A vehicle will not be drivable without brakes which function properly. If your braking system were to ever malfunction, it could probably be attributed to a brake fluid leak. There are four places in the braking system where a leak could take place. There could be one in the brake master cylinder, the front brake caliper, the brake line, or the rear brake caliper. Regardless of where the leak is coming from, the symptoms of the leak will surely be recognizable.
Top 5 Symptoms
Below are the 5 main symptoms that you can expect when you have a brake fluid leak.
- Warning Light – The first symptom that you should notice is the brake warning light on your dashboard turning on. You may not even feel any serious brake problems at this point. But if you see the warning light on, this is an early indication that something is wrong with your brakes and that you should have them looked at right away.
- Strange Brake Pedal Feel – The brake lines should only have brake fluid inside of them. If there is a brake fluid leak and air gets mixed with the fluid in the brake lines, then the fluid will not be able to flow correctly. As a result, when you press your foot down on the brake pedal, it will feel squishy or spongy. In other words, the brake pedal will feel very soft.
- Brake Pedal Too Far Down – This problem relates to number 2 on this list. If air continues to get inside your brake lines while there is a leak, then it will bring airborne contaminants into the braking system. Furthermore, condensation will begin to form which will eventually cause the brake pedal to move all the way down when you press on it. After you fix the leak, you need to “bleed the brakes” and replace all the old braking fluid with new fluid.
- Visible Fluid Coming Out – If you see fluid leaking from underneath your vehicle and you’ve experienced one of the first three symptoms already, then you definitely have a brake fluid leak. You should immediately get your car to a mechanic to have this leak fixed because the more fluid that comes out, the less fluid you’ll have in your braking system.
- Car Does Not Stop– The worst possible symptom will surely be noticeable. You should not get to this point without experiencing the previous symptoms first. But if you have ignored those symptoms, then expect your brakes to eventually fail altogether. Then, you will end up driving your car without being able to stop. This, of course, will result in a car accident which could leave you with body damage and vehicle damage.
The cost to repair a brake fluid leak will depend on where the leak is coming from. As previously mentioned, there are four main locations in the braking system where fluid could be leaking from. Most of the time, you can repair these locations without having to actually replace the part altogether. If replacement is required, then you are looking at parts and labor costs. With just a repair job, the cost of labor and parts are pretty evenly matched out. In total, you should expect to pay between $100 and $300 for a brake fluid leak repair job.
If there is a leak in the brake master cylinder, then you can expect to pay an average of around $100 to $200 for the parts and $100 for the labor. If there is a leak in the brake line or the front brake caliper (one side), it is also between $100 and $200 for the parts and $100 for the labor. The cheapest repair job is if there’s a leak in the rear drum cylinder or rear brake caliper. This will be around $80 in labor and $20 in parts, totaling $100.
