What is the difference between ventilated discs and disc brakes?
2 Answers
The differences between ventilated discs and disc brakes are: 1. Different application positions: Ventilated disc brakes are primarily applied to all four wheels, while disc brakes mainly function on the rear wheels. 2. Different braking effects: Ventilated discs can quickly dissipate heat during braking, whereas disc brakes may experience reduced braking efficiency due to heat buildup. The working principle of ventilated discs is: The centrifugal force generated while the car is moving enables air convection, achieving heat dissipation. The working principle of disc brakes is: The brake pads on the calipers interact with the brake discs connected to the wheels during braking until the wheels stop rotating.
I've got a lot to say about brake system upgrades! Back when I was driving on mountain roads, I kept smelling this burnt odor, which got me thinking about the difference between vented discs and solid discs. Vented discs have cooling channels sandwiched in the middle, like installing an exhaust fan for the brake pads—heat dissipates quickly during high-speed hard braking. After upgrading my hot hatch to vented discs, I never experienced brake fade again during consecutive cornering. Solid discs, on the other hand, are like chunks of iron—cheap and durable, but when you're stuck in summer traffic and brake until smoke comes out, it feels like stepping on cotton. They tend to warp and vibrate after about 150,000 km. Many economy cars use solid discs on the rear axle to save costs while pairing vented discs up front for safety. Now you see why tuning shops always recommend vented discs!
