What is the braking system fault in the Renault?

The brake system in Renault is complex, consisting of many components like brake pads, master cylinders, brake lines, calipers, rotors, and an anti-lock braking system (ABS).

The safety of the vehicle and its occupants depends upon these parts. When any of these components are malfunctioning, faulty, failed, or damaged, it can lead to a severe accident and cause a dangerous situation. 

It underlines the urgency and importance of addressing any fault with braking system. However, it is impossible to drive vehicles conveniently without a well-maintained and proper braking system. The most common faults that happen in the braking system are as below:

• ABS warning light
• Brake fade
• Brake noise
• Brake pulling
• Brake fluid level
• Master cylinder
• Spongy brake padel
• Vibrations during braking

Most of the time, any of the abovementioned faults are found in braking system.

How to fix the braking system fault in Renault?

When any fault is detected in the braking system, the electrical control unit (ECU), the engine’s brain, will pick it up and flash an error on your vehicle’s dashboard. However, fishing the brake fault issue is tricky; you must follow the guidelines in the videos below.

Possible causes of braking system fault

Here are all the common possible causes that can be the reason for brake faults; check each of them because knowing about these is necessary:

• Low brake fluids
• The brake pad fault
• Brake rotors fault
• Corrosion of components
• Temperature extremes
• Lack of regular service
• Heavy loads
• Aggressive driving
• Low-Quality components
• Weak or low-voltage battery

Low Brake Fluids

The first and most common cause that refers to warning of braking system issue is low brake fluid levels. Brake fluid contamination, leakage, and depletion badly affect the brake system. Sometimes, low-quality fluids have less longevity than high-quality brake fluids.

Best and manufacturer-suggested fluids improve the brake’s efficiency for extended time intervals.

The Brake Pad Fault

The primary function of brake pads is to reduce friction from metal to metal, which lies between the rotor and caliper. Over time, the brake pads must be replaced because it will start reducing the brake performance and increasing the stopping distances when the brake is applied.

Brake Rotors Fault

Whenever you hit the brake pedal, the brake pad clamps down on the rotor to stop the car safely and smoothly. Over time, rotors naturally wear due to high-temperature effects and friction that can trigger the warning of braking system faults in Renault vehicles.

Corrosion Of Components

The brake’s components are affected by moisture over long intervals of years will lead to corrosion. The brake parts like pads, calipers, and rotors will continuously lose effectiveness and usability with time, leading to severe damage and accidents. 

Temperature Extremes

When you apply the brake in a high-temperature season, overheating and degraded components will create a pulsating sensation, reducing the stopping power of brake parts.

Lack Of Regular Service

The braking system’s regular and routine maintenance service keeps it in good condition. Skipping or forgetting any regular service will show signs of wear on various parts that need replacement or repair.

Due to irregular or skipped service, fluid contamination and depletion will majorly impact other brake system parts.

Heavy Loads

When you consistently start putting heavy loads on your Renault, it will place an additional stress on the braking system, resulting in losing the friction between parts. 

Aggressive Driving

Sometimes, bad driving habits like aggressive driving or driving in an emergency frequently hard braking affect the power of hydraulic systems parts.  

Low-Quality Components

Improperly designed brake parts, faulty ABS sensors, low-quality brake rotors, calipers, and pads of poor quality can trigger the warning message of braking system problem in Renault cars.

Weak Or Low-Voltage Battery

A low voltage, old, and damaged battery is another significant cause of brake fault errors. If you’re using a battery as old as 3 to 4 years, it is likely not delivering enough voltage to the brake sensors like ABS. 

Solutions to braking system fault

After determining the causes of brake faults next step is to solve it ASAP. I will explain all the solutions to common causes comprehensively.

1. Regular maintenance
2. Battery inspection
3. Brake fluid levels top-up
4. Load management
5. Addressing the symptoms promptly
6. Smooth braking
7. OBD-II scanner

Regular Maintenance

Focus on regular and routine maintenance of your Renault car from a certified technician with deep knowledge of using advanced equipment and replacing or repairing brake components. However, if it is needed to change or repair any part, ensure to do it to prevent other severe damage.

Battery Inspection

Inspect the battery condition regularly and check whether it needs to be changed or charged. Also, disconnect and reconnect the battery correctly before starting the engine on.

A battery is a significant part of controlling any vehicle’s electrical system. So, only use high-quality and mechanic-suggested batteries for safe and longevity rides. 

Brake fluid levels top-up

Check brake fluid levels regularly; top it up if the level is low. Don’t over use the contaminant or dirty fluid oil and replace it with a new high-quality crude.

Load Management

You must understand load management and learn how much load you can put in the vehicle. It will prevent additional pressure on the braking components and avoid faults in braking system. 

Addressing the symptoms promptly

When you hear loud noises, vibrations in the braking system, or a warning light indicating an error, immediately consult a mechanic or diagnose it yourself. It will prevent you from facing a significant loss or multiple braking parts replacement.

Smooth Braking

If you’re using the vehicle brakes smoothly and nicely, it will sustain for a long time without triggering any issue or critical error. To avoid abrupt stops, keep the proper distance from other vehicles, which will minimize the need for hard braking.

OBD-II Scanner

Diagnosing the internal problems of vehicles with the error codes scanning tool, OBD-II will help to detect pinpoint issues with the casing parts. It will also show all the code errors and descriptions in a few minutes.

In conclusion, factors like low fluid, damaged or faulty brake parts such as rotors, calipers, pads, aggressive driving, irregular service, heavy loads, and weak battery trigger the warning light of braking system faults. Firstly, inspect the pinpoint and identify the part that needs attention.

Still, I recommend taking your car to the nearest Renault mechanic shop if you cannot solve the issue.
