Seat Leon Brake Fluid Level Low
Summary of the thread
The initial concern was a low brake fluid level and an odd brake pedal feel in a 2015 Seat Leon. Possible causes included worn brakes or a failing master cylinder. It was suggested to check for visible leaks and consider worn brake pads as a likely reason for the fluid drop. A soft pedal could also indicate air in the system or internal issues with the master cylinder. The recommended solution was a thorough brake inspection by a technician, who confirmed worn brakes as the issue, leading to the replacement of brake pads, rotors, and brake fluid.

Thanks for the quick response! By strange feedback I mean the brake pedal feels kind of soft and I have to push it further down than usual to get the car to stop. I haven't noticed any obvious leaks, but I also don't really know what I'm looking for around the master cylinder. What should I be checking for specifically?

Okay, a soft brake pedal that requires more travel definitely points to air in the system or a failing master cylinder. Since you haven't spotted any leaks, and you mentioned the low fluid level, worn brakes are the most probable cause. However, don't rule out the master cylinder entirely. If the internal seals are going bad, it could cause the soft pedal and gradual fluid loss without an external leak. Given your description, I'd strongly recommend a thorough brake inspection by a qualified technician. They can check the pad thickness, rotor condition, and the master cylinder for any signs of internal leakage. A brake fluid replacement might also be a good idea, as old fluid can absorb moisture and affect braking performance.

I wanted to let you know, I took the Leon to a local mechanic and they confirmed your suspicion. Worn brakes were indeed the culprit, causing the brake fluid level to drop. They've replaced the brake pads and rotors, and also performed a fluid replacement. The total cost came to around 480€. Thanks so much for your help, I really appreciate it!

A soft or strange brake pedal feel combined with a low brake fluid level on your 2015 Seat Leon is concerning. Firstly, never drive with low brake fluid. Have you checked for any visible leaks around the calipers, brake lines, or the master cylinder itself? If the fluid is actually disappearing, it's going somewhere. Worn brake pads can cause the fluid level to drop as the caliper piston extends further to compensate for the thinner pads, but it shouldn't be a drastic drop. What do you mean by strange feedback? Is it spongy, hard to press, or something else?
