What are the reasons for the Peugeot 408's soft brakes and inability to stop effectively?

Here are the reasons for the Peugeot 408's soft brakes and inability to stop effectively: 1. Damaged vacuum booster pump: The vacuum booster pump used in the vehicle's braking system is damaged, the pipelines of the vacuum booster pump are broken, and there is no vacuum inside the vacuum booster pump. 2. Brake component failure: There is a failure in the vehicle's brake components, including the brake pads and brake calipers, which need to be repaired promptly. Below is extended information on related content: 1. Brake system: The Peugeot 408's brake system maintenance requires regular replacement of the vehicle's brake fluid and regular inspection of the vehicle's brake pads, brake hoses, and brake pump. During vehicle use, if it is found that the vehicle's brakes are not responsive or the braking effect is poor after stepping on the brakes, it is necessary to have the brakes inspected at a repair shop. Otherwise, it poses a significant safety hazard for vehicle operation. 2. Replacement time: The Peugeot 408's brake pads need to be replaced when the vehicle has traveled 30,000 to 60,000 kilometers. The vehicle's brake pads are consumables and are vulnerable components of the vehicle.

I've been driving my Peugeot 408 for several years, and sometimes the brakes feel particularly soft, making it hard to stop, which really gives me a cold sweat. It's mostly likely a brake fluid issue—either the fluid level is too low, or over time, it has absorbed moisture and mixed with air, making the pedal feel spongy. It could also be that the brake pads are worn to their limit, which directly affects braking performance. If they're completely worn out, they need to be replaced immediately—don’t delay. Additionally, warped brake discs or aging hoses leaking oil can cause the same problem. Last time I encountered this issue, I checked myself and found the fluid was a bit low. After topping it up, the situation improved. In short, this problem is about driving safety. I recommend checking the fluid and components every six months—early action can save you money and peace of mind.
