How to Replace 2008 Honda Accord Front Brake Pads & Rotors

Identify Your Honda Accord Year and Engine

The brake system consists of four main components: brake rotors, brake pads, the caliper assembly (brake caliper + caliper bracket), and the hydraulic system.

Honda Accord brake system specifications vary significantly across generations, and getting the model year wrong can easily lead to purchasing the wrong parts. That's why YouTube repair videos typically split 2008-2012 and 2013-2017 into two separate series — they're entirely different generations, with major differences in engine and brake rotor sizes.

(TRQ has published replacement videos for both eras on YouTube.)

According to the haccord service manual, the 2008-2012 models are the 8th-generation Honda Accord with the North American chassis code CP. The front brake rotors on this generation come in two thickness specifications:

• 2.4L 4-cylinder models (LX/EX/SE): Honda used two OEM caliper suppliers for this generation — Nissin and Akebono — and the corresponding rotor thicknesses differ. Nissin calipers pair with rotors approximately 28mm thick, while Akebono calipers pair with rotors approximately 23mm thick. Nissin calipers have the brand name clearly printed on the body.
• 3.5L V6 models (EX-L/Touring): Rotor thickness is 28mm. The V6 engine produces more horsepower and the vehicle is heavier, requiring a larger brake rotor to provide sufficient braking force and heat dissipation capacity.

The 2013-2017 models are the 9th-generation Honda Accord with chassis code CR. The chassis and brake system were completely redesigned, and parts are not interchangeable with the 8th generation.

For more detailed brake rotor diameter and system specifications, you can refer to the official Honda brochure archived on auto-brochures: 2008 Honda Accord brochure (PDF)

Therefore, before purchasing rotors and pads, always confirm the exact vehicle trim level, and pay extra attention to the engine configuration. More power requires stronger braking capability, and more kinetic energy must be dissipated during braking. A rotor's braking force and heat dissipation capacity are directly tied to its diameter and thickness.

Pre-Replacement Preparation

Tool Checklist

For disassembly and replacement:

• Floor jack
• Jack stands
• Impact wrench / impact drill + compatible sockets
• Socket wrench set: 12mm (caliper guide pins), 17mm (caliper bracket), 19mm (lug nuts)
• Torque wrench
• Rubber hammer
• Zip ties + scissors: for hanging the caliper to prevent strain on the brake hose
• Brake piston retraction tool: if you don't have one, you can rent one from AutoZone for roughly a $60 deposit. This article only covers front brake replacement — front brake pistons press straight back in, and a C-clamp paired with an old brake pad will do the job. For rear brakes, the 8th-gen Honda Accord has an integrated electronic parking brake, so the piston has grooves/teeth and requires a specialized disc brake piston wind-back tool (cube tool / wind-back tool) that engages the grooves and rotates as it presses. Never force it straight back with a C-clamp — you'll damage the internal spiral mechanism.

For cleaning and lubrication:

• Wire brush
• Brake cleaner
• Brake lubricant

For personal protection:

• Oil-resistant gloves + safety goggles

Check the Fluid Level

Many DIYers skip this step and jump straight into disassembly, but strictly speaking, it's a necessary safety procedure. For more background, see our guide on changing brake fluid when replacing pads and rotors.

(Screenshot reference from an eBay store.)

First, open the hood and locate the brake fluid reservoir, usually near the driver's side firewall. The fluid level should sit between the MIN and MAX marks:

• Level near or above MAX: Use a syringe to siphon out some brake fluid. As old pads wear down, the piston extends and the reservoir level drops accordingly. When you press the piston back in, the level will rise — and if it's already high, it may overflow.
• Level below MIN: Top off with brake fluid to near the MAX line. Note that brake fluid is hygroscopic and quickly absorbs moisture from the air once opened, so use it promptly.

Additionally, we recommend testing the brake fluid moisture content with a brake fluid tester. If the moisture content exceeds 3%, replacement is recommended — water lowers the boiling point of brake fluid, which can cause vapor lock and a spongy brake pedal under high temperatures, and can also corrode internal brake system components.

