how to fix a sticking brake caliper on Volkswagen Golf MK5 (2004-2008)?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface, and engage the parking brake.
• Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

• Use a lug wrench to loosen the lug nuts, then lift the vehicle with a jack.
• Secure it on jack stands for safety.
• Remove the lug nuts and take off the wheel to expose the brake assembly.

3. Remove Caliper

• Locate the caliper mounting bolts using a socket set.
• Use the appropriate socket to remove the caliper mounting bolts.
• Carefully slide the caliper off the brake rotor, ensuring not to damage the brake line. Suspend the caliper using a bungee cord or rope to avoid stress on the brake line.

4. Inspect and Clean

• Check the caliper slides (pins) for rust or debris. Clean with brake cleaner and a wire brush.
• If the caliper is sticking, inspect the piston for dirt buildup. Clean the piston using a soft cloth.
• Apply brake grease on the caliper slides and reinsert them ensuring they move freely.

5. Reassemble

• Reattach the caliper onto the brake rotor and secure it with the mounting bolts. Torque the bolts to the manufacturer's specifications (typically around 25-30 Nm).
• Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even pressure.

6. Final Checks

• Reconnect the battery and pump the brake pedal to ensure proper feel.
• Inspect brake fluid level and top off if necessary.
