DISC BRAKE ASSEMBLY INSTALLATION
1.
In order to measure the brake drag force after pad
installation, measure the rotary-sliding resistance of the
hub by the following procedure with the pads removed.
(1) Withdraw the drive shaft. (Refer to GROUP 26 – Front
Axle.)
(2) Attach the special tool to the front hub assembly as
shown in the illustration, and tighten it to the specified
torque.
Tightening torque: 196 – 255 Nm
(3) Use a spring balance to measure the rotary-sliding
resistance of the hub in the forward direction.
2.
Install the caliper support to the knuckle, and then assemble
the pad clip and the pad to the caliper support.
Caution
Do not contaminate the friction surfaces of the pads
and brake discs by any oil or grease.

3.
Clean the piston and insert it into the cylinder with the
special tool.
4.
Be careful that the piston boot does not become caught,
when lowering the caliper assembly and install the guide
pin to the caliper.
5.
Start the engine, and then depress the brake pedal two
or three times strongly. Then stop the engine.
6.
Turn the brake disc forward 10 times.
7.
Use a spring balance to measure the rotary-sliding
resistance of the hub.
8.
Calculate the drag force of the disc brake [difference
between the values measured at steps 1 and 7].
Standard value: 69 N
9.
If that drag force exceeds the standard value, disassemble
the piston assembly. Then check the piston for
contamination or rust, and confirm if the piston or the
piston seal is deteriorated, and if the lock pin and the
guide pin slide smoothly.
