Ducato Brake Fluid Loss
Summary of the thread
A 2002 Fiat Ducato was experiencing consistent brake fluid loss and a spongy brake pedal. The potential causes discussed included worn brake pads, which could cause the fluid level to drop, and possible leaks in the brake lines or master cylinder. The suggested solution was to replace the brake pads and inspect for leaks, followed by bleeding the brake system to remove any trapped air. Ultimately, the vehicle was taken to a garage where worn brake pads and a leaky brake line were identified and repaired, resolving the issue.

Yeah, I had a quick look around the wheels, didn't see any obvious puddles or anything. Brake lines look... okay-ish? Hard to tell, really. Master cylinder, no idea where to even start looking for that! So, if it is just the pads, would replacing them sort the fluid loss and the spongy pedal, or could there be something else going on even if the pads are worn?

Even with worn pads, the spongy pedal suggests air might have entered the hydraulic brake system due to the low fluid level. Replacing the pads is a good first step and definitely needed at that mileage, but you'll likely also need a fluid replacement to bleed the system and remove any trapped air. Honestly, considering it's your brakes we're talking about, and you're not completely confident in identifying leaks and bleeding brakes, I'd highly recommend taking it to a workshop for a proper brake inspection. It's like trying to fix your own heart – best left to the pros!

Okay, that makes sense. Didn't want to mess with the brakes too much myself if it could be something serious. Dropped it off at the garage this morning. Turns out it WAS worn brake pads, but also a slightly leaky brake line. Got them replaced, system bled, and she's stopping like a dream now! Cost me 480€, but worth it for the peace of mind. Thanks for the advice!

Low brake fluid with a spongy pedal definitely suggests a leak somewhere in the system. It could be as simple as worn brake pads needing replacement, which would cause the fluid level in the reservoir to drop as the calipers extend further. However, it's also crucial to inspect the brake lines themselves for any signs of corrosion or damage, as well as the master cylinder. Have you checked for any visible leaks around the wheels or under the van?
