(4) Use a spring scale 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:
<Front

−2.4L engine> 54 N (12 pounds) or less

<Front

−3.8L engine> 64 N (14 pounds) or less

<Rear> 54 N (12 pounds) or less

6. 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.
