REMOVAL SERVICE POINT
<<A>> BRAKE DISC REMOVAL

AC208364 AB

Bolts
(M8×1.25)

If the brake disc is seized, install a M8 x 1.25 bolts as 
shown, and remove the disc by tightening the bolts 
evenly and gradually.

INSTALLATION SERVICE POINTS
>>A<< PIN BOOT INSTALLATION

AC209151AB

19 mm deep
socket

Pin boot

Knuckle

Use a 19-mm deep socket to press the pin boot into 
the knuckle.

>>B<< BRAKE CALIPER ASSEMBLY 
INSTALLATION

AC208291AB

1. In order to measure the brake drag torque, 

measure the hub torque with the pads removed by 
the following procedure.
(1) Use a spring balance to measure the hub 

torque in the forward direction.

(2) Record hub torque with pads removed.

CAUTION

Do not let any oil, grease or other contamination 
get onto the friction surfaces of the pads and 
brake discs.
2. Assemble the pad and wear indicator assembly, 

the pad clip and the shim to the knuckle, and then 
the outer pad and shim to the caliper body.

3. Install the caliper assembly, being careful not to 

pinch the piston boot.

>>C<< LOCK PIN/GUIDE PIN 
INSTALLATION

AC208319AB

Bleeder 
screw

Guide pin

Lock pin

Install the lock pin to the bleeder screw side of the

2. Twist the brake hose towards the lesser torsion 

between the brake hose and bracket as shown 
and secure it to the bracket.

>>E<< BRAKE DRAG FORCE CHECK

1. Check the brake drag force as follows.

(1) Start the engine and hold the brake pedal 

down for 5 seconds. (Pedal depression force: 
approximately 200 N)

(2) Stop the engine.
(3) Turn the brake disc forward 10 times.

AC208292AB

(4) Use a spring balance to measure the hub 

torque with pads installed in the same 
direction as earlier.

(5) Calculate the drag force of the disc brake 

[difference between hub torque with pads 
installed and hub torque with pads removed].

Standard value: 46 N or less

2. If the brake drag force exceeds the standard 

value, disassemble and clean the piston. Check 
for corrosion or worn piston seal, and check the 
sliding condition of the lock pin and guide pin.
