Diagnostic Steps

1
Inspect brake pads for uneven wear and thickness.
2
Check brake rotors for warpage or damage using a runout gauge.
3
Examine brake calipers for proper function and alignment.
4
Inspect brake fluid for contamination or low levels.
5

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Remove Wheel

Use a jack to lift the vehicle and securely place it on jack stands.
Remove the lug nuts with a socket wrench.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor (do not disconnect the brake line).
Take out the old brake pads.
Inspect the new brake pads for proper fit and thickness.
Install the new brake pads into the caliper bracket.

4. Resurface or Replace Brake Rotors

If rotors are warped, either resurface them or replace them with new ones.
To resurface, mount the rotor on a brake lathe and follow manufacturer specifications.
If replacing, ensure new rotors are compatible with the Golf MK7.5.

5. Reassemble Brake Components

Reattach the caliper over the new pads.
Tighten caliper bolts to manufacturer's torque specifications (usually around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Steps

Lower the vehicle and tighten lug nuts to the recommended torque (typically 100-120 Nm).
Reconnect the battery.
Pump the brake pedal several times to ensure proper brake function.
