Pad assembly
Apply repair kit grease to both sides of the inner shims.
Specified grease: Brake grease SAE
Caution
1. Make sure that the friction surfaces of pads and
brake discs
free of grease and other contami-
nants.
2. The grease should never squeeze out from around
the shim.
9.
Check the disc brake drag force as follows.
(1) Start the engine, and after depressing the brake pedal
hard two or three times, stop
(2) Turn brake disc forward
engine.
(3) Use a spring balance to
Sliding re-
sistance of the hub in the forward direction.
(4) Calculate the drag torque of the disc brake (difference
between measured values in 3 and 4).
Standard value: 70 (15.4
or less
10. If the disc brake drag force exceeds
standard value,
disassemble piston and clean the piston. Check for corro-
sion or worn piston seal, and check the sliding condition of
the lock pin and guide pin.
FRONT DISC BRAKE ROTOR INSPECTION
CAUTION
When servicing disc brakes, it is necessary to exercise caution to keep the disc brakes within the
allowable service values in order to maintain normal brake operation.
Before re-finishing or re-processing the brake disc surface, the following conditions should be checked.
Inspection items
Remarks
Scratches, rust, saturated lining materials
and wear
l
If the vehicle is not driven for a certain period, the sections of the discs
that are not in contact with lining will become rusty, causing
noise and
shuddering.
l
If grooves resulting from excessive disc wear and scratches are not re-
moved prior to installing a new pad assembly, there will momentarily
be inappropriate contact between the disc and the lining (pad).
or drift
in thickness (parallelism)
Excessive run-out or drift of the discs will increase the pedal depression
resistance due to piston knock-back.
If the thickness of the disc changes, this will cause pedal pulsation, shud-
dering and surging.
