All-in-one Caliper,1.25 Dynapro Radial,.810" Disc Now 75% Cheaper [ev2xnI54]
WORKS WITH .810" ROTORS
FOUR 1.25" PISTONS
THE DYNAPRO FOUR-PISTON RADIAL MOUNT CALIPER COMBINES PURE RACE TECHNOLOGY WITH A NEW GENERATION OF WILWOOD PERFORMANCE ENHANCEMENTS
ITS SLEEK PROFILE, SUPERIOR STRENGTH, AND DURABILITY IN ADVERSE CONDITIONS ARE EASILY ADAPTED TO A BROAD RANGE OF SPORTS, RALLY AND OFF-ROAD DRIVING APPLICATIONS
THE STRENGTH OF THE DYNAPRO IS A COMBINATION OF PROCESS AND DESIGN
THE PROCESS OF STRESS-FLOW FORGING RE-ALIGNS THE METAL'S GRAIN STRUCTURE WITHIN THE CONTOUR OF THE CALIPER BODY
THIS ELIMINATES THE STRESSES AND INTERRUPTIONS TO THE INTERNAL GRAIN STRUCTURE THAT OCCUR WHEN MACHINING A STRAIGHT BLOCK BILLET
THE FEA GENERATED RADIAL TRANSITION DESIGN ELIMINATES STEPS AND SHOULDERS IN THE AREA BETWEEN THE PISTON HOUSING BODY AND THE CALIPER BRIDGES
INCORPORATING A RADIUS IN THIS CRITICAL AREA SUBSTANTIALLY INCREASES RESISTANCE TO DEFLECTION AND CALIPER SEPARATION UNDER LOAD
STRUCTURAL DEFLECTION AND VOLUME DISPLACEMENT TESTS HAVE PROVEN THE EFFICIENCY OF THIS INNOVATIVE DESIGN
WITHOUT EVEN CONSIDERING THE OVERALL GREATER STRENGTH AND RELIABILITY OF THE BILLET FORGING, THE REDUCTION IN OVERALL DEFLECTION AND FLUID VOLUME DISPLACEMENT TRANSLATE TO INCREASED CLAMPING EFFICIENCY WITH LESS PEDAL TRAVEL
THE BOTTOM LINE IS A FIRM PEDAL WITH OUTSTANDING STOPPING POWER
THE SUPERIOR STRENGTH OF THIS INNOVATIVE DESIGN IS COMBINED WITH A NEW GENERATION OF WILWOOD PERFORMANCE FEATURES
THE DYNAPRO USES A NEW 7816 TYPE BRAKE PAD THAT IS SUPPORTED FROM THE TOP BY QUICK-CLIP PAD RETAINERS
THIS FEATURE ELIMINATES THE NEED FOR A PAD SUPPORT STEP IN THE BOTTOM OF THE CALIPER AND ADDS ADDITIONAL CLEARANCE FOR MOUNTING CLOSER TO THE HUB ON SMALL WHEEL AND SMALL ROTOR APPLICATIONS
THE PAD RADIUS MATCHES TO ROTOR DIAMETERS BETWEEN 9.45" (240,0MM) AND 12.19" (309,6 MM), AND THE CALIPER FITS EASILY INSIDE MANY 13.00" WHEEL APPLICATIONS
THE QUICK-CLIPS ALSO ACCOMMODATE EASY PAD ACCESS WITHOUT CALIPER REMOVAL
OTHER NEW WILWOOD FEATURES INCLUDE COATED ALUMINUM PISTONS FITTED WITH HIGH TEMPERATURE RUBBER BOOTS THAT SEAL OUT DIRT, MOISTURE, AND DEBRIS FROM THE PISTON BORES IN LESS THAN FRIENDLY ENVIRONMENTS
EVERY CALIPER IS EQUIPPED WITH WILWOOD'S SRS STAINLESS STEEL BRIDGE PLATES
THE SRS PLATES ELIMINATE THE BRIDGE WEAR CAUSED BY PAD GOUGING AND EXTEND THE SERVICE LIFE OF THE CALIPER BODY
THE SPRING-LOADING ACTION OF THE SRS PLATES ALSO ELIMINATES PAD RATTLE AND DAMPENS THE VIBRATION HARMONICS THAT CONTRIBUTE TO SQUEAL UNDER BRAKING
INTERNAL FLUID PASSAGES ELIMINATE THE NEED FOR EXTERNAL TUBES
FOUR CORNER BLEED SCREWS ASSURE SIMPLE AND EFFECTIVE AIR EVACUATION, AND ALLOW ONE CALIPER TO BE MOUNTED IN ANY FRONT, REAR, RIGHT OR LEFT POSITION
NOTE: FOR SUSTAINED HIGH TEMPERATURE OPERATION IN SEVERE DUTY COMPETITION, THE DYNAPRO CAN BE FITTED WITH ONE PIECE STAINLESS STEEL OR WILWOOD'S EXCLUSIVE THERMLOCK PISTON TECHNOLOGY WITHOUT THE DUST BOOTS
