What is the difference between a four-piston caliper and a regular caliper?

[StCassidy]

The differences between a four-piston caliper and a regular caliper are as follows: 1. Different number of pistons: Generally, family cars with disc brakes use single-piston calipers, while modified cars use four-piston caliper brakes. 2. Different braking force: The more pistons a brake caliper has, the greater, more stable, and smoother the braking force. Therefore, a four-piston caliper provides stronger braking force than a regular caliper. Here are the advantages of disc brakes: 1. Better heat dissipation: Disc brakes dissipate heat better than drum brakes, reducing the likelihood of brake fade and failure during continuous braking. 2. Faster response: Disc brake systems react quickly, allowing for high-frequency braking actions, which makes them more suitable for ABS systems. 3. More even braking force: Unlike drum brakes, disc brakes do not have a self-servo effect, resulting in more balanced braking force between the left and right wheels.
