How do I inspect and replace the brake discs?

To inspect the brakes, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the wheel and install the lug nuts to hold the disc in place. Then, remove the brake caliper, suspending it out of the way with wire. If working on a front disc, remove the caliper mounting bracket as well. Visually inspect the disc surface for score marks and damage, and check for disc runout using a dial indicator. If necessary, refinish the disc. Make sure not to machine the disc below the specified minimum thickness. To remove the disc, remove the lug nuts or disc retaining screws and free the disc from the hub. If stuck, use bolts to loosen it. When installing the new disc, secure it with retaining screws. Install the caliper mounting bracket and caliper, tightening the bolts properly. Finally, install the wheel, lower the vehicle, and tighten the lug nuts. Test the brakes before driving.

Saturn LS1 Brake Disc

The Brake Disc is a part of Saturn LS1 car's disc brake assembly that gives the brake pad the required surface to cause the slowing or stopping of the vehicle. Attached to the axle or hub, the rotor turns with the wheel; pressed against the rotor by hydraulic pressure that comes from the calipers are the pads when it is time to brake. Brake Discs fitted to Saturn LS1 cars may bring in different styles of rotors such as the solid and the vented styles of the rotors. Newer designs such as vented rotors with those protrusions called cooling fins help to dissipate heat more than the plain or solid rotors which are fitted on non-performance or small cars. Iron is commonly used for fabrication of most rotors, but they may sometimes use some composite materials to enhance their performance. Daily check and balanced are crucial, because rotors might have such defects as scoring, warping and high runout that decrease the braking force. There is often the advice to replace worn down rotors in pairs, for better operation of the vehicle.
