Paragon Track Performance Big Brake Kit (PA055 4 piston) - Mini Cooper R53 / R56 Front

INSTALLATION MANUAL

This complete, track ready brake kit features the same PA055 4 piston calipers that Team Honda Research West use on their 25 Hour of Thunderhill 11th Gen Civic Si endurance race cars. Many of its components have been track-proven with multiple 25-hour endurance race wins.

• Fully-floating 2-piece rotors, with directional ventilation vanes for optimal cooling performance. Runs up to 30% cooler than O.E. rotors
• Hard anodized calipers and rotor hats for increased resistance to wear and discoloration under extreme track conditions
• Piston sizes optimized for each application. Designed to work flawlessly with OEM ABS and brake master cylinder. Compatible with OEM rear brakes
• Confidence-inspiring heat resistance during extended sessions. Optimum bite, modulation characteristics, thermal stability, and durability
• Recommended usage: Street / Track
• Complete pre-assembled axle set

Includes:

• One pair of Paragon PA055 4 piston calipers
• One pair of Paragon fully-floating 2-piece rotor assemblies with hard anodized 6061-T6 aerospace grade aluminum hats, stainless steel bobbins, and anti-rattle clips
• One set of Paragon P3 "Street/Track" semi-metallic brake pads (manufactured by Winmax Japan, other compounds available at additional cost)
• One pair of caliper mounting brackets and all necessary hardware
• One pair of Goodridge DOT approved stainless steel braided brake lines
• One set of caliper anti rattle clips
• Detailed installation manual

Application: 

• 2000-2006 Mini Cooper R53 Front
• 2006-2013 Mini Cooper R56 Front

PA055 4 Piston Calipers

• CNC machined from billet 6061-T6 aluminum
• Outstanding rigidity. Reduces compliance which allow for a consistent pedal feel, and improves responsiveness/modulation characteristics
•  Titanium nitride (TiN) coated pistons. Improve durability and extend service intervals by protecting the sliding surfaces of the pistons. Allow smooth piston travel

• Stainless steel pistons can act as an effective thermal barrier due to the lower thermal conductivity vs. aluminum pistons, which help prevent brake fluid boiling and brake fade. Extra machining is done to minimize contact with the pads
• Staggered piston bore sizes for improved brake balance and even pad wear
• High temperature piston seals and internal dust seals are utilized to withstand the heat generated under harsh track conditions and extend caliper service life. Internal dust seals are able to offer protection against debris/contaminants and will not melt as easily as the external dust boots that are commonly used on OEM calipers

• Hard anodized finish for improved wear resistance. Unlike painted/powder coated calipers, hard anodized finish will not deteriorate under extreme heat
• Replaceable stainless steel abutment plates to allow smooth braking action and prevent wear on the caliper body
• Strong, yet lightweight. Each caliper weighs 5.4 lbs (without pads)
• Optional anti-knockback springs
• Stainless steel bleed screws and crossover pipes
• Each caliper is pressure tested to guarantee proper operation

Floating 2-piece Rotors

• Floating 2-piece design allows thermal expansion of the rotor while minimizing deformation and ensuring the rotor is self-centered with the pads
• Superior braking and cooling performance
• Features directional ventilation vanes to create suction, turbulence, and guides cool air through the rotor for improved heat dissipation and increased resistance to cracking
• Made of CM-250 special formulated high carbon alloy cast iron. Allows for an optimal bite, thermal characteristics, high-temperature strength, and durability
• Heat treated to release stress in the rotor to avoid deformation and vibration
• State-of-the-art CBN surface machining to ensure better break-in with new brake pads
• Excellent thermal capacity. Allows the rotors to absorb and dissipate heat more efficiently and help reduce chance of brake fade
• Replacement rotor rings available at competitive price

Curved Directional Ventilation Vanes

Features directional ventilation vanes to create suction and turbulence, and guide cool air through the rotor to achieve better heat dissipation and increased resistance to cracking under harsh track conditions. Each rotor is left or right side specific, and the ventilation vanes are optimized to spin in a particular direction to pump the maximum amount of cool air through the rotor. This design allows the rotor to run up to 30% cooler than O.E. rotors and increases cooling efficiency by up to 30% over standard 1-piece units. Brake fade and judder are minimized during extended sessions. This means the brake system can withstand heavier track usage and provide consistent braking performance lap after lap.

Slotted Friction Face

Slotted rotor face pattern improves brake consistency by constantly cleaning the contact surface and dissipate heat generated, and gases released when the pads come into contact with the rotors. Slotted rotors have a superior advantage over blank rotors in wet or raining conditions by preventing water films to form between the brake pad and rotor surface.

Hard Anodized Aluminum Hats

• CNC machined from lightweight 6061-T6 aerospace grade aluminum
• Unsprung weight reduction
• High strength and durability
• Hard anodized to increase resistance to wear, corrosion, and discoloration

Floating Bobbins & Mounting System

Utilizes T-Bobbin rotor to hat mounting system to allow "float" in both radial and axial directions, and minimize brake judder. The high quality stainless steel hardware are corrosion resistant which allows secure mounting, and smooth expansion and contraction throughout heat cycles. Anti wear clips (McLaren spring clips) are utilized to slightly pre-load the rotor assembly and minimize rattling noise.

Caliper Mounting Brackets

CNC machined caliper mounting brackets to ensure superior strength, durability, and secure mounting of calipers to knuckles.
