Wilwood Tandem Master Cylinder - Manual

Installation Notes and Precautions
•
Always mount the master cylinder to a secure, reinforced element of the chassis. There should be no movement or deflection at the mount
point when brake pedal pressure is applied. When using fabricated mounts or pedal linkages, it is important that the alignment of the push
rod and piston are kept as straight as possible to prevent side loading the piston against the master cylinder bore
•
Be sure the pedal and push rod are adjusted to allow the master cylinder piston to fully retract against the snap ring at the back of the master
cylinder bore when the pedal is fully retracted. There should also be adequate pedal travel to fully compress the master cylinder. Pedal return
springs and stops are highly recommended.
•
Prior to attaching the fluid lines, fill the reservoirs with Wilwood fluid from a new, sealed container and purge any air from the master cylinder.
Be sure the cylinder is level during the bleeding operation. If the cylinder is not level when mounted in the vehicle, you can perform this
operation prior to attaching the master cylinder to its mount. The diagram illustrates one method of recycling the fluid into the reservoir until
all air has been eliminated. Exercise care to not spill or spray brake fluid. Take all proper safety precautions including eye and skin protection
and do not position your face directly above the
reservoir. This process will assure a quick and effective
full system bleed later.
•
Once all fluid connections have been made, the
complete system must be bled and checked for leaks
prior to any test of the vehicle.
Plumbing Notes and Precautions
•
Flare nuts to fabricate double flared 3/16" diameter
brake lines are included with each master cylinder. Use
only double flared lines. Do not attempt to use single
flared connections. Standard automotive double flared
lines with the correct size fittings can also be
purchased pre-made from an auto parts store.
•
Use of reinforced flexible lines should be limited to the
connection between the fixed chassis and the moving
suspension. All other lines along the fixed chassis
should be hard steel lines.
