▷▷ 2021 ▷ Ceramic vs. Kevlar brake pads

5 julio, 2021

Semi-metallic brake pads were developed to cope with the high heat generated by downsizing disc brake systems in the 1980s. As a result, we began to see increases in brake rotor wear, excessive dust brakes and screeching (along with other noises). Buyers of these vehicles had serious problems with this, and technicians struggled with these problems on a daily basis, specifically brake noise. Kevlar pad compounds began to arrive in the 1990s to address these problems. Made of Kevlar and steel, it is still considered a semi-metallic pad, but the higher concentration of Kevlar significantly reduced noise. Lower dust levels were also achieved, but wear is still an issue. The newer pottery seems to address all of these concerns. Dust, excessive wear and noise seem to be a thing of the past. However, the downside to ceramic pads occurs during cold weather. The first stops of a vehicle equipped with ceramic pads show a decrease in braking efficiency. Once the pads warm up, this problem goes away.
