NOTICE


For more information regarding rear brake service, refer to the applicable vehicle shop manual.

1a.

When servicing rear brakes on vehicles
equipped with an Electronic Parking Brake
(EPB), the Brake Pad Change Mode function
must be performed to release the rear
calipers before the caliper is removed.

1b.

Disconnect the EPB actuator (A) before
removing the caliper from the bracket.

1c.

If replacing the pads, retract the caliper
piston by rotating it.

BRAKE SERVICE BEST PRACTICE RECOMMENDATIONS

Replace and reinstall parts in reverse order
of removal.

NOTICE
Tighten all bolts to the torque
specification recommended in the
appropriate vehicle shop manual.

Use the Brake Pad Change Mode in the
GDS-M to apply and release the EPB.
Repeat the apply/release function three
times.

1e.

After completing the Brake Pad Change
Mode, perform the Assembly Check (ECU
replacement) function.
Also perform this function after replacing the
rear pads, caliper, EPB actuator, or EPB
ECU.

2.

When servicing rear brakes on vehicles with
a manual parking brake, the piston may
need to be retracted by rotating the piston.

3.

When performing the brake service, always
remove, clean, and inspect the caliper slide
pins and boots.
Apply Silicone Paste, P/N 00232-19087 to
the caliper slide pins before reinstallation.

NOTICE





This procedure does not apply to
fixed-type calipers.
Use caliper slide pin recommended
lubricant.
Do not over-lubricate the slide pins.
If too much lubricant is applied to the
slide pins, air can be trapped at the
end of the pin creating an “air spring”.
This condition causes the caliper/pad
assembly to drag on the rotor.

CAUTION

Do not hang the caliper with the brake
hose.

BRAKE SERVICE BEST PRACTICE RECOMMENDATIONS

Remove the pads, and clean the pad backing plate and insulators/shims of debris.
Never reuse shims on new pads.
Inspect the pad friction surface for even wear and pad thickness. Refer to the applicable
vehicle shop manual for service limits.
Grease should not be applied to the pad backing plate unless instructed by the shop manual
or TSB(s), as it could trap debris, and increase the chance of noise or dragging.

5.

Remove the pad retainers, and clean the
contact surface of the caliper from debris
and corrosion. Use a wire brush if
necessary. Apply a light coat of Copper
Anti-Seize Brake Lube, P/N 00232-19086,
to prevent further corrosion (E).
Clean and inspect the retainers if the pads
are reused. Discard damaged retainers.
Always use the retainers included with the
new pads.

Inspect the caliper for brake fluid leaks.

If a fluid leak is found at the banjo bolt
area between the brake line and the
caliper, replace the copper washers on
the banjo fitting.

7.

When re-installing the brake pads, install the
pad with the wear indicator on the inside, as
shown.

8.

Tighten all bolts to the torque specification recommended in the appropriate vehicle
shop manual.

NOTICE


1.

Always follow the brake lathe manufacturer’s recommendations for proper machining.
For more information on brake drum service, refer to the applicable vehicle shop manual.
Measure the inside diameter and runout of
the drum BEFORE and AFTER machining to
ensure the brake rotor is within specification.



Refer to the applicable vehicle shop
manual for service limits.
When measuring the drum, remove all
surface contamination and corrosion to
ensure an accurate measurement.

2.

Clean all drum brake assembly components
to inspect for wear and leaks.

3.

Debris on the wheel cylinder and boots is not
an immediate indication that the wheel
cylinder is leaking. Carefully inspect the
wheel cylinder for leaks.

5.

Inspect the brake shoe springs. If any of the springs are broken, replace all brake shoe
springs.
During brake shoe replacement, it is also recommended to replace all shoe springs.

6.

Refer to the applicable vehicle shop manual
for locations regarding where to apply the
Copper Anti-Seize Brake Lube, P/N
00232-19086, to the contact/sliding points
between the shoes and brake components.

CAUTION

Prevent any grease from touching the
shoe lining or drum friction surfaces.

To set the rear drum to shoe running clearance, refer to the applicable vehicle shop manual.

8.

Tighten all bolts to the torque specification recommended in the appropriate vehicle
shop manual.

CAUTION
Do not reuse drained fluid.
Always use genuine DOT3 or DOT4 brake fluid as recommended in the applicable vehicle
shop manual. Using non-genuine DOT3 or DOT4 brake fluid can cause corrosion, and
can decrease the life of the system.
Verify dirt or other foreign matter does not contaminate the brake fluid.
Do not spill brake fluid onto the vehicle. This may lead to paint damage. If brake fluid
comes in contact with any paint surface, wash the surface off immediately with water.
When bleeding air, ensure that the fluid level never drops below halfway between MIN
and MAX in the reservoir.
Ensure that the brake fluid reservoir level
never drops below the halfway point
between MIN and MAX.
If the level drops below the halfway point, air
may be introduced into the system, and the
bleeding procedure must be restarted.

Ensure the fluid
level never drops
below halfway
between MIN and
MAX

NOTICE
Use genuine DOT 3 or DOT 4 brake
fluid as recommended in the applicable
vehicle shop manual
2.

Use a hose inserted into a partially filled
container of clean brake fluid to catch the old
brake fluid.

Brake Caliper Fluid Inspection


If fluid appears around the brake caliper piston area, test the fluid to identify whether the fluid is
brake fluid, or assembly oil per the service procedures below.

1.

If oil/fluid is present on the brake caliper
piston area, test the fluid to determine if it is
brake fluid or assembly oil.

2.

Use a cotton swab to carefully collect a
sample of the fluid.
Do not disturb the caliper boot.

BRAKE SERVICE BEST PRACTICE RECOMMENDATIONS

Using an oil or water based ink pen, draw
several horizontal lines on a sheet of paper.
Wipe the collected fluid vertically down the
ink lines.

4.

If the ink does not smear, the fluid is not
brake fluid and is likely to be assembly oil.
 Wipe the excess oil using a clean
shop towel.
 Do not disturb the caliper boot.
If the ink runs/smears, the fluid is likely to be
brake fluid.
 Continue to investigate and repair the
source of the brake fluid.
