Voyager L4-156 2.6L SOHC (1984)
Maximum Single Cut
For best results in eliminating the irregularities that cause brake roughness and surge, the amount of material removed during a single cut should be
limited to 0.13mm (0.005 in.).
Final Cut
When the entire braking surface has been cleaned a final cut of 0.0254mm (0.001 in.) will assure a good drum surface providing the equipment
used is capable of giving the precision required for resurfacing brake drums.
-
Deeper cuts are permissible for the sole purpose of removing deep score marks.
CAUTION: Do not reface more than 1.52mm (0.60 in.) over the standard drum diameter.
NOTE: If one brake drum is machined, the other should also be machined to the same diameter to maintain equal braking forces.
After a brake drum is machined: Wipe the braking surface diameter with a cloth soaked in denatured alcohol.
