A.
Grooves should be further cleaned with a wire brush mounted on an air/electric drill motor. Use Kent Moore Tool J-39495-3 (or
equivalent). After this, use a "seal pick" or a small screwdriver to scrape any remaining scale from the edges of the grooves. (See Figure 3).
B.
Bores should be further cleaned with a 7/8" flex hone mounted on an air/electric drill motor. Use Kent Moore Tool J-39495-2 (or
equivalent). Use brake fluid as a honing fluid. DO NOT USE ANY PETROLEUM BASED FLUIDS. THEY ATTACK RUBBER USED
ON THE CALIPER (See Figure 4).
NOTICE:
After brushing and honing, THOROUGHLY FLUSH the housing bores and grooves with brake parts cleaner to remove any grit remaining. The
inboard grooves are not as accessible for flushing as the outboard grooves. Extra care MUST be used in flushing these areas completely. When
finished, wipe with a clean cloth or paper towel to assure no grit remains.
