The Carbotech CT1417 brake pads offer world-class stopping power across a range of compounds engineered for HPDE, club racing, time trials, and daily driving. Whether you're shaving tenths at a national event or building consistency during weekend track days, there's a Carbotech compound tailored to your performance goals. Manufactured in the USA using Carbotech’s proprietary ceramic and metallic formulations, these pads deliver unmatched modulation, rotor friendliness, and fade resistance. Friction materials have evolved significantly over the years. Brake pads were originally made with organic ingredients such as asbestos and carbon, held together by a strong resin. Most brake pads sold today are considered semi-metallic, semi-metallic brake pads use brass, copper, and steel wool shavings held together by a resin. Unfortunately, the main drawback about the use of steel strands, iron, graphite, and small amounts of filer and friction modifiers (used to provide strength and conduct heat away from the rotors) is that the metal shavings and iron must rub against steel rotors every time the brakes are applied. This generates more noise and is a lot more abrasive on the rotors. It also creates corrosive dust that can damage your braking system as well as the paint on your wheels and car. Friction materials that contain Ceramic Kevlar formulations have become recognized for their desirable blend of traits. This allows the Ceramic Kevlar pads to handle higher brake temperatures with less heat fade, and provide faster recovery after heavy braking. It also reduces brake dust and makes wheel maintenance easier! Ceramic Kevlar compounds extend brake life compared to most other semi-metallic and organic materials, and at the same time they outlast other premium pad materials by a significant margin, without compromising in noise control, pad life, and all around braking performance. The CT1417 shape fits a variety of high-performance applications, making it a go-to solution for drivers looking for track day brake pads that match their skill level and intensity.

Which Carbotech compound is best for daily driving? 1521 is ideal for spirited street use with minimal dust and noise.. 2. What’s the best compound for beginner HPDE drivers? XP8 is a great starting point for advanced HPDE, offering strong bite and fade resistance without being overly aggressive. 3. Can I mix Carbotech compounds front and rear? Yes, many drivers use a more aggressive compound in the front (e.g., XP12) and a slightly less aggressive one in the rear (e.g., XP10) to fine-tune balance. 4. Are Carbotech pads hard on rotors? No. All Carbotech compounds are known for being rotor-friendly, helping reduce rotor wear and operating costs. 5. Which compound is best for endurance racing? RP2 is engineered specifically for long-distance events where pad and rotor life are just as important as torque output. 6. Do Carbotech pads require special bedding procedures? Yes. A proper bedding-in process is critical for optimal performance. Carbotech provides detailed bedding instructions with every set of pads. Carbotech Brake Pad Bedding Procedures The bedding process transfers friction material from the pads into the pores of the brake rotor. It also matches the microscopic contours of the pads and rotors to increase surface contact. Proper bedding of pads & rotors will result in greater performance, longer pad life & less rotor wear. Failure to properly bed in your pads could lead to friction materials chunking and breaking up. This could also lead to overheating your pads and causing them to glaze over resulting in the car not being able to stop or slow fast enough. All new brake pads require a bedding process. The proper way to bed your brake pads and brake discs (rotors) is to bed them on the racetrack, NOT on the street. Start this process by pumping your brakes a few times to assure proper installation. Once on track perform several moderate (medium) near stops (to a very slow rolling speed) to thoroughly warm up the pads and rotors. This should take 1-2 laps. This allows a thin layer of the pad material to be transferred into the micro-grooves of the rotor. After the pads/rotors are warm, perform a series of hard near stops (to a slow rolling speed) until some brake fade is felt. This process should take about 2-4 laps (depending on the track). Once this occurs, then stay off the brakes (as much as possible) and bring your car into the pits/paddock to completely cool. Do not lock the tires during this operation. Allow brake pads and/or rotors cool down to ambient temperatures; no less than 30 minutes. The total bedding procedure should not take more than 5-6 laps or about 10-15 minutes. Failure to properly bed in your pads could cause friction material to chunk and break up resulting in poor pad performance and pad life. Improper bedding can also lead to overheating your pads and causing them to glaze over, resulting in the car not being able to stop or slow properly.

A proper bedding-in process is critical for optimal performance. Carbotech provides detailed bedding instructions with every set of pads. Carbotech Brake Pad Bedding Procedures The bedding process transfers friction material from the pads into the pores of the brake rotor. It also matches the microscopic contours of the pads and rotors to increase surface contact. Proper bedding of pads & rotors will result in greater performance, longer pad life & less rotor wear. Failure to properly bed in your pads could lead to friction materials chunking and breaking up. This could also lead to overheating your pads and causing them to glaze over resulting in the car not being able to stop or slow fast enough. All new brake pads require a bedding process. The proper way to bed your brake pads and brake discs (rotors) is to bed them on the racetrack, NOT on the street. Start this process by pumping your brakes a few times to assure proper installation. Once on track perform several moderate (medium) near stops (to a very slow rolling speed) to thoroughly warm up the pads and rotors. This should take 1-2 laps. This allows a thin layer of the pad material to be transferred into the micro-grooves of the rotor. After the pads/rotors are warm, perform a series of hard near stops (to a slow rolling speed) until some brake fade is felt. This process should take about 2-4 laps (depending on the track). Once this occurs, then stay off the brakes (as much as possible) and bring your car into the pits/paddock to completely cool. Do not lock the tires during this operation. Allow brake pads and/or rotors cool down to ambient temperatures; no less than 30 minutes. The total bedding procedure should not take more than 5-6 laps or about 10-15 minutes. Failure to properly bed in your pads could cause friction material to chunk and break up resulting in poor pad performance and pad life. Improper bedding can also lead to overheating your pads and causing them to glaze over, resulting in the car not being able to stop or slow properly.
