Seat Alhambra Brake Pedal Feels Off

Alright, need some brainpower here. My 2013 Seat Alhambra with a gasoline engine (72991 km on the clock) has developed a rather unsettling issue. The brake pedal feels... off. It's hard to describe, but the feedback is just not right. I've been reading about potential causes, and undervoltage in the vehicle keeps popping up. Could this actually be the culprit? Any ideas before I start tearing things apart?

Summary of the thread

A 2013 Seat Alhambra owner reported an issue with the brake pedal feeling off and suspected undervoltage as a potential cause. Possible causes discussed included low brake fluid, worn brake pads, and rotors. It was suggested to inspect these components first, as they hadn't been checked in three years. The undervoltage theory was considered plausible, potentially affecting the ABS system. The owner took the car to a workshop, where it was confirmed that undervoltage was causing the issue, and the brake system was serviced, resolving the problem.

Strange brake pedal feedback on a Alhambra could be a few things. First, when was the last time you checked your brake fluid level and its condition? Low brake fluid or fluid that's absorbed too much moisture can definitely affect pedal feel. Also, have you inspected your brake pads and brake rotors for wear? Sometimes worn brake pads can cause unusual sensations. Squeaky brakes are also a classic symptom. Regarding the undervoltage, that's interesting. I'm not immediately seeing a direct connection, but modern cars have so many interconnected systems now.

Thanks for the quick reply! Brake fluid was last checked during the annual service about six months ago, but I haven't personally inspected it. Pads and rotors... well, I haven't touched those since I bought the car three years ago. As for the undervoltage, a friend with some electrical experience mentioned it could mess with the ABS system, leading to weird feedback. Is that plausible? What should I check next?

Okay, if the pads and rotors haven't been checked in three years, that's definitely the first place to look. Visual inspection will tell you a lot. Yes, undervoltage could theoretically affect the ABS, which could lead to strange pedal feel, but that's a less common scenario. Given the age of the components, I'd strongly suspect the brake pads or rotors are worn. My advice? Get it to a trusted workshop. Brake systems are critical, and this isn't something to guess at. They can properly diagnose the entire brake system, check the brake fluid, and see if the undervoltage theory holds any water.

Just wanted to let you know. Took it to the workshop today, and you were spot on! They checked the brake system and confirmed it was undervoltage causing the weird pedal feedback. New brake pads, brake fluid change, and rotors resurfaced. Total damage: 240€. Thanks again for your help!
