REAR WHEEL BRAKE DRUM REMOVAL

∆
WARNING
• Use only approved replacement brake drums designed for your vehicle. For MC012C-AS00
transaxles, use CCI P/N 102264701.
1. Chock the front wheels, release the park brake, loosen the rear wheel lug nuts and lift the rear of the vehi-
cle with a chain hoist or floor jack. See WARNING "Lift only one end..." on page 1-2.
2. Place jack stands under the axle tubes and lower onto stands.
3. Remove the lug nuts and remove rear wheel.
4. Remove the brake drum. If the brake drum was easily removed, proceed to step 6.
5. To remove tight brake drums:
5.1. On the back of each brake cluster assembly, locate the bolt heads of the two brake shoe adjusters.
5.2. Use a torque wrench and a Torx #T-27 driver, or hydraulic brake adjuster (CCI P/N 102169401), and
gently rotate the adjuster bolts to increase the clearance between the brake shoe lining and the
brake drum (Figure 6-3, Page 6-7). See following NOTE.
NOTE: If the adjusters require more than 65 in-lb (7.3 N·m) of force to rotate, they must be replaced. See
Brake Shoe Adjuster Replacement on page 6-21.
5.3. Rotate the brake drum slightly to remove it.
6. Repeat steps 3 through 5 for the opposite rear wheel if necessary.

BRAKE SHOE REMOVAL

See General Warning, Section 1, Page 1-1.
∆
WARNING
• If at any point in this procedure the hydraulic system is opened, the brakes must be bled after
the correct reinstallation of the brake components. Failure to bleed the brakes could result in
decreased braking performance due to air being trapped in the hydraulic system. Use only
DOT 5 brake fluid. See Bleeding the Hydraulic Brake System on page 6-31.

FRONT BRAKE SHOE REMOVAL

1. Remove the brake drum. See Front Wheel Brake Drum Removal on page 6-6.
2. Use pliers or a brake tool to rotate the cup washer and compression spring assembly 90° and remove
the cup and spring from each brake shoe (Figure 6-4, Page 6-9). See following NOTE.
NOTE: The brake shoes are under spring tension and can release suddenly when cup and spring assem-
blies are removed.
3. Pull brake shoes and tensioning springs from the brake cluster assembly (Figure 6-7, Page 6-9).
4. Repeat steps 1 and 3 for the opposite front wheel if necessary.
