why does my Volvo XC90 shake when I brake at high speeds

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Raise the vehicle using a jack and secure it with jack stands.

2. Remove Wheels

• Using a socket set, loosen the lug nuts on the front wheels before raising the vehicle.
• Remove the wheels to access the brake components.

3. Inspect Brake Components

• Brake Pads: Check for uneven wear; replace if thickness is below 3mm.
• Brake Rotors: Measure thickness and check for warping. Replace if warping exceeds manufacturer's specifications (typically 0.002 inches or more).
• Calipers: Inspect calipers for proper function and fluid leaks.

4. Replace Brake Rotors (if necessary)

• Remove the caliper bracket bolts and carefully remove the caliper.
• Slide off the old rotor; if it's stuck, gently tap it with a rubber mallet.
• Install the new rotor and reattach the caliper.

5. Replace Brake Pads (if necessary)

• Compress the caliper piston using a caliper tool to allow new pads to fit.
• Install new brake pads in the caliper bracket.
• Reassemble the caliper over the pads and secure it with bolts to manufacturer torque specifications (typically 20-30 Nm).

6. Reassemble and Test

• Reinstall the wheels and tighten lug nuts to the manufacturer's torque specifications (typically 100-120 Nm).
• Lower the vehicle and check brake fluid level; top off if necessary.
• Test drive the vehicle to ensure the issue is resolved.
