⚠️ Safety & Precautions

• ⚠️ Support your Ridgeline with jack stands. Never work beneath a vehicle supported only by a floor jack.
• ⚠️ Replace front pads and rotors on both sides to maintain even braking.
• ⚠️ Brake dust can be harmful. Do not use compressed air to clean brake components.
• ⚠️ Brake cleaner is flammable. Work outside or in a well-ventilated area away from sparks.
• ⚠️ Do not press the brake pedal while a caliper is removed.
• ⚠️ Hang each caliper securely. Never allow its weight to pull on the brake hose.
• 🔋 Battery disconnection is not required for this front-brake repair.

📋 Before You Begin

• 🅿️ Park your Ridgeline on level, solid ground. Select Park, apply the parking brake, and switch off the engine.
• 🔒 Place wheel chocks firmly behind both rear wheels.
• 🌡️ Allow the brakes to cool completely before touching them.
• 📱 No infotainment service mode or scan-tool command is required for the front brakes.
• 🧴 Open the brake-fluid reservoir under the hood and check its level. If it is near MAX, use a brake-fluid syringe to remove a small amount so it cannot overflow when the pistons are compressed.
• 🧼 Keep brake fluid away from paint. Wipe spills immediately and rinse with water.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the Front Wheel Nuts

• Use a 22mm deep socket and 1/2-inch breaker bar to loosen each front wheel nut approximately one-half turn.
• Do not remove the wheel nuts while your Ridgeline is still on the ground.

Step 2: Raise and Support the Front

• Use the 2-ton floor jack at the approved front-center lifting point on the front subframe.
• Place 2-ton jack stands beneath the reinforced front side support points.
• Lower your Ridgeline slowly onto the stands, then gently push the body to confirm it is stable.
• Keep the floor jack lightly touching the lift point.

Step 3: Remove Both Front Wheels

• Use the 22mm deep socket and 3/8-inch ratchet to remove the wheel nuts.
• Remove both front wheels and slide them beneath the sides of your Ridgeline as additional protection.

Step 4: Remove the Brake Caliper

• Turn the steering wheel to provide better access to the caliper bolts on the side being serviced.
• Use a 14mm socket and 3/8-inch ratchet to remove the upper and lower caliper guide-pin bolts.
• Lift the caliper away from the pads. Use the brake caliper hanger to suspend it from the suspension spring.
• A guide pin is the smooth sliding pin that lets the caliper move as the brakes are applied.
• Do not disconnect the brake hose.

Step 5: Remove the Old Brake Pads

• Pull the inner and outer pads from the caliper bracket by hand.
• Use a small flat-blade screwdriver to remove the stainless-steel pad clips from the bracket.
• Note the position of the pad wear indicator before removal. Install the new indicator-equipped pad in the same inner-pad position.
• Place the caliper over the drain pan if any fluid or residue is present.

Step 6: Compress the Caliper Pistons

• Place an old brake pad across both caliper pistons.
• Use the disc-brake piston compression tool to push both pistons inward slowly and evenly.
• Watch the brake-fluid reservoir while compressing the pistons. Use the brake-fluid syringe if the fluid approaches the top.
• Stop if either piston binds, tilts, or the rubber dust boot folds inward.

Step 7: Remove the Caliper Bracket

• Use a 19mm socket and 1/2-inch breaker bar to remove the two caliper-bracket bolts.
• Lift the bracket away from the rotor.
• Keep the bolts clean and inspect their threads for damage.

Step 8: Remove the Old Rotor

• Use a Phillips No. 3 impact screwdriver and 16-ounce ball-peen hammer to loosen the rotor retaining screw.
• If the rotor is stuck, thread the two M8-1.25 rotor-removal bolts evenly into the rotor’s threaded extraction holes.
• Use a 3/8-inch ratchet to turn each removal bolt a few turns at a time until the rotor releases.
• Do not strike the wheel studs or hub bearing.

