What’s the difference between 04465-07010 and 04465-07011?

Toyota brake pads 04465-07010 and 04465-07011 look identical, but if you check the Toyota parts catalog you’ll find they don’t supersede. However, if you enter either part number into an aftermarket parts catalog like Worldpac or IMC, you’ll find they both convert to the same aftermarket part numbers, at least for every instance I’ve found so far. So what gives? What’s the difference in the pads? Are they just made for Toyota by different manufacturers or is there actually a difference?

Pad dimensions

The pad backing plates are exactly the same. There is no difference whatsoever in the sizing on these pads. The thickness of the friction material is the same, and the markings on the back of the pad are the same, almost.

Friction material

Both pads have a friction rating of FF. Brake pad friction ratings range from C to G. Each letter represents a different coefficient of friction. The letter F represents a coefficient of friction no less than 0.35 and no more than 0.45. The first F in the FF indicates the pad’s cold performance. The second F indicates the pad’s hot performance.

0.35 – 0.45 is considered the ideal coefficient of friction for a passenger car. An FF pad is able to perform well when cold and when hot, which is exactly what you want in a passenger car, since most people don’t want a car to stop poorly when they first start driving, or for the brakes to fade after going down a long hill. I’ve actually never seen a passenger car brake pad with anything other than an FF rating.

Immediately following the FF designation printed on the pad is an A24 on the 07010 and an A23 on the 07011. This I suspect is the difference between the two pads. I believe it to be a manufacturer’s designation of a particular friction material compound.

What do they fit?

I think the pad fitment is the biggest clue as to whether they’re different or not. Here are their applications:

  • 04465-07010: Fits the Toyota Avalon (2009-2016) and Toyota Camry (2009-2017)
  • 04465-07011: Fits the Toyota Camry Hybrid (2012-2015)

The 07011 only fits on the Camry hybrid and I’m sure that’s why the pads are actually different. Toyota hybrid vehicles have unique conditions for the brake pads. When braking, the friction brakes may do some, all, or none of the stopping. The hybrid control ECU will attempt to do as much braking as is possible with the MG2, the larger of the two motor generators.

What’s different about hybrid brake systems?

The primary advantage of hybrid vehicles is regenerative braking. Braking is done with the electric motor, which generates power and stores it in the battery pack for later use. However, sometimes the hybrid system can’t use the regenerative braking to slow or stop the car.

Under 5 mph the MG2 cannot provide significant brake force, so 100% of the braking is done by the friction brakes. Then, if the HV battery is fully charged, regenerative braking cannot be used. And finally, there is a torque limit to the MG2’s braking capability. If the driver wants more stopping power than the mg2 can provide then it will mix with the friction brakes to provide the necessary braking.

So why would a hybrid vehicle need a different friction compound?

I’m not an engineer and I don’t really know, but here’s what I suspect. When the vehicle is braking under 5 miles an hour it’s not making much noise and a break squeak would be really easy to hear. So I would guess that the compound is going to be tailored for quiet squeak-free operation. The other difference might be that the compound is designed to operate a little bit better when cold, since part of the braking load is going to be taken up by the regenerative braking system.

So what about the aftermarket pads?

As I mentioned earlier, the aftermarket catalogs offer the same brake pads for both part numbers. How is this possible? Well, in the end brake pads are brake pads. Any modern brake pad will stop your car. However you may notice that your brakes don’t work really well cold, which is a complaint I’ve heard with many aftermarket brake pads. Or you may notice that the brakes tend to fade a little bit more when you drive down long hills. but the most common complaint by far is brake noise.

This is why we buy Toyota brake pads whenever possible. On some older vehicles we no longer stock the Toyota brake pads and neither does the dealer. On these vehicles we will get aftermarket brake pads sometimes so the car can be completed same day. Typically we’ll go with a aftermarket brand used by the vehicle manufacturer such as Akebono. However just because Akebono made the original brake pad for Toyota it does not mean their aftermarket offering will have the same compound used by Akebono/Toyota on the original pad.

So what’s the bottom line

Could you use these pads interchangeably? Yeah probably, but they’re roughly the same price and why not put the correct pad on the car so that you take advantage of the engineering effort Toyota put into matching the friction material to the application.
