On the other hand, the Yamaha XS650E, released around the same time in 1971, had opposed-piston brake calipers, which were touted to be superior to those used on racers at the time.Īlthough opposed brakes give the impression of being more elegant and higher performance than single-sided brakes, single-sided brakes have the advantage of being easier to install in spoked wheel cars because they do not protrude to the inside of the wheel. The Honda CB750 Foer, the first production bike to use disc brakes, was the first to use single-piston brake calipers, and the Kawasaki Z2 followed suit. Strictly speaking, even if there is a time difference, it is so small that there is no problem with the effectiveness of the brakes. The literal representation makes it seem like there is a time difference in the movement of the pads on the front and back, but in reality, the pad strokes are so slight that they are sandwiched between the front and back of the rotor at the same time. With this combination, the caliper pistons try to come out more and more when you pull the brake lever, but on the front side, the pads hit the rotor and can't move forward anymore, so the caliper itself moves outward, which creates a force that pulls the pads on the backside toward the backside of the rotor. These pins are in a parallel relationship with the caliper bolt, allowing the caliper to move thrust-wise against the bolted caliper bracket. The calipers on the single-push pistons are always secured to the front forks via the caliper brackets, and the calipers and brackets are floated together by two pins. Still, the pads can pinch the front and back of the rotor, thanks to the work of the sliding pins. That means you're not pushing the pads directly from behind the rotor. When you look at the motorcycle from the outside, you can see the caliper body where the pistons fit, but on the inside of the wheel, you can see the brake pads directly in contact with the backside of the rotor. In contrast, a single-piston caliper has the pistons on only one side. Next, if we look at the calipers, the opposing piston-type has the caliper pistons literally facing each other so that the brake pads can be pushed out of the front and back at the same time. If you look at the relationship between the brake rotor and the brake pads, the rotor is pinched by the brake pads from the front and back at the same time. The principle of disc brakes is that when you grip the brake lever, the caliper piston pushes on the brake pads and pinches the brake rotor to control the speed. Attached to the front fork is a caliper bracket, and the caliper has two pins on the bracket that are inserted into the caliper. The caliper pistons are on one side only (left side in the example in the image) relative to the rotor, and on the other side only the pads.
