Installing the Disc Brake Assembly (front brake)
To measure the rotational resistance force after installing the brake pads, first measure the rotational resistance of the wheel bearing with the brake pads removed.
Remove the wheel drive shaft.
Install the special tool on the front wheel hub assembly as shown in the figure and tighten it to the specified torque.
Tightening torque: 196–255 Nm.
Use a spring dynamometer to measure the resistance to rotation of the wheel bearing with the brake pads removed (in forward direction).
Rear brake
Use a spring dynamometer to measure the resistance to rotation of the wheel bearing with the brake pads removed (in forward direction).
After installing the caliper on the steering knuckle, install the shoe guides and shoes on the caliper bracket.
Attention! Do not allow oil, grease or other foreign material to contaminate the brake disc or friction surfaces of the pads.
Clean the piston and insert it into the cylinder with the special tool.
Be careful not to bite the piston guard when lowering the caliper assembly, and tighten the guide pin to the specified torque.
Tightening torque: 74 Nm.
Start the engine and then depress the brake pedal 2-3 times.
Stop the engine.
Rotate the brake disc forward 10 times.
Use a spring dynamometer to measure the resistance to rotation after installing the brake pads (in forward direction).
Calculate the increase in resistance to rotation.
Rated value: 69 N or less.
If the increase in resistance to rotation exceeds the nominal value, disassemble the piston and clean it. Check it for corrosion or wear on the piston cup, and check that the upper and lower guide pins move smoothly.
