Here's a general guide. Consult a repair manual specific to your 2000 Oldsmobile Alero for precise instructions and torque specifications. Improper torque can lead to brake failure.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safety.
* Lug wrench: To remove the wheels.
* Wheel chocks: To prevent the car from rolling.
* Sockets and wrenches: Various sizes, likely including those for the caliper bolts, parking brake adjuster, and possibly the axle nut (if the rotor is part of an integrated hub assembly).
* Hammer and punch (possibly): To help break free any rusted or seized components.
* C-clamp or brake caliper compression tool: To compress the caliper pistons.
* Penetrating oil (PB Blaster or similar): To loosen rusted bolts.
* Torque wrench: Crucial for tightening bolts to the correct specification.
* Gloves and safety glasses: Protect yourself.
Procedure (General - Consult your repair manual for specifics):
1. Safety First: Engage the parking brake, chock the front wheels, and securely lift the rear of the vehicle using the jack. Place it on jack stands.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Release the Parking Brake: Locate the parking brake mechanism (usually a cable connected to a lever or adjuster on the back of the backing plate). This will need to be released or loosened to allow the rotor to be removed. The exact procedure will depend on the design of your parking brake. A repair manual will show you how.
4. Remove the Caliper: Using the appropriate socket, remove the bolts holding the caliper to the backing plate. Carefully remove the caliper and hang it out of the way using a wire or bungee cord. Do not let the brake line hang freely; support it to prevent damage or leakage.
5. Compress the Caliper Pistons: Using a C-clamp or specialized tool, compress the caliper pistons to make room for the new rotor. Be prepared for some resistance; use a firm, even pressure.
6. Remove the Rotor: Depending on your Alero's configuration, the rotor may slide off, or it might be secured to the wheel hub with bolts or a nut on the axle. If there are bolts, remove them. If there's an axle nut, loosen it carefully. If the rotor is seized, you may need a hammer and punch (gently) to help it free.
7. Clean and Inspect: Once the rotor is off, inspect the wheel hub, backing plate, and brake components for wear or damage. Clean any rust or debris.
8. Installation: The installation is the reverse of the removal process. Remember to properly lubricate any sliding surfaces.
9. Torque Specifications: Tighten all bolts and nuts to the manufacturer's specified torque using a torque wrench. Incorrect torque can damage components or lead to brake failure.
Important Considerations:
* Rust: Older vehicles often have rusted components. Penetrating oil is your friend. Apply it liberally to bolts and other connections well in advance of starting the job to allow it to penetrate.
* Brake Fluid: If you need to bleed the brakes after working on the system, refer to your repair manual for the proper procedure.
* Hub Assembly: Some vehicles have an integrated wheel hub and rotor. If this is the case, the process might be more complex, potentially requiring a wheel bearing press to install the new assembly.
This is a general guide. Without a repair manual specific to your 2000 Oldsmobile Alero, you risk damaging components or causing injury. Always consult a repair manual or seek professional help if you're not comfortable performing this task.
