Many knights know that it is more important to stay faster than to run faster. Therefore, in addition to improving the dynamic performance of the vehicle, the braking performance cannot be neglected. Many small partners also like to modify the calipers.
Before you upgrade your car's calipers, have you got it clear about its working principle, parameters, configuration, etc? Is it expensive to use the calipers? What is the recent recall of the world famous brand Brembo?
What is the difference between one-way and opposite calipers?
Literally, a one-way caliper means that only one side of the caliper has a piston design and the other side is a fixed brake pad. Therefore, the one-way calipers are equipped with a floating pin design, allowing the calipers to move left and right, so that the brake pads on both sides can be snapped to the disc.
â–²One-way calipers will be equipped with floating latch design
The opposite caliper has a piston design on both sides of the caliper, which uses hydraulic pressure to push the brake pad to clamp the disc. In the performance of the brakes, the opposite calipers are obviously better than the one-way calipers, so the commonly used modified calipers on the market are mostly opposite designs.

â–²The way of facing the caliper with two side clamps
In addition to high efficiency, the self-twisting condition of the opposing calipers is also smaller than that of the one-way calipers. Based on the floating pin design and the minimum piston area, the one-way calipers inevitably produce a greater degree of bending.
What is the radiation caliper?
The English name of the radiation caliper is Radial Mount Calipers, also known as radial calipers. Radiation calipers differ from conventional calipers in that the screws at both ends are locked in a radial manner, unlike the conventional caliper side locks. Radial locking can reduce lateral shear.
â–² Radiation calipers are locked in a radial manner
When the caliper operates, it will produce some self-distorting, severe self-distortion, which will cause the brake pads to form a radial conical wear.
â–² Radial tapered wear brake pads
This problem can be effectively improved by the radial locking method of the radiation caliper. This is why many riders feel that the radiation caliper brake performance is more stable.
Non-radial caliper modification can achieve the effect of radiation calipers? Not exactly the same. The advantage of the radiation caliper is that its radial locking point and many radiation calipers on the market are transferred by the caliper seat. In this way, the caliper seat also has lateral shearing force.
Although the caliper type lift will bring more braking force, it does not really take advantage of the radiation caliper.
Which is better for casting and forging?
The answer is forged calipers. For the same material, forging has stronger rigidity than casting, while under the same rigidity, forging is lighter than casting.
â–²Brembo GP4-R integrated caliper
In addition, forging and casting can be subdivided into one-piece and two-piece calipers, and the integrated type can further improve the caliper strength and reduce the writhing of the caliper. However, the integral forming process is much more difficult than the two-piece caliper. Many, plus the cost of the machine, so the integrated calipers are high-end calipers, so it is not common in the market.
What materials are the pistons made of?
Material: titanium alloy, aluminum alloy, iron; influencing factors: heat dissipation, oxidation. The piston is the intermediate medium for the brake oil to push the brake pad. When the caliper works, the brake pad will generate high temperature due to friction. Under the conduction of the piston, the brake oil temperature will gradually rise. Brake oil that exceeds the operating temperature loses conductivity.
Therefore, the material with faster heat dissipation can provide more stable braking performance. The material also affects the performance of the piston. For example, a rusty piston will create resistance during exercise. Common materials for pistons are titanium alloy, aluminum alloy and iron from high to low.
Among the pistons recalled by Brebo in the near future, special pumps are used for the upper pump. However, the results prove that there is no metal reliable.
Must you change the caliper?
If you want to achieve better braking and feel. Modified calipers can really help you achieve your goals, but if you feel that the brakes are not strong enough, you can try to start from changing the brake pads and then step up.
Moreover, the unit price of the brake pads is lower than that of the modified calipers, naturally it can avoid unnecessary spending of more flowers!
