To change the front Brake Disc for a 1500 series vehicle, start out by checking the level of the brake master cylinder reservoir fluid. If the value happens to fall between the maximum and minimum values midway, then pull out fluid in order to provide such a value. Lift the car, and disconnect the tire and wheel assembly. If replacing the original Brake Disc, mark its relationship to the hub. Plug an empty fuel tank if not yet done, and then raise the car's front using the jack stands and arm the parking brake. Support the brake caliper using heavy mechanic wire to avoid the damage of a futuristic brake hose. Take out the brake caliper bolt and caliper as an assembly by removing the two mounting caliper bolts and then supporting the assembly with wire. Pull the Brake Disc retaining push nuts and the Brake Disc screw. Striking the disc with a deadblow hammer will cause the disc to vibrate and slip off the Wheel Hub. If the disc will not come off then clean the surfaces, apply penetrating oil, and start two m10 x 1.5 bolts into the disc's tapped holes then tighten it evenly to push the disc off. During installation, clean out the rust and contaminants from the hub flange using j-42450 -a (Wheel Hub Resurfacing Kit) and the interior diameter of the Brake Disc using j -41013 (Disc Resurfacing Kit). Clean the mating surfaces of the debris, align the disc with its original location, and fix it. Tighten the Brake Disc to 12 nm (106 Lb in) by screwing it, keeping in mind that a belt can be broken when the wrench stretches to adjust its depth with the rod. Replace the brake caliper and bracket, making sure to remove the old adhesive from the mounting bolts and clean the threads of the nuts, and apply a threadlocker gm p/n 12345493 (Canadian P/N10953488), and tighten the two mounting bolts to 200 nm (148 lb ft), as shown in fig. 1. Reattach the tire and wheel assembly, and then with the engine off, work up to about 2/3 pedal travel, release it slowly, and repeat until the pedal is firm. Make sure to fill the master cylinder reservoir with fresh brake fluid where necessary, and you burnish the
Brake Pads and discs if they were refinished or replaced.
