Wilwood Dynapro 6 Big Brake Front Brake Kit (Hat) - Manual (Page 5)

Assembly Instructions (Continued)
•NOTE: OEM rubber brake hoses generally cannot be adapted to Wilwood calipers. The caliper inlet fitting is a 1/8-27 NPT. The preferred
method is to use steel adapter fittings at the caliper, either straight, 45 or 90 degree and enough steel braided line to allow for full
suspension travel and turning radius, lock to lock. Carefully route hoses to prevent contact with moving suspension, brake or
wheel components. NOTE: Wilwood hose kits are designed for use in many different vehicle applications and it is the installer's
responsibility to properly route and ensure adequate clearance and retention for brake hose components. Wilwood includes a brake flex
line hose kit with this brake kit, P/N 220-12092. Hose kits include hoses, fitting, etc., all in one package for this application.
•NOTE: Specified brake hose kits may not work with all Years, Makes and Models of vehicle that this brake kit is applicable to, due to
possible OEM manufacturing changes during a production vehicle's life. It is the installer's responsibility to ensure that all fittings and
hoses are the correct size and length, to ensure proper sealing and that they will not be subject to crimping, strain and abrasion from
vibration or interference with suspension components, brake rotor or wheel.
•In absence of specific instructions for brake line routing, the installer must use his best professional judgment on correct routing and
retention of lines to ensure safe operation. Test vehicle brake system per the 'minimum test' procedure stated within this document
before driving. After road testing, inspect for leaks and interference. Initially after install and testing, perform frequent checks of the
vehicle brake system and lines before driving, to confirm that there is no undue wear or interference not apparent from the initial test.
Afterwards, perform periodic inspections for function, leaks and wear in a interval relative to the usage of vehicle.
• Bleed the brake system, referring to the additional information and recommendations on page 6 for proper bleeding instructions. Check
system for leaks after bleeding.
• Install the wheel and torque lug nuts to manufacturer’s specifications.

Balancing the Brake Bias on 4 Wheel Disc Vehicles
•OE Style or Single Mount Race Pedal with Tandem Outlet Master Cylinder:
Front to rear caliper piston sizes, rotor diameters, and pad compounds must be initially configured to provide the correct range of vehicle
bias when using a single bore / tandem outlet master cylinder. If excessive rear brake bias is experienced, an in-line adjustable
proportioning valve can be used to decrease the rear line pressure to help bring the vehicle into balance. If excessive front brake bias
is experienced, first consideration should be given to increasing the rear brake bias to bring the vehicle into overall balance.
•Race Pedal with Dual Master Cylinders and Balance Bar:
Master cylinders must be sized to match the calipers and allow the pedal balance bar to operate near the center of its travel. If it is not
possible to fine tune the bias within the adjustable range of the balance bar, then consideration must be given to changing a master
cylinder bore size or some other aspect of the brake system to bring the car into balance. Larger bore master cylinders will generate
less pressure while decreasing pedal travel. Smaller bores master cylinders will generate higher line pressures with an increase in pedal
travel.
