INSTALLATION SERVICE POINT
"AADISC 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, 27.)
(2) Attach the special tool to the front hub assembly as
shown in the illustration, and tighten it to the specified
torque.
Tightening torque:
245±29 N·m , 225±25 N·m
(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 and the clip 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 in the forward direction.
8. Calculate the drag force of the disc brake [difference
between the values measured at steps 1 and 7].
Standard value:
51 N or less , 69 N or less
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 slide pins slide
smoothly.
1. Find the drag force of the disc brake. (Refer to P.35A-13.)
Standard value: 69 N or less
2. 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.MB990998

Caution: Brembo disc brake
Take care not to contact the parts or tools to the caliper
because the paint of caliper will be scratched. And if
there is brake fluid on the caliper, wipe out quickly.
AA"PISTON BOOT/PISTON REMOVAL
Remove the piston boot by pumping in air slowly from the
brake hose connection. Be sure to use the handle of a plastic
hammer and adjust the height of the two pistons while so
that the pistons protrude evenly.
Caution
Do not remove one piston completely before trying to
remove the other piston, because it will become
impossible to remove the second piston.
Use a piece of wood to protect the caliper body outer side,
and then apply compressed air through the brake hose
connection hole to withdraw the piston and piston boot.
Caution
If air is blown into the caliper body suddenly, the piston
will pop out, causing damage to the caliper body. Be
sure to apply compressed air gradually.
AB"PISTON SEAL REMOVAL
1. Remove the piston seal with finger tip.
Caution
Do not use a flat-tipped screwdriver or other tool to
prevent damage to inner cylinder.
2. Clean piston surface and inner bore with trichloroethylene,
alcohol or the specified brake fluid.
Specified brake fluid: DOT3 or DOT4
