Arkana spongy brake pedal
Summary of the thread
A 2021 Renault Arkana hybrid owner is experiencing a spongy brake pedal and consistently low brake fluid levels, suspecting worn brake pads as the cause. Another owner with a similar issue suggests checking for leaks around the master cylinder or brake lines, as it could be more than just worn pads. The issue was resolved by replacing worn brake pads and rotors and addressing a slight leak in a rear caliper, highlighting the importance of professional inspection for complex hybrid systems.

Thanks for the quick reply. I haven't spotted any visible leaks, but I haven't done a thorough inspection of the master cylinder. When you had the spongy pedal, did the brake fluid level drop noticeably?

Yeah, the fluid definitely went down over time. I topped it off once, but it kept happening. Eventually, I took it in, and they found a slight leak in one of the rear calipers, plus the pads were pretty worn. Honestly, with the hybrid system, I'd just have a shop take a look. It's a complex system.

Appreciate the insight. I'll book a brake inspection. It's probably best to have a professional diagnose it properly. I ended up replacing the brake pads and rotors and got a fluid replacement, which set me back 480€. Thanks again!

Whoa, that sounds familiar! I've got an Arkana too, and I had a similar issue with the brake pedal feel. Did you check for any leaks around the master cylinder or brake lines? That's the first thing I'd be looking at. It could be more than just worn pads.
