Tools You'll Likely Need:
* Jack and jack stands (essential for safety!)
* Lug wrench
* Wheel chocks
* Socket wrench set (metric)
* Wrenches (metric)
* Brake caliper piston compressor tool
* C-clamp (can sometimes be used instead of a caliper piston compressor)
* Wire brush
* Brake cleaner
* New brake pads
* New brake rotors (if needed; inspect them carefully)
* Anti-seize lubricant
* Penetrating oil (like PB Blaster)
* Gloves
* Safety glasses
General Steps (for drum or disc brakes; you need to determine which type your Colorado has):
I. Rear Disc Brakes (More Common on Newer Models):
1. Safety First: Park on a level surface, engage the parking brake, chock the front wheels, and jack up the rear of the vehicle securely using jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper: There are usually bolts holding the caliper to the caliper bracket. Use the appropriate wrench to remove these bolts. Carefully support the caliper with a bungee cord or wire to keep it from hanging by the brake line.
4. Compress the Caliper Piston: Using the caliper piston compressor tool, slowly compress the piston back into the caliper. This creates space for the new, thicker brake pads. *Be careful not to damage the piston or the caliper.*
5. Remove the Old Brake Pads: Remove the old brake pads. You may need to remove a retaining pin or clip depending on the design.
6. Inspect the Rotors: Examine the brake rotors for wear, scoring, or excessive rust. If they are worn beyond the minimum thickness specified in your owner's manual, they need to be replaced.
7. Install New Brake Pads: Install the new brake pads, ensuring they slide smoothly into their guides.
8. Reinstall the Caliper: Reinstall the caliper and bolts, tightening to the manufacturer's specified torque.
9. Reinstall the Wheel: Reinstall the wheel and tighten the lug nuts to the manufacturer's specified torque.
10. Lower the Vehicle: Carefully lower the vehicle to the ground.
11. Pump the Brakes: Pump the brake pedal several times to restore brake pressure.
II. Rear Drum Brakes (Less Common on Newer Models):
1. Safety First: (Same as above)
2. Remove the Wheel: (Same as above)
3. Remove the Drum: The drum is held in place by the wheel studs. Sometimes it may be stubborn due to rust; use a rubber mallet to gently tap it off.
4. Remove the Brake Shoes: Once the drum is off, you'll see the brake shoes. There are usually springs, clips, and possibly an adjuster mechanism holding them in place. Carefully disassemble these components. Take pictures or make notes to help with reassembly.
5. Inspect the Drums and Shoes: Inspect the drums for scoring or excessive wear. Inspect the brake shoes for wear and lining thickness. Replace as needed.
6. Install New Brake Shoes: Install the new brake shoes and carefully reassemble all the springs, clips, and adjuster mechanism. Refer to a repair manual or online video for specific instructions.
7. Reinstall the Drum: Carefully slide the drum back onto the wheel studs.
8. Reinstall the Wheel: (Same as above)
9. Lower the Vehicle: (Same as above)
10. Pump the Brakes: (Same as above)
Important Considerations:
* Repair Manual: Always consult your vehicle's repair manual for detailed instructions, torque specifications, and diagrams specific to your year and model.
* Safety: Working on brakes is critical. If you're not comfortable performing this repair, take your vehicle to a qualified mechanic.
* Bleeding Brakes: After replacing any brake components, it's a good idea to bleed the brakes to remove any air bubbles from the brake lines. This is best done by a professional.
This guide provides general steps. Improper brake repair can lead to accidents. If unsure, seek professional help.
