Brembo Monobloc 4 Piston Brake Pads
(Ferodo compound code H)
The DS2500 is currently the best hybrid track/street pad on the market. It features the moderately high bite and solid fade resistance of a track pad, with the relatively low dust and noise levels of a street pad. When used as a street pad, it can produce some squeal on certain vehicle platforms. During aggressive driving the DS2500 is known for its flat torque curve, which means as temperatures go up, the response through the brake pedal remains consistent. If you drive aggressively on the street, do some canyon runs, autoX, and maybe some light track duty on street tires, the DS2500 is tough to beat.
When used on fast, heavy cars on the track with race tires, pad wear rates tend to be higher than some of the full track pad compounds. Under those conditions, Essex would recommend the Ferodo DS3000 or DS1.11.
The main characteristics of DS2500 are:
- Consistent coefficient of friction (0,42) at all temperatures
- Low noise
- low dusting
- Long pad life
- Kind on discs
- Race pedal fee
(Ferodo compound code R)
DS3000 is one of the most decorated race pads in the global motorsports market, having won in diverse venues from rally to open wheel cars. The DS3000 has high bite and good fade resistance. It has a slightly rising torque curve, which means that as temperatures go up, bite increases slightly. Although the bite of the DS3000 is slightly higher than the DS1.11, wear rates are also higher. If you are doing extended lapping (30 minute+ sessions) or endurance racing, and are concerned about pad wear rates, the DS1.11 is probably the better choice for you.
The main characteristics of the DS3000 are:
- Very High coefficient of friction (0,54) at all speeds and temperatures
- High initial bite
- Predictability and control because of the unvarying torque output
- Low off-brake drag
(Hawk compound code G)
The DTC-60 was designed as a rear application for those running DTC-70 in their front calipers. The DTC-60 has slightly less bite than the DTC-70, and when run with the DTC-70 in the front, the balance remains a bit more front biased and stable (all else held equal).
High torque with less initial bite than DTC 70. Superior release and torque control characteristics. Brake pads designed for cars with high deceleration rates with or without down force. Recommended for use with DTC-70 when split friction between front and rear axle is desired.
(Hawk compound code U)
The DTC-70 is one of Hawk's newest motorsport compounds, offering the highest bite and heat capacity in Hawk's range, along with improved pedal modulation. The DTC-70 is a popular pad across a very wide range of racing venues, and has become the pad a choice in numerous SCCA and NASA Series. Many customers report that the pad performs very similarly to the PFC01 on track. DTC-70 is typically used as a front application, and on front engine cars is commonly coupled with DTC-60 or HT-10 in the rear.
Extremely high torque with aggressive controllable initial bite. Superior release and torque control characteristics. Brake pads designed for cars with high deceleration rates with or without down force.
The RC5+ is CL’s latest offering, and was developed with the autoX and track day crowd squarely in mind. It is a well-mannered race pad, with lower noise, low dust, and a lower coefficient of friction. The beauty of this compound is that despite its mild manners, it still retains a very high max operating temperature. It is a great choice for lighter cars on race tires, or heavy, high power cars on street tires. The failure mechanism of this pad is one of its greatest strengths. If you do happen to push it over its temperature threshold, bite slowly tapers away rather than falling off a cliff, so you’ll easily recognize when it’s time to back off. It’s extremely wear resistant, and doesn’t destroy rotors with pad deposits when pushed to their temperature envelope. The RC5+ is a great rear pad option for those who like a more front biased setup with the RC6 or RC6E compound up front.
The best way to describe the wear rates on this compound is ‘ridiculous.’ You can hammer them over and over, and they just don’t wear out. In independent dyno testing, the RC6E showed wear rates that were as much as five times lower than some of the currently popular semi-metallic race pads. While having slightly lower bite than the RC6, the RC6E still has more bite than most other race pads on the market. They’re also extremely easy on rotors. They initially appear expensive, but when you factor in how long they will last (along with your rotors), they’re actually a tremendous value.
The first thing you’ll notice about them is the incredibly high, yet controllable bite. You’ll likely use less pedal pressure than you’re accustomed to, which means no more standing on your brake pedal praying for the car to stop while diving into turns. You’ll also have incredible cold bite, which is of great value to autoX and Time Attack participants, who typically have little or no time to warm up their brakes prior to timed runs. Regardless of your engine package, tires, or the track you’re driving, it’s highly unlikely that you’ll ever fade the RC6 compound. Since the material is so dense, the RC6 feels rock-hard underfoot. The RC6 has become a bread and butter pad among rally drivers in Europe due to its relentless bite in every imaginable track and weather condition. Most experienced drivers have a ‘wow’ moment the first time they drive the RC6, as they’ve never felt anything quite like it before. The RC6 is typically used on the front of most cars, although it’s a great rear pad option if RC8 is being used on the front.
Bite, bite, bite, and more bite. If you like a pad with a high coefficient and low pedal effort, then you’ll love the RC8. These pads are reserved for heavy, fast cars on race rubber, or pure race cars with downforce. Due to their extremely high coefficient of friction, it’s recommended that you only mate these pads up with other CL pads in the rear.
CL BRAKE PAD BACKGROUND
While most pads are formed from fibers and organic materials bonded together by resins, CL Brakes Sintered Pads begin as powdered metals such as iron, bronze, and copper, mixed with roughly ten other constituent materials including graphite and carbon. The mix is compressed in a tool under extreme pressure to give it shape, and then brazed onto a backing plate in an oven at 1800F. The resulting material is characterized by a consistently high coefficient of friction, stability at high temperatures, and an extremely low wear rates.
CL Brakes originally created sintered brake materials for military applications such as tanks, helicopters, and airplanes, as well as high speed freight and passenger trains like France’s TGV. After extensive development, the technology was successfully introduced in motorcycle applications. The most recent development has focused on aligning the sintered technology with racecars. CL Brakes have now been used successfully at the highest levels of motorsport, including World Rally Championship (WRC) and NASCAR Sprint Cup.
