why does my Volvo XC60 536 (2017-Present) steering wheel shake when I brake

Solution

1. Preparation

• Gather tools and parts. Ensure the vehicle is parked on a level surface.
• Required tools: jack, jack stands, lug wrench, torque wrench, dial indicator, OBD-II scanner.
• Safety warning: Always wear safety gear and ensure the vehicle is secure on jack stands.

2. Remove Wheel

• Loosen lug nuts slightly while the vehicle is on the ground.
• Lift the vehicle using a jack and secure it with jack stands.
• Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

• Inspection: Use a dial indicator to measure rotor runout. If it exceeds manufacturer specifications (typically 0.002-0.004 inches), replace the rotors.
• Replacement:
  • Remove caliper by unscrewing the caliper bolts (torque specification: typically 25-35 Nm).
  • Hang the caliper using a bungee cord to avoid strain on the brake line.
  • Remove the rotor (if stuck, use a rubber mallet to tap it free).
  • Install new rotor, ensuring it is properly seated.
  • Reinstall caliper and torque bolts to specifications.

4. Inspect and Replace Brake Pads

• Check brake pads for thickness; replace if below 3mm.
• If unevenly worn, inspect caliper slides for proper movement.
• Replace pads as necessary:
  • Remove old pads from the caliper bracket.
  • Compress caliper piston using a C-clamp before installing new pads.
  • Install new pads and ensure they are seated correctly.

5. Check Suspension Components

• Visually inspect control arms, tie rods, and bushings for signs of wear or damage.
• Replace any worn components as necessary, following manufacturer specifications for torque settings.

6. Wheel Alignment and Balancing

• After reassembling, check wheel alignment using an alignment tool.
• If misaligned, adjust to specifications.
• Balance the tires if necessary to eliminate vibrations.
