🔧 Yukon - Front Brake Pads & Rotor Replacement

You’ll remove the front wheels, take off the calipers and brackets, replace the rotors, then install new pads and reassemble with the correct torque. Doing both sides together keeps braking even and safe.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

Assumption: your Yukon has the common front caliper hardware (13mm slide bolts, 21mm bracket bolts); verify bolt head sizes before starting.

⚠️ Safety & Precautions

• ⚠️ Work on level ground and chock the rear wheels before lifting.
• ⚠️ Support the SUV with jack stands; never rely on the floor jack.
• ⚠️ Do not let the caliper hang by the brake hose; it can damage the hose.
• ⚠️ Brake dust is harmful; use brake cleaner, not compressed air.
• ⚠️ Watch brake fluid level; pushing pistons back can overflow the reservoir.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Chock both rear wheels using wheel chocks.
• Loosen the front lug nuts 1/2 turn with a 21mm socket and breaker bar before lifting.
• Open the hood and check the brake fluid level; remove a little fluid if it’s near “MAX.”
• “Brake hardware” = the stainless clips pads slide on.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and remove the front wheels

• Lift the front end using a floor jack (rated 3-ton minimum) at the front jacking point.
• Set the frame securely onto jack stands (rated 3-ton minimum).
• Remove lug nuts with a 21mm socket and take both front wheels off.

Step 2: Remove the front caliper (do not stretch the hose)

• Turn the steering wheel to give yourself room (left for right side work, right for left side work).
• Remove the caliper slide bolts using a 13mm socket and 3/8" drive ratchet.
• Lift the caliper off the bracket and hang it from the suspension using a caliper hanger hook.
• Hanger hook prevents hose damage.

Step 3: Remove old pads and inspect

• Pull the old pads out of the bracket by hand; use a flat blade screwdriver if they’re stuck.
• Check the caliper slide pins (the smooth pins the caliper floats on) for smooth movement.
• Clean dust with brake cleaner and shop towels.

Step 4: Remove the caliper bracket

• Remove the two large bracket bolts using a 21mm socket and 1/2" drive breaker bar.
• Set the bracket aside.
• During reassembly, bracket bolts: Torque to 300 Nm (221 ft-lbs).

Step 5: Remove the rotor

• Pull the rotor straight off the hub.
• If stuck from rust, spray the hub/rotor center with brake cleaner, then tap the rotor hat with a dead blow hammer to break it free.
• Clean the hub face with a wire brush so the new rotor sits flat.
• Flat hub = no brake pedal shake.

Step 6: Install the new rotor

• Clean both rotor friction surfaces using brake cleaner and shop towels (removes shipping oil).
• Place the new rotor onto the hub.
• Hold it in place by threading on one lug nut by hand (optional) and snug it with a 21mm socket.

Step 7: Reinstall the caliper bracket and new hardware clips

• Install the new stainless hardware/abutment clips onto the bracket (they snap in by hand).
• Reinstall the bracket bolts using a 21mm socket and 1/2" drive ratchet.
• Apply medium-strength threadlocker to clean bracket bolt threads if they are not pre-coated.
• Torque to 300 Nm (221 ft-lbs).

Step 8: Compress the caliper piston

• Place one old brake pad against the caliper piston face.
• Use a C-clamp (6" minimum) to slowly press the piston fully back into the caliper.
• Check the master cylinder fluid level under the hood while compressing and wipe any spills immediately.
• Go slow to avoid fluid overflow.

Step 9: Install new pads and lubricate the correct spots

• Apply a thin film of high-temperature silicone brake grease to pad ears where they contact the hardware clips (do not get grease on rotor or pad friction material).
• Install the inner and outer pads into the bracket by hand.

Step 10: Reinstall the caliper

• Lower the caliper over the new pads.
• Install and tighten the slide bolts using a 13mm socket and 3/8" drive torque wrench.
• Caliper slide bolts: Torque to 100 Nm (74 ft-lbs).

Step 11: Repeat on the other front side

• Repeat Steps 2 through 10 for the other front wheel.
• Do both sides to keep braking balanced.

Step 12: Reinstall wheels and torque lug nuts

• Reinstall both wheels and hand-thread all lug nuts.
• Lower the SUV until the tires touch the ground enough to stop spinning.
• Tighten lug nuts in a star pattern using a 21mm socket and 1/2" drive torque wrench.
• Wheel lug nuts: Torque to 190 Nm (140 ft-lbs).

✅ After Repair

• Pump the brake pedal 10-15 times until it feels firm before moving the SUV.
• Check brake fluid level and top off with DOT 3 if needed.
• Start the engine and confirm the pedal stays firm with power assist.
• Do a careful test drive and listen for abnormal grinding or pulling.
• Pad bedding (break-in): make 8-10 moderate stops from ~40 mph down to ~10 mph, allowing a little driving between stops for cooling.
