Some car issues immediately demand attention, such as squealing brakes or unusual engine noises. Brake fluid is however not easily noticed. It silently does its job until the day when you step on the pedal and notice that something is not working as it should, it does not stop as quickly as before. It is then that the question comes in; how do I check brake fluid?
It is a legitimate question, and a significant question. The silent so-called hero of the braking mechanism of your car is Brake fluid.
This blog describes what to do to test your brake fluid in a proper way and when it is better to leave the task to the professionals such as the experts of the SAI Auto Care of Perth that work with the brake system and inspect it in their everyday tasks.
Why Brake Fluid Even Matters
Think of brake fluid like the messenger between your foot and your car’s stopping power. When you press the pedal, brake fluid pushes that pressure through the lines and tells the brakes to grab the wheels.
If the fluid level drops too low, or if it’s old and full of gunk, your brakes won’t respond properly. The pedal might feel soft, or worse sink right to the floor. That’s why a simple brake fluid level check now and then is worth your time.

How Do I Check Brake Fluid — Step by Step
You don’t need fancy tools. Just a good light, some tissue, and steady hands. Here’s how:
Step 1: Park the Car and Let It Cool
- Start simple: park on flat ground, switch off the engine, and let things cool for a few minutes.
- Don’t open a hot bonnet right after driving; that’s just asking for burns.
- Pull the handbrake, pop the hood, and take a breath.
Step 2: Find the Brake Fluid Reservoir
- Look toward the back of your engine bay, near the driver’s side.
- You’ll see a small plastic container semi-transparent labeled Brake Fluid or DOT 3 / DOT 4.
- That’s your target. If you’re unsure, check the owner’s manual. Every car hides it somewhere slightly different.
Step 3: Check the Level
- Now, don’t open the lid just yet. Look from the side, you’ll see “MIN” and “MAX” lines on the container.
- The brake fluid should be somewhere between those marks. If it’s sitting below “MIN,” you’re running low. Time for a brake oil check or refill.
- If it’s been low more than once, that could mean there’s a leak in your system, best to get a mechanical inspection done at a proper workshop like SAI Auto Care.
Step 4: See What It Looks Like
- Fluid level is only half the story. The condition matters just as much. Fresh brake fluid is clear or light golden. Over time, it turns darker, brownish, murky, even black. That’s when dirt, rust, and moisture have gotten in.
- If it looks like that, it’s time for a brake fluid replacement. Some people use a brake fluid test strip, which checks for water content. You can grab one from an auto shop if you want to be extra sure.
Step 5: Add Brake Fluid (If Needed)
- If you do need to top up, wipe the area around the cap clean; no dust or grease should fall in. Then open it carefully.
- Check your car’s manual for the correct type (DOT 3, DOT 4, or DOT 5). Don’t mix them, mixing can mess with your brake pressure and cause bigger issues.
- Pour slowly until the fluid sits just under “MAX.” Tighten the cap again.
Step 6: Keep an Eye Out Afterwards
- If your fluid was low and you topped it up, keep checking for a few days. If it drops again or your pedal still feels soft, that’s not normal.
- That’s your clue to visit brake specialists in Perth or call a car mechanic in Perth who knows how to trace leaks and air in the lines.
- And if your car doesn’t feel safe to drive, call a tow truck service Perth, better that than risk it. SAI Auto Care even helps coordinate towing if needed.

How Often Should You Check Brake Fluid?
Honestly? Every few months is a good habit. It only takes a minute once you know where to look.
Most car makers recommend changing it every two years or roughly 40,000 km. But in Perth’s heat or with stop-start driving, it might need attention sooner.
When to Leave it to the Professionals
There’s a difference between checking brake fluid and changing it. Changing it (also called a brake flush) needs tools and experience because air bubbles or dirty fluid lines can completely ruin your braking system.
That’s where auto brake repair experts like SAI Auto Care come in. They don’t just change the fluid they inspect the full braking system: pads, rotors, master cylinder, and lines. It’s part of their regular car brakes service, which keeps your whole setup healthy, not just the fluid.
Final Thoughts
It is not a difficult task to check on the level of your brake fluid, it is one of those few things which keep your car safe and reliable.
Do it once in a while and when something does not seem/feel okay, then do not worry about it, call somebody who knows what is going on. Here is SAI Auto Care, one of the best auto care services provider in Perth which is doing brake services, auto repairs, and fluid checks daily.