Step 9: Clean the Hub and New Rotor

• Use the soft brass wire brush to remove rust and scale from the hub face.
• The hub face must be flat and clean so the new rotor does not wobble.
• Hold the new rotor over the drain pan and clean both braking surfaces with non-chlorinated brake cleaner.
• Wipe away the shipping oil with a clean disposable towel.

Step 10: Install the New Rotor

• Slide the cleaned rotor over the wheel studs and align its retaining-screw hole.
• Install the retaining screw with the Phillips No. 3 impact screwdriver.
• Torque to 10 Nm (7 ft-lbs) if your torque wrench and bit arrangement can accurately reach this value.
• Do not overtighten the small retaining screw.

Step 11: Service the Caliper Bracket

• Use the small flat-blade screwdriver to pull each guide pin from the bracket, one at a time.
• Wipe each pin clean and inspect it for rust, pitting, or bending.
• Apply a thin coat of Honda-compatible silicone brake grease and reinstall each pin in its original position.
• Confirm the rubber boots seat fully and both pins slide smoothly.
• Use the soft brass wire brush to clean the pad-clip seating areas on the bracket.

Step 12: Reinstall the Caliper Bracket

• Position the bracket over the new rotor and start both mounting bolts by hand.
• Use the 19mm socket and 1/2-inch torque wrench to tighten both bracket bolts.
• Torque to 137 Nm (101 ft-lbs).

Step 13: Install the New Hardware and Pads

• Press the new stainless-steel pad clips fully into the cleaned bracket by hand.
• Apply a very thin film of molybdenum brake pad lubricant only where the pad ears contact the clips and where specified on the backs of the shims.
• Do not place grease on the rotor or pad friction material.
• Slide the inner and outer pads into the bracket. Confirm they move without binding.
• A thin lubricant film is enough.

Step 14: Reinstall the Caliper

• Lower the caliper over the new pads without twisting the brake hose.
• Start both guide-pin bolts by hand to prevent cross-threading.
• Use the 14mm socket and 1/2-inch torque wrench to tighten the guide-pin bolts.
• Torque to 50 Nm (37 ft-lbs).
• Remove the brake caliper hanger.

Step 15: Repeat on the Opposite Side

• Repeat Steps 4 through 14 on the other front wheel.
• Use the same tools and torque specifications.
• Verify that both brake hoses follow their original routing and are not twisted.

Step 16: Reinstall the Wheels

• Place each wheel onto its hub and install all wheel nuts by hand.
• Use the 22mm deep socket and 3/8-inch ratchet to snug the nuts in a crisscross pattern.
• Use the 2-ton floor jack to lift your Ridgeline slightly, remove the jack stands, and lower it until the tyres touch the ground.
• Use the 22mm deep socket and 1/2-inch torque wrench to tighten the wheel nuts in a crisscross pattern.
• Torque to 127 Nm (94 ft-lbs).

Step 17: Restore Brake Pedal Pressure

• Before starting the engine, press and release the brake pedal slowly several times until it feels firm.
• Do not drive while the pedal feels soft or travels close to the floor.
• Check the reservoir and add fresh DOT 3 brake fluid only if the level is below MAX.
• Install the reservoir cap securely.

✅ After Repair

• ✅ Start the engine and hold firm pressure on the brake pedal for 30 seconds. The pedal should remain stable.
• 🔍 Inspect both front calipers, hoses, and the brake-fluid reservoir for leaks.
• 🚗 Test the brakes at walking speed in a clear, private area before entering traffic.
• 🛑 Bed in the pads with 8-10 moderate stops from about 50 km/h to 10 km/h. Allow approximately 30 seconds between stops and do not come to a complete stop with hot brakes clamped.
• 🌡️ Drive for several minutes without heavy braking afterward so the brakes can cool.
• 🔧 Recheck the wheel-nut torque after approximately 80-160 km.
• ⚠️ If your Ridgeline pulls, vibrates, makes grinding noises, or has a soft pedal, stop driving and inspect the work.
