However, if you're determined to do it yourself, here's a general overview. This is not a comprehensive guide and should not be considered a substitute for a professional repair manual specific to your year and model of Pontiac Transport. You'll need that manual for precise torque specifications, part numbers, and diagrams.
Tools You'll Likely Need:
* Jack and jack stands: Absolutely essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheels.
* Brake caliper piston compressor tool: Essential for compressing the caliper piston to make room for new pads. A C-clamp *can* work, but a proper tool is safer and easier.
* Sockets and wrenches: Various sizes, likely including metric.
* Wrench for bleed screws: For bleeding the brakes after the job.
* Brake cleaner: To clean parts.
* New brake pads and rotors (possibly calipers): Get the correct parts for your year and model Transport.
* Torque wrench: To tighten bolts to the correct specification. This is crucial for safety.
* Gloves and safety glasses: Protect yourself.
* Optional: Wheel alignment tool (if you replace rotors)
General Steps (Vary by Year and Model):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Jack up the vehicle and securely support it on jack stands.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Inspect the Brake System: Carefully examine the brake pads, rotors, and calipers for wear, damage, or corrosion. Replace any parts that are worn or damaged beyond safe limits.
4. Remove the Caliper: This usually involves removing a couple of bolts securing the caliper to the bracket. Carefully support the caliper with a wire or bungee cord to prevent it from hanging by the brake line.
5. Compress the Caliper Piston: Use the piston compressor tool to push the piston back into the caliper. This creates space for the new, thicker brake pads. Be careful not to damage the piston seal.
6. Remove the Old Brake Pads: These usually just slide out.
7. Install New Brake Pads: Slide the new pads into place.
8. Install New Rotors (if needed): If the rotors are worn or scored, replace them. These usually bolt onto the wheel hub.
9. Reinstall the Caliper: Bolt the caliper back onto the bracket.
10. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts to the correct torque specification. Do not overtighten.
11. Bleed the Brakes (Important!): After replacing any part of the braking system, you MUST bleed the brakes to remove any air that may have entered the system. This is usually done by opening the bleed screws on each caliper one at a time while someone pumps the brake pedal. There are many videos online demonstrating this process. If you're unsure about this step, take your car to a mechanic.
12. Lower the Vehicle: Carefully lower the vehicle to the ground.
13. Test the Brakes: Before driving, test the brakes gently several times to ensure they are working properly. If anything feels off, stop immediately and have a mechanic check your work.
Again, this is a very simplified overview. Consult a repair manual specific to your year and model Pontiac Transport for detailed instructions, torque specifications, and diagrams. Improperly installed brakes can lead to serious injury or death. If you have any doubts, hire a qualified mechanic.
