from the vehicle.

OVERHAUL

Wheel cylinder overhaul kits may be available, but often at little or no savings over a reconditioned wheel
cylinder. It often makes sense with these components to substitute a new or reconditioned part instead of
attempting an overhaul.
If no replacement is available, or you would prefer to overhaul your wheel cylinders, the following procedure
may be used. When rebuilding and installing wheel cylinders, avoid getting any contaminants into the system.
Always use clean, new, high quality brake fluid. If dirty or improper fluid has been used, it will be necessary
to drain the entire system, flush the system with proper brake fluid, replace all rubber components, then refill
and bleed the system.
1. Remove the wheel cylinder from the vehicle and place on a clean workbench.
2. First remove and discard the old rubber boots, then withdraw the pistons. Piston cylinders are
equipped with seals and a spring assembly, all located behind the pistons in the cylinder bore.
3. Remove the remaining inner components, seals and spring assembly. Compressed air may be useful in
removing these components. If no compressed air is available, be VERY careful not to score the
wheel cylinder bore when removing parts from it. Discard all components for which replacements
were supplied in the rebuild kit.
