![]() The primary reason for this is that fixed calipers are more expensive to manufacture. Disadvantages of Fixed Calipersįixed calipers have many advantages, but there’s a reason why most cars use floating calipers. Because there’s no sliding mechanism, as the brake pads start to wear down, the pistons adjust automatically and fill in the void left by worn-out friction material.Ĭhanging the pads out is extremely simple and requires no disassembly. They need less maintenance in comparison to floating calipers.Īnother cool thing about fixed calipers is that they’re self-adjusting. These calipers also have a longer service life owing to fewer moving components. Not only does the aluminum construction allow for a lightweight design, but it also dissipates heat really well and it doesn’t rust or corrode. This makes for a slight reduction in unsprung weight which is always a good thing. Plus the pad wear remains nice and even.įixed calipers are fairly lightweight because they’re constructed from aluminum alloy. Moreover, the brake fluid generally doesn’t get as hot with fixed calipers, which means brake fade won’t occur as quickly as it would with overworked floating calipers. Because of how rigidly fixed calipers are secured, they offer consistent braking performance and pedal feel. Increased stiffness is another advantage. This is ideal if you frequent the track or if your car is faster than what it was intended to be. ![]() The most notable advantage with these is equal distribution of clamping force between the inward and outward pistons which results in better braking performance overall. Fixed Caliper AdvantagesĮven though floating calipers are the industry standard, you can always go in for an upgrade and install fixed calipers. This is something you can calculate for the purposes of comparing two different brake units.īelow we’ve listed some of the pros and cons of both fixed and floating calipers. Most importantly, if all other variables are considered equal, it is the area of the pistons that affects the stopping power the most. ![]() And besides, braking performance depends on factors such as the effectiveness of the master cylinder, caliper clamping pressure, brake pad material, tires, car weight, and suspension geometry to name a few.
