Workpiece (Rotor) Preparation
Workpiece (Rotor) Preparation
Clean the workpiece thoroughly with non-petroleum based,
evaporating cleansers or warm soapy water .
Remove all rust and corrosion from the mounting surfaces of the
workpiece and vehicle hub by using emery paper, Scotch-Brite
abrasive, or an electric hand drill equipped with a wire brush
attachment .
Do not blow or breathe dust from the brake lathe.
Always use proper caution and protection while
performing brake maintenance.
Twin Cutter Insert Holder Installatio
Twin Cutter Insert Holder Installatio
The twin cutter insert holders can be installed two different ways as
shown by the pictures below .
Recommended Insert Holder Installation -
Standard Rotation
The picture below shows the recommended installation for standard
rotation . This set up has a maximum rotor width at the edge of
41 .275 mm (1 .625 in . ) . It is recommended to work best for the
majority of rotors . The maximum friction pad surface thickness in
this set up is 69 .85 mm (2 .75 in) .
Pay attention to the difference in the depth that the two holders are
installed on the twin-cutters .

Alternative Insert Holder Installation -
Standard Rotation
The picture below shows the optional installation method for
standard rotation allowing for a maximum rotor pad surface width of
76 .2 mm (3 .00 in . ) . This setup should only be used on rotors that are
thicker than 41 .275 mm (1 .625 in . ) at the edge .

Install the bits in the bit holders using the small Torx wrench
included .

Recommended Insert Holder Installation -
Reverse Rotation
Reverse rotation is used on some vehicles when excess drag on the
vehicle drivetrain prevents normal ACE operation .
The twin cutter insert holders must be flipped over when using the
reverse function .
Image 16.
The picture below shows the recommended installation for reverse
rotation . This set up has a maximum rotor width at the edge of
41 .275 mm (1 .625 in . ) . It is recommended to work best for the
majority of rotors . The maximum friction pad surface thickness in
this set up is 69 .85 mm (2 .75 in . ) .
Pay attention to the difference in the depth that the two holders are
installed on the twin-cutters .

Overview
1 .
Always perform a thorough brake and vehicle inspection
prior to any service . Measure rotor thickness and compare
to specification . If the before and after thickness is within
acceptable range, proceed with resurfacing .
2 .
Inspect the lathe . Check the condition and tightness of the
cutting inserts .
3 .
Select the proper hub flange adaptor to fit on vehicle's rotor .
4 .
Verify that all mounting areas are clean .
5 .
Mount the hub flange adaptor to the rotor . Secure the hub
flange adaptor to the rotor face by using the vehicle's lug nuts
or the nuts provided in Kit 20-1503-1.
6 .
Mount the universal hub adaptor to the hub flange adaptor (if
required) .
7 .
Mount the lathe to the universal hub adaptor . Tighten .
8 .
Perform automatic compensation adjustment .
9 .
Position the twin cutter to correctly machine the rotor surfaces .
10 . Begin turning rotor at a moderate RPM (around 50-60 RPMs) .
Position the cutting inserts at the inner diameter of the rotor's
inboard and outboard friction surfaces .
11 . Adjust the cutting inserts for the desired depth of cut .
12 . Engage the feed mechanism .
13 . Adjust the RPMs to the desired level, engage the ACT if
desired, and machine the rotor surface .
14 . After the desired level of cut and finish has been achieved,
remove the lathe and adaptors from the vehicle . Clean lathe of
debris .
15 . Clean rotor according to Original Equipment Manufacturer
(OEM) recommended procedure and assemble brake system .
16 . Reinstall the wheel/tire assembly and secure with lug nuts
installed to the proper torque specifications for the vehicle .
17 . Repeat procedure on other rotors as required .
B) Hub flange adaptor
D) Insert holder with micro-round
cutting inserts
