General steps 
Removal and installation of wheels and tires  
1. This chapter does not include the removal and installation steps of wheels and tires. If necessary to remove the wheel, they shall be retightened up at the installation time, to the specified torque in 88-127N.m {9.0-13.0kgf.m,65-94ft.lbf}. 
Disconnection and connection of brake line Attention 
The brake fluid will damage the paint surface, thus, if the brake fluid stained the paint surface, please wipe it up immediately 
1. Use the SST(49 0259 770B ) to screw up the flare nut of brake line, the tightening torque of flare nut on the brake line has to be adjusted to match with the use of combination tool——joint torque wrench -SST(See——Moment Equation G1). 
2. If the brake line used to be disconnected during the operation, the brake fluid shall be added, air in the brake system exhausted, then check for any system leakage after the completion of work. 
Disconnection of plug  Attention 
1.  Prior to the connector operation, the negative connection of battery shall be disconnected, the negative connection can be remade up only after the completion of work. 
Precautions to the operation of ABS control unit component  
1. After the work of ABS control unit component completed, no fault codes shall exist in the ABS control unit system. If there are fault codes in the diagnostic system, eliminate them(See——Fault Diagnostic Function, ABS Control Unit System, steps to clean up the fault codes). 

Conventional brake system Air exhaust 
Whenever, the brake system shall exhaust, when the brake line disconnected. If the hydraulic piping is disconnected at the brake master cylinder, the braking shall exhaust by starting from the farthest slave cylinder, and then further wheel cylinder until the exhaust of four sub-cylinders completed. If the point of disconnection is not located at the brake master cylinder, then the exhaust shall start from the nearest disconnection point from the brake slave cylinders, and then the further wheel cylinder until the exhaust braking 4 of cylinders completed.
Standard of brake fluid:  
1.Shore up with a jack a vehicle on a level ground and hold the vehicle on a safe platform. 
2.Remove the exhaust valve cap from the calipers and fit up a vinyl pipe, transparent and not corroded by brake fluid on the exhaust bolt. 
3.Place another end of plastic pipe in a clean fluid container. 
4.The operator A steps down the brake pedal several times, and then hold it on the depressed position. The operator B unscrews the exhaust bolt, drains the liquid, the operator A may release the brake pedal, after the bleed bolt has been retightened by the operator B with SST. 
5.Repeat the steps 4 and 5 until bubbles appear again. 
6.During the air exhaust process, the fluid reservoir shall be held at the 3/4 liquid level to prevent air reentry again into the pipe. 
Tightening torque: 5.9-8.8N·m (60-90kgf·cm)
