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.
•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 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.
If the brake pedal goes to the floor and continued bleeding of the system does not correct the problem, a master cylinder with
increased capacity (larger bore diameter) may be required. Wilwood offers various lightweight master cylinders with large fluid
displacement capacities.
•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.
