Problem Statement

Learn how to diagnose and fix shaking during braking in Volkswagen Golf MK7 (2015-2019). Step-by-step guide with symptoms, diagnostic steps, and repair instructions.

Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery when working on electrical components.
•Allow sufficient time for brake components to cool before handling.

Symptoms

•Steering wheel shakes during braking
•Vehicle vibrates noticeably when applying brakes
•Brake pedal pulsates or feels uneven
•Increased stopping distance
•Possible noise from the braking system (squeaking or grinding)

Diagnostic Steps

1
Inspect brake components for wear: check brake pads, rotors, and calipers visually for damage or abnormal wear.
2
Use an OBD-II scanner to check for any stored error codes related to the braking system or traction control.
3
Perform a wheel alignment check to determine if misalignment is contributing to the shaking.
4
Check tire condition and pressure: look for uneven wear and ensure proper inflation.
5
Test the rotors for warpage using a dial indicator gauge to measure runout.
6
Inspect suspension components (control arms, bushings, and tie rods) for wear or looseness.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•OBD-II scanner
•Jack and jack stands
•Socket set
•Torque wrench
•Dial indicator gauge (for rotor runout measurement)

Parts Required

•Brake pads
•Brake rotors (if warped or damaged)

Solution

1. Preparation

Gather tools and parts: ensure you have all necessary tools and replacement parts before starting.
Safety first: park the vehicle on a level surface, engage the parking brake, and wear safety glasses.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the braking system.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove caliper bolts using a socket set (usually 13mm or 15mm).
- Slide the caliper off the rotor and support it (do not let it hang from the brake line).
- Remove the old brake pads and replace them with new ones, ensuring they are oriented correctly.
Brake Rotors:
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- If replacing, install the new rotor and torque screws to the manufacturer’s specifications (typically around 10 Nm).

4. Check and Adjust Other Components

Wheel Alignment:
- After brake replacement, take the vehicle to a professional alignment shop to ensure proper wheel alignment.
Suspension Inspection:
- If any suspension components are damaged or worn, replace them with OEM or high-quality aftermarket parts.

5. Reassemble

Reattach the caliper, ensuring all bolts are torqued to manufacturer specifications (typically around 30 Nm).
Reinstall the wheel and hand-tighten lug nuts before lowering the vehicle.
Lower the vehicle and torque lug nuts to the manufacturer’s specification (usually around 120 Nm).
