This is a general guide; specifics may vary slightly depending on your exact Montana trim. Always consult your owner's manual for model-specific information and torque specifications.
Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the vehicle.
* Lug wrench: To remove the wheels.
* Sockets and wrenches: You'll need a variety of sizes, likely including those for caliper bolts, and possibly a wrench for the caliper piston.
* C-clamp or brake caliper piston compressor tool: To compress the caliper piston to make room for the new, thicker pads.
* Penetrating oil (PB Blaster, etc.): To help loosen rusted bolts.
* Wrench or socket for caliper bracket bolts (if needed): Sometimes the entire caliper bracket needs to be removed.
* New brake pads: Make sure you get the correct pads for your 2000 Pontiac Montana.
* Gloves: To keep your hands clean.
* Safety glasses: To protect your eyes.
* Torque wrench: Crucial for tightening bolts to the correct specification.
Procedure (General Steps):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Wear safety glasses and gloves.
2. Raise and Secure the Vehicle: Use the jack to lift the vehicle and securely place it on jack stands. Never work under a vehicle supported only by a jack.
3. Remove the Wheel: Remove the lug nuts and take off the wheel.
4. Expose the Brake Caliper: You should now see the brake caliper clamping onto the rotor.
5. Compress the Caliper Piston: Using the C-clamp or piston compressor tool, carefully compress the brake caliper piston. This makes room for the new, thicker brake pads. Be careful not to damage the piston or boot. Some pistons turn as you compress them; you may need to rotate them as you compress.
6. Remove the Brake Pads: There are usually retaining clips or pins holding the brake pads in place. Remove these carefully. The old pads should now slide out.
7. Clean the Caliper and Mounting Bracket: Clean any dirt or debris from the caliper and the mounting bracket.
8. Install the New Brake Pads: Insert the new brake pads into the caliper. Make sure they are seated correctly. Replace any retaining clips or pins.
9. Reinstall the Wheel: Carefully reinstall the wheel and tighten the lug nuts to the manufacturer's specified torque. Don't overtighten!
10. Lower the Vehicle: Slowly lower the vehicle using the jack.
11. Pump the Brakes: Get back in the car and pump the brake pedal several times to engage the new pads.
12. Test Drive: Take a short test drive to ensure the brakes are functioning correctly. Listen for any unusual noises.
Important Considerations:
* Rotor Condition: Inspect the brake rotors for wear and tear. If they are excessively worn, scored, or warped, they will need to be replaced or resurfaced.
* Caliper Condition: Inspect the brake calipers for leaks, sticking pistons, or other damage. If there's a problem, the caliper may need to be replaced or rebuilt.
* Brake Fluid: If you're doing a lot of brake work, consider bleeding the brakes to remove any air bubbles that may have entered the system.
This is a simplified guide. It is strongly recommended that you find a repair manual specific to your 2000 Pontiac Montana. YouTube videos demonstrating the process for similar vehicles can also be helpful, but always prioritize safety and accuracy. If you are unsure about any step, seek professional assistance. Incorrect brake installation can be extremely dangerous.
