Wilwood W4A Big Brake Front Brake Kit (Race) - Manual (Page 5)

Assembly Instructions (Continued)
•Specified brake hose kits are based on production based vehicles. They may not work with all models or custom built vehicles using
production Corvette suspension components. 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 rotors, or wheels. Carefully route the lines to prevent contact with these or any other elements
that could cause damage to the lines.
•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. Confirm that there is no undue wear or interference between the lines and any element
of the chassis or suspension. Afterwards, perform periodic inspections for function, leaks and wear in a interval relative to the usage
of vehicle.
Bleed the Brake System
•First, reference the manufacturer’s service manual for the proper flushing and bleeding procedures for your vehicle, and then consult
the additional information and recommendations below for proper bleeding instructions.
•Fill and bleed the system with Wilwood EXP 600 Plus Racing Brake Fluid from a new bottle. Used fluid must be completely flushed
from the system to prevent contamination.
•NOTE: Silicone DOT 5 brake fluid is NOT recommended for racing or performance driving.
•To properly bleed the brake system, begin with the caliper farthest from the master cylinder. Bleed the outboard bleed screw first, then
the inboard. Repeat the procedure until all calipers in the system are bled, ending with the caliper closest to the master cylinder.
•NOTE: When installing a new master cylinder, it is important to bench bleed the master cylinder first.
•Test the brake pedal.
It should be firm, not spongy and stop at least 1 inch from the floor under heavy load. If the brake pedal is spongy, bleed the system
again.
If the brake pedal is initially firm, but then sinks to the floor, check the system for fluid leaks. Correct the leaks found and then bleed
the system again. Do not attempt to test or drive the car until a firm pedal has been established.
Finishing the Installation
•NOTE: With the installation of after market disc brakes, the wheel track and/or wheel clearance may change depending on the
application. Check your wheel offsets and clearances before final assembly. Do not operate any vehicle if there is interference between
any part of the wheel, brake caliper, or suspension component.
•Remove the lug nuts that were holding the hat in place. Install the wheel and torque the lug nuts to specification.
•Repeat this entire procedure for the other wheel.
•If after following the instructions, you still have difficulty in assembling or bleeding your Wilwood disc brakes, consult your local chassis
builder, or retailer where the kit was purchased for further assistance.
