Brake pad replacement is a crucial component of routine vehicle maintenance that ensures safety and optimal performance. While it might seem like a job for a professional mechanic, with the right tools and a bit of patience, you can undertake this task yourself. This article guides you through the process of installing new brake pads on your vehicle.
Safety should be your primary concern when performing any work on your vehicle. If you are not confident in your abilities or lack the proper tools, it is recommended that you seek professional assistance.
Preparation
Tools & Materials Needed:
- New brake pads
- A car jack and jack stands
- Lug wrench
- C-clamp or brake calliper tool
- Ratchet and socket set
- Wire brush
- Brake parts cleaner
- High-temperature automotive grease
- Safety glasses and gloves
- Ensure that you have the correct brake pads for your vehicle model
Park your vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Loosen the lug nuts on the wheel covering the brakes you intend to service before lifting the vehicle.
Steps to Install Brake Pads
Step 1: Remove the Wheel
Jack up the vehicle and secure it on the jack stands. Fully remove the loosened lug nuts to take the wheel off, exposing the brake components.
Step 2: Remove the Brake Caliper
Locate the calliper bolts and remove them using the ratchet and socket set. Lift the calliper away from the brake rotor gently. Hang it from the suspension using a piece of wire or a bungee cord to prevent stress on the brake hose.
Step 3: Remove Old Brake Pads
Slide out the old brake pads from the calliper bracket. Some vehicles have clips or retaining rings that need to be undone; consult your vehicle’s manual if necessary.
Step 4: Compress the Caliper Piston
Before installing new brake pads, the calliper piston must be pushed back into the calliper. Use a C-clamp or a specialised calliper tool to carefully compress the piston, ensuring even pressure to prevent any damage.
Step 5: Clean and Inspect
Use a wire brush to remove any rust or debris from the calliper bracket where the pads slide. Inspect the brake rotor for signs of wear or damage. Spray the area with brake part cleaner to eliminate dust and grime.
Step 6: Apply Grease
Lightly apply high-temperature grease to the parts of the brake pad that make contact with the calliper bracket to ensure smooth operation and prevent squealing.
Step 7: Install New Brake Pads
Insert the new brake pads into the calliper bracket. Ensure they are seated properly and any clips or retainers are secured.
The Corsa C lowering springs process is not difficult, so anyone with garage access and a little know-how can accomplish this modification. Since lowering springs are designed to work with your existing factory suspension, they can simply replace your coil springs
Step 8: Reattach the Brake Caliper
Once the new pads are in place, reposition the calliper over the rotor and pads. Apply grease to the calliper bolts and re-install them. Torque the bolts to your vehicle’s manufacturer’s specifications.
Step 9: Reinstall the Wheel
Put the wheel back on and hand-tighten the lug nuts. Lower the vehicle off the jack stands and then fully tighten the lug nuts in a star pattern.
Step 10: Test
Before driving, start the engine and gently press the brake pedal a few times to allow the calliper piston to adjust to the new pads. This will avoid a soft brake pedal when you first take to the road.
Step 11: Bed-In the New Pads
Follow the bed-in procedure as recommended by the brake pad manufacturer. This usually involves making a series of stops at different speeds to properly seat the brake pads and ensure optimum performance and longevity.
Conclusion
Installing brake pads can be an extremely rewarding DIY project. Always refer to your vehicle’s service manual for specific instructions and torque specifications related to your car. Remember to check your work thoroughly and take a safe test drive in a low-traffic area to make sure everything is functioning correctly.
