Additional Information and Recommendations:
•The pedal assembly uses standard racing master cylinder mounting patterns. Wilwood’s composite master cylinder and remote master
cylinder’s mount directly to the pedal assembly, as do most other high performance master cylinders. All master cylinder mounting hardware
is included with the pedal assembly. Master cylinder flange should mount flush to pedal assembly and be held in place with enclosed
washers and locknuts. The clevis on each pedal has a 5/16-24 thread. Make sure to use a jamnut on the master cylinder pushrod
when threaded into clevis and check that pushrod is allowed to fully retract when pedal is released.
•Wilwood Hi-Temp° 570 Racing Brake Fluid (P/N 290-0632) or other DOT 3, DOT 4 or DOT 5.1 brake fluid is recommended for race
cars and high performance vehicles where brake temperatures exceed normal operating conditions. NOTE: Silicone DOT 5 brake fluid
is NOT recommended for racing or performance driving.
•Adjust the balance bar so that the appropriate front to rear brake balance is achieved.
•If after following the instructions, you still have difficulty in assembling your Wilwood forward mount dual pedal assembly, consult your
local chassis builder, or retailer where the component was purchased for further assistance.
Additional Information and Recommendations
Brake Testing and Pad Bedding
PAD BEDDING PROCEDURE:
•Pump brakes at low speed to assure proper operation. On the race track, or other safe location, make a series of hard stops until some
brake fade is experienced. Allow brakes to cool while driving at moderate speed to avoid use of the brakes. This process will properly
burnish the brake pads, offering maximum performance.
• Make sure pedal is firm: Hold firm pressure on pedal for several minutes, it should remain in position without
sinking. If pedal sinks toward floor, check system for fluid leaks. DO NOT drive vehicle if pedal does not stay firm
or can be pushed to the floor with normal pressure.
• At very low speed (2-5 mph) apply brakes hard several times while turning steering from full left to full right, repeat
several times. Remove the wheels and check that components are not touching, rubbing, or leaking.
• Carefully examine all brake components, brake lines, and fittings for leaks and interference.
• Make sure there is no interference with wheels or suspension components.
• Drive vehicle at low speed (15-20 mph) making moderate and hard stops. Brakes should feel normal and
positive. Again check for leaks and interference.
• Always test vehicle in a safe place where there is no danger to (or from) other people or vehicles.
• Always wear seat belts and make use of all safety equipment.
WARNING • DO NOT DRIVE ON UNTESTED BRAKES
BRAKES MUST BE TESTED AFTER INSTALLATION OR MAINTENANCE
