Tools you'll likely need:
* Jack and jack stands
* Wheel chocks
* Wrench set (metric)
* Socket set (metric)
* Torque wrench
* C-clamp or brake caliper compressor tool
* Penetrating oil (like PB Blaster)
* Wire brush
* Brake cleaner
* Gloves
* Rags
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the rear wheels. Raise the front of the vehicle using the jack and securely support it with jack stands. Remove the wheel.
2. Remove the Caliper:
* Locate the caliper bolts: These are usually on the back of the caliper, holding it to the caliper bracket. They may be 14mm or 15mm.
* Apply penetrating oil: Spray penetrating oil on the bolts to loosen them if they're stuck. Let it sit for a few minutes.
* Remove the bolts: Carefully unscrew the bolts using the appropriate wrench or socket.
* Remove the caliper: Carefully lift the caliper away from the rotor. It might still be attached by the brake line; be mindful of this. You may need to support the caliper's weight with a bungee cord or wire to prevent it from hanging by the brake line.
3. Compress the Caliper Piston:
* Use a C-clamp or caliper compressor: This tool is crucial. Carefully compress the piston back into the caliper. Important: You may need to twist the piston as you compress it to overcome any corrosion or sticking. Some pistons have bleeder valves; if you have one, open it slightly to facilitate compression. Be very gentle and don't damage the piston seal.
* Alternatively: Some people use a large screwdriver or similar tool, carefully wedged between the piston and the caliper body to compress it. This method is riskier and can damage the piston if done incorrectly; the C-clamp is the preferred method.
4. Remove the Brake Pads:
* Locate the pad retaining pins or clips: These hold the brake pads in place. They are usually pins or clips located on the outer edge of the brake pad.
* Remove the retaining pins/clips: Use the appropriate tool (often a small punch or screwdriver) to remove these.
* Remove the brake pads: Carefully slide the old brake pads out of the caliper.
5. Inspect Components:
* Inspect the brake pads: Check the pad thickness. Replace them if they're worn below the minimum thickness.
* Inspect the rotor: Check the rotor for wear, scoring, or cracks. If necessary, you may need to have the rotor resurfaced or replaced.
* Inspect the caliper: Look for damage or leaks.
* Inspect the caliper bracket: Examine for cracks or damage.
6. Reassembly:
* Install new brake pads: Carefully slide the new brake pads into the caliper.
* Install retaining pins/clips: Make sure they are secure.
* Reinstall the caliper: Mount the caliper back onto the caliper bracket, ensuring the caliper slides freely.
* Tighten caliper bolts: Tighten the caliper bolts to the manufacturer's specified torque. (Consult your vehicle's repair manual).
* Lower the vehicle: Carefully lower the vehicle from the jack stands.
7. Bleed the Brakes: After reassembly, you'll need to bleed the brakes to remove any air that may have entered the brake lines. This is crucial for proper braking performance. Refer to your vehicle's repair manual for bleeding instructions. This usually involves using a brake bleeder tool at each caliper.
Important Notes:
* Consult a Repair Manual: A repair manual specific to your 2001 Oldsmobile Aurora is highly recommended. It will provide detailed diagrams, torque specifications, and other important information.
* Parts: Obtain replacement brake pads of the correct size and type. You may also need rotors and other components depending on your inspection.
* Safety: Brakes are critical safety components. If you're unsure about any part of this process, seek professional help.
This detailed explanation provides a general overview. The specifics might vary slightly depending on your vehicle's exact configuration. Always refer to your vehicle's repair manual for the most accurate instructions.
