Tools You'll Need:
* Jack and jack stands: Securely support the vehicle. Never work under a car supported only by a jack.
* Lug wrench: To remove the wheels.
* Wheel chocks: To prevent the car from rolling.
* Socket wrench and sockets: Appropriate sizes for lug nuts and caliper mounting bolts.
* C-clamp or caliper compression tool: To compress the caliper piston.
* Wrench or socket for caliper mounting bolts: Size varies depending on the caliper.
* Torque wrench: To tighten bolts to the manufacturer's specifications.
* Penetrating lubricant (PB Blaster or similar): To loosen rusted bolts.
* Brake cleaner: To clean the mating surfaces.
* New brake rotors: Make sure you get the correct ones for your 1988 Dodge Colt.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
Steps:
1. Safety First: Engage the parking brake, chock the wheels, and ensure the vehicle is on a level surface.
2. Remove the Wheel: Loosen the lug nuts slightly before jacking up the car. Jack up the car and securely place it on jack stands. Completely remove the lug nuts and take off the wheel.
3. Remove the Caliper:
* Locate the caliper mounting bolts. These are usually on the back of the caliper.
* Compress the caliper piston: Using the C-clamp or compression tool, slowly compress the caliper piston to create enough space for the new rotor. Be careful not to damage the piston or seals. You might need to add brake fluid to the reservoir as you compress the piston.
* Remove the caliper mounting bolts. Apply penetrating lubricant if they are stuck. Carefully remove the caliper and hang it out of the way using a wire or bungee cord to prevent it from dangling and damaging the brake hose.
4. Remove the old rotor: Sometimes the old rotor will simply slide off. Other times, it might be stuck due to rust. If stuck, gently tap it from the back with a hammer and punch, working your way around the rotor. Be careful not to damage the wheel hub.
5. Clean the Hub: Thoroughly clean the wheel hub mating surface with brake cleaner to remove any rust, debris, or old brake material.
6. Install the new rotor: Carefully slide the new rotor onto the wheel studs. Ensure it sits flush against the hub.
7. Reinstall the Caliper: Mount the caliper back onto its mounting bracket. Tighten the caliper mounting bolts to the manufacturer's specified torque.
8. Reinstall the wheel: Put the wheel back on, tighten the lug nuts in a star pattern (opposite nuts), and lower the car. Torque the lug nuts to the manufacturer's specification.
9. Check for proper brake function: Pump the brake pedal several times to build pressure, then test the brakes in a safe, open area. Check for any unusual noises or vibrations.
Important Considerations:
* Brake Pads: Inspect your brake pads while you're at it. If they're worn, replace them at the same time. Replacing rotors without replacing worn pads isn't recommended.
* Wheel Bearings: Inspect your wheel bearings for play or noise.
* Torque Specifications: Refer to your owner's manual or a repair manual for the correct torque specifications for lug nuts and caliper bolts. Using the wrong torque can damage components.
* Brake Fluid: Check your brake fluid level before and after the procedure. Top it off if necessary. Brake fluid absorbs moisture over time and should be flushed regularly.
This is a general guide. The exact procedure may vary slightly depending on your specific 1988 Dodge Colt model. Always consult a repair manual specific to your vehicle for detailed instructions and torque specifications. If in doubt, seek professional help. Brake failure is dangerous.
