Braking System Fault Renault

What does braking system fault mean?

If you see a “Braking system fault” warning, it means there could be a problem with your brakes. This warning pops up on your dashboard to let you know that something might be off with one or more parts of your braking system.

The problem could be low brake fluid, worn-out brake pads, a wonky brake sensor, trouble with the brake light switch, or some other glitch in your braking setup.

How to Fix Braking System Fault Renault?

What does braking system fault mean

While we’ve talked about four potential reasons for this warning light, in reality, 99% of the time, it’s the fluid level causing the problem. So, my strong recommendation is to check the fluid level first before diving into any other solutions.

1. Low Fluid Level

The most common reasons behind the “braking system fault” in your Renault often tie back to the brake fluid level. If there’s a strainer in the reservoir’s neck, it might lead to confusion about the real brake fluid level.

Keep an eye on the handbrake switch, even though it’s generally dependable. Another key point to remember is that worn-out brake pads can cause a drop in the brake fluid level, triggering the occasional fault.

Here’s a straightforward fix to tackle brake fluid issues. Start by topping up the brake fluid and keeping a close eye on the level.

If you notice a significant drop, like around 5mm in a week, it’s time to look for leaks.

Don’t rush into replacing sensors; sometimes, the problem is simpler. Check if worn-out brake pads are causing the fluid level to go down.

Top up the brake fluid and inspect the brake pads. When looking at the rear brakes, don’t forget to check the inside pad.

Remember, the brake and clutch share the same reservoir, so wear, fluid level, and warning signals might be connected. Keep it simple and cover all the basics.

2. Low/Damaged Battery Condition

The likely reason for the “braking system fault” in your Renault is the starter not engaging.

When the system acts like it’s in ECO mode, it often points to a low battery. This low battery can activate the ECO mode, messing with the starter and resulting in the braking system fault.

Here’s what you can do to fix this.

Start by disconnecting the negative battery cable and leave it that way for about a minute. Then, reconnect the cable.

Once you’ve confirmed the battery is good to go, try starting your car. This trick is all about resetting the system and getting rid of the ECO mode caused by a low battery, which might just sort out that braking system issue.

But if you found that the battery is too old and weak or damaged then replace the battery asap.

3. Sticking Brake Light Switch

This one is very rare for “braking system fault” in your Renault. To confirm this, see if your brake lights stay on constantly, as it’s a sign of a possible sticking switch.

A stuck brake light switch might interfere with the normal operation of the braking system and could also affect the functioning of cruise control, as the system thinks the brakes are in use.

To solve this, just check and, if needed, replace the brake light switch.

If you notice the brake lights staying on, look for the brake light switch under the glove box, accessible from the floor without a lot of disassembly.

If the switch seems stuck, it’s best to replace it. This should get your brake lights working correctly and help sort out the occasional brake system issue.

4. Corrosion on Rear Brake Sensor

This is the final reason for the “braking system fault” in the Renault. The corrosion on the rear brake sensor, starts from the disc. The corrosion on the sensor probably messes with how it should work, causing the braking system fault.

If you face a corrosion issue on your rear brake sensor, Check and clean the sensor to get rid of any corrosion it might have picked up from contact with the disc.

Also, make sure the disc is in good shape without too much corrosion. Doing these steps should help get your rear brake sensor working properly again and get rid of the brake system issue linked to corrosion.

It’s a good idea to do regular checks and maintenance to avoid facing this problem again.
