Why does the brake feel softer after replacing ceramic brake pads?
2 Answers
When replacing the brake fluid, if the air in the brake system is not completely bled out, the brake may feel softer due to air resistance. Below is an introduction to brake pads: 1. Concept of brake pads: Automotive brake pads, also known as brake linings, are fixed to the rotating brake drum or brake disc of the wheel. The friction lining and friction block within them withstand external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. 2. Structure of brake pads: The heat insulation layer is made of non-heat-conductive materials to insulate heat. The friction block consists of friction materials and adhesives. When braking, it is pressed against the brake disc or drum to generate friction, thereby achieving the purpose of vehicle deceleration and braking.
Having driven for over a decade, I've found it quite common to experience softer braking after switching to ceramic brake pads. Ceramic pads are harder than standard metallic ones, so they require a break-in period—usually about 100-200 miles—to reach optimal performance. Initially, the pedal may feel spongy because the pad surface hasn’t fully seated against the rotor. These pads do offer advantages, though: less noise, reduced dust, longer lifespan, and cost savings in the long run. But you’ll need some time to adjust—I was worried too when I first used them, but it’s nothing serious. Regularly checking brake fluid levels and bleeding the system is crucial; trapped air can exaggerate the softness. Proper installation ensures safer driving. Bottom line: give new pads 1-2 weeks to bed in—don’t rush, they’ll stabilize soon enough.
