rotor does not require any servicing, install caliper
assembly.
(11) Install brake hose onto caliper using banjo
bolt. Torque the brake hose to caliper assembly banjo
bolt to 33 N·m (24 ft. lbs.). New seal washers
MUST always be used when installing brake
hose to caliper.
(12) Bleed the brake system (see Bleeding Brake
System).
CLEANING AND INSPECTION
BRAKE TUBES AND HOSES
Flexible rubber hose is used at both front and rear
brakes. Inspection of brake hoses should be per-
formed whenever the brake system is serviced and
every 7,500 miles or 12 months, whichever comes
first (every engine oil change). Inspect hydraulic
brake hoses for severe surface cracking, scuffing,
worn spots or physical damage. If the fabric casing of
the rubber hose becomes exposed due to cracks or
abrasions in the rubber hose cover, the hose should
be replaced immediately. Eventual deterioration of
the hose can take place with possible burst failure.
Faulty installation can cause twisting, resulting in
wheel, tire, or chassis interference.
The steel brake tubing should be inspected period-
ically for evidence of corrosion, physical damage or
contact with moving or hot components of the vehi-
cle.
DISC BRAKES (FRONT)
BRAKE SHOE (PAD) LINING WEAR
If a visual inspection does not adequately deter-
mine the condition of the lining, a physical check will
be necessary. To check the amount of lining wear,
remove the wheel and tire assemblies, and the cali-
pers.
Remove the front disc brake shoes. Refer to Front
Disc Brake Shoe Removal in the Removal And Instal-
lation section in this group of the service manual for
the required procedure.
The combined brake shoe and lining material
thickness should be measured at the thinnest part of
the assembly.
When a set of brake shoes are worn to a total
thickness of approximately 6.5 mm (1/4 inch), they
should be replaced.
Replace both brake shoe assemblies (inboard and
outboard). It is necessary that both front wheel sets
be replaced whenever brake shoe assemblies on
either side are replaced.
If the brake shoe assemblies do not require
replacement, reinstall, the assemblies making sure
each brake shoe is returned to the original position.
Refer to Front Disc Brake Shoe Installation in the
Removal And Installation section in this group of the
service manual for the required procedure.
CALIPER INSPECTION
Check for brake fluid leaks in and around boot
area and inboard lining, and for any ruptures, brit-
tleness or damage to the piston dust boot. If the boot
is damaged, or a fluid leak is visible, disassemble cal-
iper assembly and install a new seal and boot, and
piston if scored. Refer to Front Disc Brake Caliper in
the Disassembly And Assembly Section in this group
of the service manual.
Check the guide pin dust boots to determine if they
are in good condition. Replace if they are damaged,
dry, or found to be brittle. Refer to Front Disc Brake
Caliper in the Disassembly And Assembly Section in
this group of the service manual.

mine the condition of the lining, a physical check will
be necessary. To check the amount of lining wear,
