Once heat builds or you're leaning on the pedal repeatedly, it fades and the pedal goes long. This is PRL's fixed four-piston replacement, forged 6061-T6 with 44mm and 41mm pistons, working with your OEM 312mm rotor and including the stainless lines the system needs.\u003c\/p\u003e\n\n\u003ch4\u003eCheck Your Wheel Clearance First\u003c\/h4\u003e\n\n\u003cp\u003eThe most important thing on this page, and PRL gave you the tool to do it properly.\u003c\/p\u003e\n\n\u003cp\u003eThis caliper is considerably larger than the factory one. It adds roughly \u003cstrong\u003e25mm of outward width\u003c\/strong\u003e and \u003cstrong\u003e30mm of height at both top and bottom\u003c\/strong\u003e, which is 60mm of additional overall height.\u003c\/p\u003e\n\n\u003cp\u003eThat extra size is where the thermal mass and improved pad contact come from, and it's also why it won't clear every wheel.\u003c\/p\u003e\n\n\u003cp\u003ePRL provides a printable PDF fitment template so you can verify before ordering. Print it at 1:1 scale, check it against a tape measure to confirm the scaling came out right, and test it against your wheels.\u003c\/p\u003e\n\n\u003cp\u003eTwo minutes with a printer beats discovering a clearance problem with the old calipers already off.\u003c\/p\u003e\n\n\u003ch4\u003eFixed Caliper Versus Floating\u003c\/h4\u003e\n\n\u003cp\u003eWorth understanding, because it's the fundamental difference here.\u003c\/p\u003e\n\n\u003cp\u003eA floating caliper has pistons on one side only. Pressing the pedal pushes the inner pad against the rotor, and the caliper body slides on pins to pull the outer pad in. It works, and it's cheap to manufacture, which is why Honda uses it.\u003c\/p\u003e\n\n\u003cp\u003eThe problems show up under load. The slide pins introduce compliance, the two pads don't apply pressure evenly, and everything flexes more as the system heats up. What you feel is a pedal that gets longer and less confident as a session goes on.\u003c\/p\u003e\n\n\u003cp\u003eA fixed caliper has pistons on both sides and doesn't move. Both pads get clamped directly with equal pressure, there are no slide pins to bind or flex, and the rigid two-piece forged body resists deflection under hard braking.\u003c\/p\u003e\n\n\u003cp\u003eThe result is a firmer pedal that stays firm, more consistent bite, and considerably better behavior once things are hot.\u003c\/p\u003e\n\n\u003ch4\u003eStandard Parts, Deliberately\u003c\/h4\u003e\n\n\u003cp\u003eThis is the design decision worth appreciating, and it saves you money every time you service the brakes.\u003c\/p\u003e\n\n\u003cp\u003ePRL built this around the \u003cstrong\u003e312 x 25mm rotor\u003c\/strong\u003e already used on the 10th and 11th gen Civic Si, rather than a proprietary size. That means replacement rotors are widely available and inexpensive, and you're not waiting on a specialty part when you need one.\u003c\/p\u003e\n\n\u003cp\u003eThe pad shape is \u003cstrong\u003eFMSI D1001\u003c\/strong\u003e, the same profile used on the FK8 Civic Type R, the Brembo F50, and the Subaru STI. That's one of the most widely supported performance pad shapes available, so you can run whatever compound suits your use without hunting for something obscure.\u003c\/p\u003e\n\n\u003cp\u003ePlenty of big brake kits lock you into parts only one company sells. This deliberately doesn't.\u003c\/p\u003e\n\n\u003ch4\u003eHow It's Built\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eCalipers\u003c\/strong\u003e are forged 6061-T6 aluminum in a two-piece body, hard anodized for thermal resistance and corrosion protection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePistons\u003c\/strong\u003e are 44mm primary and 41mm secondary, machined from 6061-T6 billet and vented with Type 3 hard anodizing. The staggered sizing is intentional, it evens out pad pressure across the contact patch as the pad wears.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBrackets\u003c\/strong\u003e are CNC machined from 4140 billet steel with an electrocoated finish, which is where the strength needs to be since that's what ties the caliper to the knuckle.\u003c\/p\u003e\n\n\u003cp\u003eRoughly 8.8 lbs per side including bracket and hardware.\u003c\/p\u003e\n\n\u003ch4\u003eThe Lines Aren't Optional\u003c\/h4\u003e\n\n\u003cp\u003eStainless braided brake lines are included and they're required rather than an upgrade.\u003c\/p\u003e\n\n\u003cp\u003eRubber lines expand under pressure, which means part of your pedal effort goes into swelling a hose instead of clamping the pads. Fitting four-piston calipers behind expanding lines would waste much of what you just bought.\u003c\/p\u003e\n\n\u003cp\u003eSince the lines are in the box, that's handled. Just plan for a proper bleed afterward, since air in the system undoes the firm pedal you're paying for.\u003c\/p\u003e\n\n\u003ch4\u003eRotors And Pads Sold Separately\u003c\/h4\u003e\n\n\u003cp\u003eBeing clear so nothing surprises you.\u003c\/p\u003e\n\n\u003cp\u003eThe kit includes calipers, brackets, lines, and hardware. It does \u003cstrong\u003enot\u003c\/strong\u003e include rotors or pads.\u003c\/p\u003e\n\n\u003cp\u003eIf you're on the factory 312mm rotors and they're in good shape, they carry over. If you're going outside OEM spec on rotors or pads, check PRL's install guide to verify compatibility before ordering.\u003c\/p\u003e\n\n\u003ch4\u003eBlue Or Gray\u003c\/h4\u003e\n\n\u003cp\u003eTwo anodized finishes, and it's purely a look.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBlue (1167-1-BLU)\u003c\/strong\u003e is the statement choice, visible through the wheel and obvious that something's been done.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGray (1167-1-GRY)\u003c\/strong\u003e is the subtler option, closer to a factory appearance while still reading as a proper caliper up close.\u003c\/p\u003e\n\n\u003cp\u003eBoth are hard anodized, so both resist heat and corrosion identically.
