Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the brakes to cool before touching any components after driving.

Symptoms

•Noticeable resistance when driving, especially when the brake pedal is released
•Increased heat from the wheel area
•Reduced fuel efficiency
•Unusual noise when brakes are applied (squeaking or grinding)
•Brake warning light illuminated on the dashboard

Diagnostic Steps

1
Inspect brake pedal operation for binding or sticking.
2
Check for any visible damage or corrosion on brake calipers.
3
Inspect brake lines for kinks or leaks.
4
Measure rotor temperature using an infrared thermometer to identify hotspots.
5
Remove the wheel and check for proper clearance between the caliper and rotor.
6
Assess brake pads for uneven wear or contamination.

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

Diagnostic Steps

1
Inspect brake pedal operation for binding or sticking.
2
Check for any visible damage or corrosion on brake calipers.
3
Inspect brake lines for kinks or leaks.
4
Measure rotor temperature using an infrared thermometer to identify hotspots.
5

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake fluid, multimeter.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Wheel Removal

Use the lug wrench to loosen the wheel nuts.
Lift the vehicle using the jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Brake Caliper Inspection

Check the caliper for proper operation. If it appears stuck, proceed to remove it.
Sub-steps:
1. Remove the caliper bolts using the appropriate socket.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang from the brake line).
3. Inspect the caliper slides and ensure they move freely. Lubricate them with brake grease if necessary.

4. Brake Pad and Rotor Assessment

Inspect the brake pads for wear; replace if the friction material is below 3mm.
Check the rotors for warping or excessive scoring.
Sub-steps:
1. If the pads are worn, remove them by unhooking the retaining clips.
2. Measure the rotor thickness; replace if below manufacturer specifications (usually around 24mm for XC90).
3. Clean the rotor surface with brake cleaner to remove dust and debris.

5. Brake Line and Fluid Check

Inspect brake lines for any signs of wear or damage.
Check brake fluid level and condition; replace if contaminated or low.
Sub-steps:
1. If brake lines are damaged, replace them following the manufacturer’s guidelines.
2. Bleed the brakes to remove any air that may cause dragging.

6. Reassembly

Reinstall the brake caliper and ensure that all bolts are tightened to the manufacturer's torque specifications (typically around 25-35 ft-lbs).
Reattach the wheel and tighten the lug nuts in a star pattern to ensure even pressure.
