Tools You'll Need:
* Jack and jack stands
* Lug wrench
* Wheel chocks
* Socket wrench set (metric) – likely you'll need 12mm, 14mm, and possibly others depending on your caliper.
* C-clamp or brake caliper compression tool
* Pliers
* Wire brush (optional, for cleaning caliper surfaces)
* Brake cleaner
* New front brake pads (ensure they are the correct fit for your 626)
* Gloves
Steps:
1. Safety First: Park on a level surface, engage the parking brake firmly, and chock the rear wheels. Raise the front of the car using the jack and securely place it on jack stands.
2. Remove the Wheel: Use the lug wrench to loosen the lug nuts on the wheel you're working on. Once loosened, jack the car up high enough to remove the wheel completely. Set the wheel aside in a safe place.
3. Locate the Caliper: The brake caliper is the metal housing that holds the brake pads. You'll see it clearly on the rotor (the spinning metal disc).
4. Compress the Caliper Piston: This is crucial. The piston needs to be pushed back into the caliper to make room for the new, thicker brake pads. Use a C-clamp or a dedicated brake caliper compression tool to carefully compress the piston. Important: Make sure to push the piston in straight to avoid damaging the seals. The piston may have to be rotated as it compresses. If fluid comes out, it's normal, but it could also mean a bad seal. If it appears excessive, consult a mechanic.
5. Remove the Caliper: There are usually two bolts holding the caliper to the caliper bracket. Use your socket wrench to remove these bolts. Carefully support the caliper; it's heavy and filled with brake fluid. You may need to carefully hang it from the suspension with wire or a bungee cord to prevent it from dangling and straining the brake line.
6. Remove the Old Brake Pads: The old brake pads should now be easily accessible. They are usually held in place by a retaining pin or clip. Remove them carefully. Inspect the brake rotors for excessive wear or scoring. If necessary, you'll have to resurface or replace them.
7. Clean the Caliper and Bracket: Use a wire brush to remove any rust or debris from the caliper mounting bracket and caliper. Clean the surfaces with brake cleaner.
8. Install the New Brake Pads: Install the new brake pads, ensuring they are correctly seated in the caliper. If there are shims or clips, install them too.
9. Reinstall the Caliper: Carefully reattach the caliper to the bracket, using the bolts you removed earlier. Tighten them to the manufacturer's specifications (consult your repair manual).
10. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts in a star pattern.
11. Lower the Vehicle: Carefully lower the vehicle to the ground. Fully tighten the lug nuts.
12. Pump the Brakes: Before driving, pump the brake pedal several times to engage the new pads.
13. Test Drive: Test drive the car to verify that the brakes work correctly.
Important Notes:
* Repair Manual: A repair manual specific to your 1995 Mazda 626 is highly recommended. It will provide detailed diagrams, torque specifications, and other crucial information.
* Brake Fluid: If you needed to substantially compress the piston, it’s good practice to check your brake fluid level and top it off if necessary. You may also want to have it checked after driving it a few days.
* Rotor Resurfacing/Replacement: If your brake rotors are heavily scored or worn, they should be resurfaced or replaced. A mechanic usually does this properly.
This guide provides general instructions. Variations may exist depending on your specific model and year. Always consult a repair manual for your car for precise details and safety precautions. If you are unsure about any step, seek professional help. Improper brake repair can be dangerous.
