Wilwood Promatrix Front Replacement Rotor Kit - Manual (Page 4)

Additional Information and Recommendations
•Fill and bleed the new system with Wilwood Hi-Temp° 570 grade fluid or higher. For severe braking or sustained high heat operation,
use Wilwood EXP 600 Plus Racing Brake Fluid. 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.
•Properly bleed the brake system according to the vehicle manufacturer’s instructions, generally beginning with the caliper farthest from
the master cylinder. NOTE: When using 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 (if applicable) and
then bleed the system again.
•NOTE: With the installation of after market disc brakes, the wheel track may change depending on the application. Check your wheel
offset before final assembly.
•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.
Assembly Instructions (Continued)
• Temporarily install the wheel and torque the lug nuts to the manufacturer’s specification. Ensure that the wheel rotates freely without
any interference.
•Remove the OE rubber brake hose from the caliper to the hard line, being careful to keep fluid spillage to a minimum. Install Wilwood’s
stainless steel braided flexline hose kit, P/N 220-12336 included with this kit. Carefully route hoses to prevent contact with moving
suspension, brake or wheel components.
•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 below for proper bleeding instructions. Check
system for leaks after bleeding.
•Install the wheel and torque the lug nuts to manufacturer’s specifications.
