Here's a general procedure. Specifics might vary slightly depending on your exact S-10 model and brake configuration.
Tools You'll Need:
* Jack and jack stands: Absolutely essential for safety. Never work under a vehicle supported only by a jack.
* Lug wrench: To remove the wheel.
* Wheel chocks: To secure the other wheels.
* Hammer: Possibly needed to loosen the rotor.
* C-clamp or rotor puller: Highly recommended to avoid damaging the rotor or hub. A C-clamp is often sufficient.
* Sockets and wrench: Appropriate size for your lug nuts and caliper bolts. A socket set is very helpful.
* Penetrating oil (like PB Blaster): Apply this to the caliper bolts beforehand to help prevent them from seizing.
* Wrench or socket to hold the caliper piston: To compress the caliper piston (see below). A caliper compression tool is ideal, but a large C-clamp can work in a pinch.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels opposite the one you're working on. Jack up the vehicle and securely support it on jack stands.
2. Remove the Wheel: Use your lug wrench to remove the lug nuts. Keep the nuts together in a safe place. Remove the wheel.
3. Remove the Caliper:
* Locate the caliper bolts: These are usually on the back of the caliper.
* Apply penetrating oil: Spray penetrating oil onto the bolts and let it sit for a few minutes.
* Remove the caliper bolts: Use the appropriate wrench or socket to carefully remove the caliper bolts.
* Support the caliper: The caliper is heavy and contains brake fluid. Use a bungee cord, wire, or even hang it from something nearby to keep it from dangling and stressing the brake line. Do not let the brake line hang freely.
4. Compress the Caliper Piston: The caliper piston needs to be compressed to allow the rotor to clear it. Use a caliper compression tool (best option) or carefully compress the piston using a C-clamp and a suitable sized piece of wood or metal to distribute pressure evenly on the piston itself. Do this slowly and avoid damaging the piston seal.
5. Remove the Rotor:
* Inspect the rotor: Look for any retaining clips or screws. Some rotors may have a single screw that needs to be removed.
* Try to remove the rotor by hand: Sometimes you can simply pull it off.
* Use a C-clamp or rotor puller: If the rotor is stuck, carefully use a C-clamp or rotor puller to pull it off the hub. Place the clamp's jaws on the rotor's studs and apply pressure. Be careful not to damage the wheel hub or rotor. A hammer might be needed to gently tap around the rotor to break it free, but avoid excessive force.
6. Clean and Inspect: Clean the hub mating surface before installing the new rotor. Inspect the wheel hub for any damage.
7. Installation: Installation is the reverse of removal. Remember to lubricate the rotor's mounting surface slightly with high-temperature grease to ensure smooth rotation.
Important Considerations:
* Brake Pads: Inspect your brake pads while you have the caliper off. Replace them if they're worn.
* Brake Fluid: If you're working on the brakes, be mindful of the brake fluid. Avoid getting it on your skin or paint.
* Professional Help: If you're unsure about any step, it's always best to seek professional help from a qualified mechanic. Brake work is critical for safety.
This is a general guide. Consult a repair manual specific to your 1989 Chevy S-10 for detailed instructions and diagrams. Your particular model might have slight variations.
