The reason why the brake feels softer after replacing the brake pads is that they may not have been properly broken in yet. Types of brake pads: Asbestos brake pads (mostly obsolete), semi-metallic brake pads, low-metallic brake pads, NAO formula brake pads, ceramic brake pads, NAO ceramic brake pads. Ceramic brake pads vs. traditional brake pads: In traditional brake pads, metal is the primary material that generates friction, providing strong braking force but with significant wear and a tendency to produce noise. After installing ceramic brake pads, abnormal squealing (i.e., scraping sounds) will not occur during normal driving. Since ceramic brake pads do not contain metal components, they avoid the metal squealing noise caused by friction between traditional metal brake pads and their counterparts (i.e., the brake pads and brake discs).

I also experienced softer brakes right after changing the brake pads, which is quite common. It might be because the new brake pads haven't fully adapted yet, and they usually need about tens of kilometers to break in before improving. Another possible reason is that air might have entered the brake system during installation, causing the brake pedal to feel soft and lack sufficient force. You should check the brake fluid reservoir level and top it up with the same type of fluid if it's low. If you don't have the tools to bleed the brakes yourself, it's best to drive to a repair shop and let a professional handle it—safety first. New brake pads can be a bit slippery at first, so avoid slamming the brakes too hard and give them some time to adjust. Also, pay attention to tire positioning when parking to prevent aggravating the issue.

I've encountered this situation before, mostly due to improper bleeding when replacing brake pads, leaving air trapped in the hydraulic system which affects braking pressure. The new pads have a smooth surface that requires bedding-in; they'll perform evenly after some driving. First, check if the fluid level in the reservoir is normal and top it up if low. Try gently pumping the brakes several times in succession to help purge any air. If the sponginess persists for more than two days or you notice significant weakness at high speeds, it could indicate deeper issues like caliper or master cylinder failure. To prevent accidents, have a reliable technician perform a thorough inspection—after all, brake safety is a matter of life and death. Remember to discuss maintenance details with the shop in advance next time.

Soft brakes after replacing brake pads may be caused by the overly smooth surface of the new pads initially, resulting in insufficient friction, which will improve after a few days of driving. However, if air enters the system, it can cause the pedal to sink, requiring a thorough bleeding. Check if the brake fluid is sufficient and top it up promptly if needed. Ignoring this issue poses a significant risk of delayed brake response during turns, so it's best to visit a professional shop the same day for resolution. Always use genuine parts during maintenance to ensure compatibility.
