Tools You'll Need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Socket wrench set: Metric, likely including 13mm, 14mm, and potentially others.
* C-clamp or caliper compression tool: To push the caliper piston back in. A C-clamp is cheaper but a purpose-built tool is safer and easier.
* Wrench or socket to fit caliper bolt(s): This varies by model, so check your vehicle.
* Pliers: For removing cotter pins (if equipped).
* Brake cleaner: To clean the caliper and rotor.
* New brake pads: Make sure you get the correct pads for your specific 1999 Chevy Tracker model (2WD or 4WD, engine size will impact which pads are needed).
* Penetrating lubricant (like PB Blaster): Can help loosen stubborn bolts.
* Gloves: To protect your hands.
* Safety glasses: Protect your eyes from flying debris.
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels opposite the one you're working on. Use jack stands to securely lift the vehicle after using the jack to raise it.
2. Remove the Wheel: Use your lug wrench to remove the lug nuts and carefully take off the wheel.
3. Expose the Brake Caliper: You should now see the brake caliper clamping onto the rotor.
4. Remove the Caliper:
* Locate the caliper mounting bolts: These are usually on the back of the caliper.
* Apply penetrating lubricant if the bolts are difficult to remove.
* Unscrew the bolts and carefully remove the caliper. It's often helpful to support the caliper with a bungee cord or wire to prevent it from hanging by the brake line.
5. Compress the Caliper Piston: The piston needs to be pushed back into the caliper to make room for the new, thicker pads. Use a C-clamp or caliper compression tool. Do this slowly and steadily to avoid damaging the piston or seals. Be prepared for some brake fluid to be expelled. Have rags handy to catch any fluid.
6. Remove Old Brake Pads: The old brake pads should now be easily removable. Take note of their orientation for proper installation of the new pads.
7. Clean the Caliper and Rotor: Use brake cleaner to thoroughly clean the caliper, rotor, and any surrounding surfaces.
8. Install New Brake Pads: Carefully install the new brake pads, ensuring they slide freely and are properly seated in their grooves.
9. Reinstall the Caliper: Carefully reattach the caliper to the mounting brackets and tighten the bolts to the manufacturer's specified torque.
10. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts snugly.
11. Lower the Vehicle: Carefully lower the vehicle using the jack. Once it's on the ground, fully tighten the lug nuts in a star pattern.
12. Final Check: Pump the brake pedal several times to ensure the pads are making proper contact with the rotor. Test drive the vehicle cautiously and check for any unusual noises or brake performance issues.
Important Considerations:
* Brake Fluid: If you have to significantly compress the caliper piston, you may need to check and top off your brake fluid reservoir. Low brake fluid is a serious problem.
* Rotor Condition: Inspect the rotor for excessive wear or damage. If it's grooved or warped, it may need to be resurfaced or replaced.
* Caliper Condition: Inspect the caliper for leaks or damage. A sticking caliper can cause uneven brake pad wear.
* Bleeding Brakes: In some cases, air might enter the brake lines during this process requiring brake bleeding to restore proper functionality. Consult your owner's manual for proper bleeding instructions.
This is a general guide. There can be variations depending on the specific year and model of your 1999 Chevy Tracker. If you are uncomfortable performing this repair, it's best to take your vehicle to a qualified mechanic. Improperly installed brakes can be extremely dangerous.