Step-by-Step Replacement

Lift the Vehicle and Remove the Wheels

Lift the vehicle with a floor jack, positioning it at the manufacturer-specified lifting points. Once raised, place jack stands at the designated support locations, then slowly lower the jack until the vehicle rests fully on the stands. Never work under a vehicle supported only by a jack.

Then use a socket wrench to loosen the lug nuts (19mm socket), following a star pattern when loosening.

Remove the Caliper, Brake Pads, and Caliper Bracket

Remove the caliper guide pin bolts and lift the caliper off the bracket (12mm socket). Hang the caliper from an upper suspension component using zip ties or a bungee cord.

• Never let the caliper hang freely — this can damage the brake hose or the caliper itself.
• Make sure the brake hose is not overstretched or twisted during hanging.
• A detailed discussion of brake hoses and the hydraulic system will be covered in a future dedicated article.

With the caliper removed, take out the brake pads from the bracket. The pads typically rest directly on either side of the rotor and can be simply pulled out once the caliper is removed.

Finally, remove the bolts behind the caliper bracket (17mm socket) and take off the bracket.

Spray some WD-40 (more advanced users prefer PB Blaster, which has stronger penetrating power) onto the rotor set screws, then try to unscrew them. If the rotor itself is stuck due to rust buildup on the hub, gently tap around the edge of the rotor with a hammer (don't overdo it) to break it loose, then slide it off.

Once the rotor is off, clean rust off the hub assembly with a wire brush. Wipe it thoroughly with a rag afterward to prevent future rust issues.

Place the new rotor face-down first (the side shown in the photo is reversed). New rotors are coated with rust-preventive oil during packaging and shipping and must be thoroughly cleaned before installation. Spray with brake cleaner (available from brands like WD-40 Specialist and others) to dissolve and remove excess grease and debris.

Then flip the rotor over — it's critical that the bolt holes line up correctly with the hub. Spray another round of brake cleaner on this side as well and let it soak while the grease dissolves. Wipe it clean with a towel.

(Both sides get cleaned — the first side was sprayed while the rotor was face-down.)

Pull the guide pins out of the caliper bracket. Wipe off old grease with a clean rag, then apply a fresh coat of brake lubricant to the pins, making sure to cover the entire surface evenly. Reinsert them into the bores, making sure to expel any trapped air. Next, remove the brake clips, clean both clip channels with a wire brush, then reinstall the clips.

Note: the two guide pins are usually different (designated A and B), so don't mix up the order — their shapes may differ.

Place the caliper bracket back over the rotor and thread in the mounting bolts. Generally, start with the upper bolt first, then tighten them down securely with a wrench.

Next, install the brake pads. The wear indicator must face inward (toward the piston), and the side with the A-Premium logo faces outward.

Retract the Piston and Install the Caliper

Cut the zip ties holding the caliper. Before retracting the piston, open the brake fluid reservoir cap under the hood and check the level — if it's near the MAX line, siphon some out with a syringe to prevent overflow when the piston is pushed back, which can corrode paint.

Use a C-clamp or a specialized piston retraction tool to press the caliper piston slowly and steadily back into the bore (placing an old brake pad between the clamp and piston prevents damage to the piston face).

Once the piston is fully retracted, slide the caliper smoothly over the guide pins until it seats fully, then secure it.

The brake rotor and pad replacement is essentially complete at this point. Reinstall the wheel (lug nut torque is approximately 80 ft-lbs — over-tightening can cause brake vibration).

Before you hit the road:

• Pump the brake pedal: Press the brake pedal firmly and repeatedly until it feels firm (no longer sinking). This pushes brake fluid back into the caliper and seats the piston against the new pads. Usually takes 5–10 pumps.
• Bed-in procedure: On an empty road or parking lot, accelerate to 30–40 km/h, then brake with moderate force down to near a stop (don't come to a complete stop). Repeat 5–8 times. This evenly transfers friction material onto the rotor surface, creating a stable, uniform brake layer.
• Before normal driving: Confirm the brake pedal height is normal, there are no unusual noises, and braking force feels consistent and stable. Avoid hard braking for the first few hundred kilometers.
