🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen and lift the front

• Use the 19mm lug socket and breaker bar to loosen the front wheel bolts 1/4 turn.
• Lift the front of the XC90 with the floor jack and support it with jack stands.
• Remove the front wheel bolts and wheel.

Step 2: Remove the caliper

• Use the Torx T40 screwdriver to remove the caliper guide pin bolts.
• Lift the caliper off the bracket carefully.
• Hang the caliper with a bungee cord or mechanic’s hook.
• Never let the hose carry the weight.

Step 3: Remove the old pads and sensor

• Slide the old brake pads out of the caliper bracket.
• If equipped, disconnect the pad wear sensor from the pad and harness.
• Note the position of any pad clips before removing them.

Step 4: Clean and inspect

• Use the wire brush and brake cleaner to clean the caliper bracket and pad contact points.
• Check the rotor for heavy grooves, cracks, or blue heat spots.
• If the slider pins are dry or sticky, clean and lubricate them with brake grease.

Step 5: Compress the caliper piston

• Use the brake caliper compression tool (specialty) to push the piston fully back into the caliper.
• Watch the brake fluid reservoir while compressing the piston so it does not overflow.
• Compress slowly and evenly.

Step 6: Install the new pads

• Install the new pad clips into the bracket if included with the pad set.
• Apply a thin layer of brake grease to the pad ears and contact points.
• Install the new pads in the same positions as the old ones.
• Connect the new brake pad wear sensor if your XC90 is equipped with one.

Step 7: Reinstall the caliper

• Slide the caliper back over the new pads.
• Install the guide pin bolts with the Torx T40 screwdriver.
• Torque to 35 Nm (26 ft-lbs).

Step 8: Reinstall the wheel

• Put the wheel back on and hand-start the lug bolts.
• Lower the vehicle enough for the tire to touch the ground.
• Use the 19mm lug socket and torque wrench to tighten the lug bolts in a star pattern.
• Torque to 140 Nm (103 ft-lbs).

Step 9: Repeat on the other side

• Repeat the same procedure on the opposite front wheel.
• Always replace front pads in pairs.
