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 LS Brake Disc

The Brake Disc in the Saturn LS vehicles as is the case with most Disc Braked Vehicles is a component that is tasked with the responsibility of creating the necessary friction needed to bring the vehicle to a stop. Usually cast from gray iron, such discs can have the cooling fins on their outer face to improve heat dissipation, necessary for effective brake operation. In the case of Saturn LS models, several types of Brake Discs may be used; one is the solid while the other is the vented type known to offer enhanced cooling through exposure of the discs to air. A variation from the normal design includes drilled or slotted Brake Discs which provide better heat conductivity and reduced noise at the cost of increased wear of the pad. Maintenance of the Brake Discs in Saturn LS vehicle is crucial since Brake Discs may appear warped, cracked or rusty which affect the vehicle's braking system. Proper inspection and timely replacements of the brake discs pose as one of the ways that can help in maintaining the right braking mechanism of Saturn LS models.

Each OEM Saturn LS Brake Disc we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
