Safety First:
* Engage the parking brake firmly.
* Use jack stands. Never work under a vehicle supported only by a jack.
* Wear safety glasses.
* Use gloves. Brake dust is irritating.
Tools You'll Likely Need:
* Jack and jack stands
* Lug wrench
* Wheel chocks
* Socket wrench set (metric)
* Torque wrench
* Brake caliper piston compressor tool
* Hammer (possibly a rubber mallet)
* Penetrating oil (like PB Blaster)
Procedure:
1. Raise and Secure the Vehicle: Safely raise the rear of the Equinox using a jack and securely place it on jack stands. Use wheel chocks on the front wheels.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Brake Caliper:
* Compress the caliper piston: Use a caliper piston compressor tool to push the piston back into the caliper. This creates space to remove the caliper. If the piston is difficult to compress, penetrating oil may help.
* Disconnect the brake line: Locate the brake line attached to the caliper. You'll likely need a wrench to loosen the retaining clip (if present) and carefully disconnect the line, being mindful not to damage it. Some systems use a retaining clip, others might just use a compression fitting. Be prepared for some brake fluid to leak – have a rag ready.
* Remove the caliper mounting bolts: Locate and remove the bolts holding the caliper to the caliper bracket. Carefully set the caliper aside, ensuring the brake line is not strained. You might want to hang the caliper from something to keep it out of the way and prevent straining the brake line.
4. Remove the Brake Rotor:
* Inspect for retaining clips or screws: Some Equinox models may have retaining clips or screws holding the rotor to the hub. If present, remove these first.
* Tap the rotor off: Gently tap the rotor off the hub using a hammer (preferably a rubber mallet). Start with light taps and work your way around the circumference of the rotor. If the rotor is stuck, penetrating oil applied to the hub mounting surface might help. Avoid striking the wheel studs.
5. Installation (Reverse Order): Once the new rotor is in, carefully reverse the steps to install everything. Remember to torque all bolts to the manufacturer's specifications. Bleed the brake system after the job to remove any air that might have gotten in.
Important Considerations:
* Year and Model Variations: The exact procedure may differ slightly depending on the year and specific model of your Equinox. Always consult your owner's manual or a reputable repair manual for your specific vehicle.
* Rust and Corrosion: If your Equinox is older or has been exposed to harsh weather, you may encounter significant rust or corrosion, making the process more challenging. Penetrating oil can help, but you might need additional tools or techniques.
* Professional Help: If you are not comfortable performing this repair yourself, take your Equinox to a qualified mechanic. Brake systems are critical for safety, and improper repair can be dangerous.
Remember, this is general guidance. Always prioritize safety and refer to your vehicle's specific repair manual before attempting this repair.
