Every automobile's brake system includes front and rear rotors. Brake rotors are made from iron and look like discs. These discs are actually what the brake pads grip and stop every single time you step on the brake pedal. An effective brake system is probably the most important part of any motor vehicle. Nothing is more important than the ability of the car to stop whenever necessary. This is why preventive maintenance should always be performed if you want to make sure that your car's brake system, including the rear rotors, are in no way compromised.
- Get yourself acquainted with the signs of rear rotor wear. A good rule of thumb would be to replace the worn out parts such as rear rotors at least once every two years. But of course, this will only apply if you do not use your car to carry huge heavy loads frequently. If you hear a distinct metal scraping sound whenever you step on the brake pedals, then it's high time you inspect your car's brake system for wear and tear of its components.
- Park the car in the correct spot. Not only should you consider parking your car in a shady spot but an even surface as well. You would not want to end up having your car roll on you just because you failed to park it properly.
- Perform all the necessary safety measures to avoid accidents. Firstly, wear eye protective gear. Next, set the car's hand brake. And while you're at it, turn off the engine as well.
- Prepare the car. Firstly, loosen the lug nuts holding the wheel secure with the use of appropriate tools. Prop up the car's rear end using two sturdy jack stands. Finally, pull out the rear tires. Also, you will need to remove the cap of the container holding the brake fluid. Place a clean bucket underneath the car to catch brake fluid that may spill during the process.
- Uninstall the necessary brake components. Brake calipers should be loosened and hung on the suspension arm using a sturdy wire. Next is to unscrew the bolts holding the brake rotor to remove it.
- Put in the replacement rear rotors. New rotors have protective paint coating which should be removed before fitting. Once clean, apply liberal amounts of grease onto the back part of the rotor so as to prevent rust from accumulating once it's attached to the brake system. Slide in the replacement rear rotor and secure with bolts. Undo the wire holding the caliper to position it properly and screw the caliper back on.
Now that you're done changing the rear rotors, all that's needed is to re-install the tires and secure them with lug nuts. Do this by letting the car rear down to take out the jack stands. Make sure to check if the wheel lug nuts are properly tightened. Test your car by driving it slowly around the block.
