my Volkswagen Golf MK5 (2004-2008) rear brakes are grinding, what should I check?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and engage the parking brake.
• Loosen the lug nuts on the rear wheels before lifting the vehicle.

2. Lift the Vehicle

• Use a floor jack to lift the rear of the vehicle and secure it with jack stands.
• Remove the rear wheels to access the brake components.

3. Remove Brake Calipers

• Use a socket set to remove the caliper mounting bolts.
• Carefully slide the caliper off the brake rotor and support it with a bungee cord to avoid straining the brake line.

4. Inspect and Replace Brake Pads

• Remove the old brake pads from the caliper bracket.
• Check the condition of the caliper bracket and clean any debris.
• Install new brake pads, ensuring they are properly aligned with the caliper.

5. Inspect and Replace Brake Rotors (if necessary)

• Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.
• If the rotor is damaged, replace it with a new one.
• Clean the hub surface and install the new rotor, ensuring it is properly seated.

6. Reassemble Brakes

• Reattach the brake caliper over the new pads and rotor.
• Tighten the caliper mounting bolts to the manufacturer’s specified torque (usually around 25-30 Nm).
• Reinstall the rear wheels and hand-tighten the lug nuts.

7. Lower the Vehicle

• Carefully lower the vehicle back to the ground.
• Torque the lug nuts to the manufacturer’s specified value (typically 100-120 Nm).

8. Test Brake Function

• Pump the brake pedal a few times to seat the pads.
• Check for any unusual noises or issues during a test drive.
