How to replace the front Brake Disc on a with RPO LNF (2.0L) on 2009 Chevrolet Cobalt?

To replace the front Brake Disc on a vehicle with the rpo lnf (2.0), first raise and support the vehicle, then remove the tire and wheel assembly. Then, take off the brake caliper bolts and unpoke the brake caliper assembly from the Steering Knuckle, suspending it with heavy mechanic wire to avoid damaging the hydraulic flexible brake hose. Mark the position of Brake Disc with regards to wheel studs and after that remove and throw away Brake Disc retainers, if provided, then after that put off and discard the disc Brake Disc. Clean rust or any contaminations from the hub/axle flange with the j 42450-a and the Brake Disc with j 41013. Examine the mating surfaces for any presence of debris. Mount the Brake Disc onto the hub with the matchmark to ensure proper installation. If disc was a part of the brake system repair, measure the assembled lateral runout (LRO) to guarantee its optimal operation. If this is more than the specifications, correct it as well. Clean the threads of the bolts of the rear calipers and the mounting holes of the knuckles with denatured alcoholic material, then add thread locker gm p/n 12345493 (Canadian P/N 10953488) to 2/3 of the threaded length of the caliper bolts, without leaving any gaps. Let the threadlocker sit for about 10 minutes and you can install the brake caliper assembly to the Steering Knuckle and torque the brake caliper bolts to 130 nm (96 lb ft). Lastly, reinstall the tire and wheel assembly.
