Likely just casting info and if they are the same you should be good to go. Pads fit the same, locate the same, mount the same, use them.

If the bracket has the 32 casting, that should be a US-spec caliper. Canada-spec (and US before 2009) would have a 28 casting.

That said, I don't think the 7D/5S will matter as long as they are the same otherwise.

Either that or someone simply installed the wrong brakes at some point. If you're interested, shoot me a PM with you VIN and I'd be interested to look at the details of it.

Your car is definitely 100% a California car, and not Canada-spec. All IS's are made in Japan, and Canada-spec refers to vehicles sold in Canada.

You car:

2009 IS250 RWD Sedan
Destination: USA
Colour: 077 Starfire Pearl
Interior: LA21 Black Leather
Production Date: 06/29/2009
Date of First Use: 09/04/2009
Accessories/Packages:
EF: Rear Bumper Applique
GN: Cargo Net
LM: Trunk Mat
LR: Rear Lip Spoiler
PT: Premium Package
WL: Wheel Locks
Z2: Preferred Accessory Package

There's no question that from the factory, your car came with the 32 mm front brakes. Everything in your picture is 2009+ USA-spec, 32 mm. The rotors aren't the only thing that's different, and it's actually pretty easy to visually see the difference if you know what to look for.

2006-2008 USA-spec and Canada-spec, 2009-2010 Canada-spec AWD, 2009-2013 Canada-spec RWD w(28 mm Rotors):


2009-2013 USA-spec, 2011-2013 Canada-spec AWD w(32 mm Rotors):


Your caliper bracket is for a 32 mm setup, the 28 mm pads won't fit that bracket, and you can see in your picture that they are 32 mm pads.

Don't know what was going on, and I'm sure something was rubbing, but I don't think it was because you had the wrong rotors. Perhaps the wrong calipers or something else was going on?

Did the smaller retaining clips fit snug on the caliper or were they kind of loose?

Midway I'd say. They'll stay on the bracket, but can easily be knocked right off.

Hey Jeff, was wondering if you can help me. I own a Lexus IS250 2009 RWD. I am trying to replace my brake pads x4 (front/back), rotors x4, calipers x2 (rear); I am very new at all of this but I was researching and decided to swap all of these parts myself as the internet said it was not mechanic worthy and technical. Then I came across this forum.. and saw US vs CAN rotors and their different sizes. Can you tell me if my car is US or CAN if i give you my VIN? Thank you so much and I GREATLY appreciate it.. I also created this account and am brand new to this site. I dont even know how to PM...

I plan on swapping everything mention above as my rear caliper has seized.. other than brake pads, rotors, calipers.. what else do I need to order? is caliper bracket needed to be ordered? rear pins that hold the brake pads in place? bolts? Thanks again.

All IS models are made in Japan, whether the car is Canada-Spec or USA-Spec depends on the destination of the car. If your speedometer is in km/h and your climate control in °C it is almost certainly a Canada-Spec car, if it is in MPH/°F, it is likely a USA-Spec car.

If you PM me your VIN, I can certainly verify that for you.

Canada-Spec IS250's use the same brakes from 2006-2013 with the exception of the rear brake caliper which uses a larger mounting bolts models produced after December 2012.

Up front, 2006-2013 Canada-Spec IS250 is the same as 2006-2008 USA-Spec IS250 with 28mm rotors and high-friction pads. 2009-2013 USA-Spec uses 32mm rotors and low-dust pads.
In rear, 2006-2010 and 2011-2013 without Sport Suspension are all the same (with the exception of the rear caliper bolt change), 2011-2013 with Sport Suspension use vented rear rotors and pads from the IS350 with unique rear calipers (IS250 piston size on IS350 rotor size).

Thank you so much Jeff, you sir are a boss

Has anyone upgraded the front calipers and then swapped the oe 250 front 2 piston calipers to the rear replacing the 1 piston? What can be done with these extra front calipers laying around? I haven't been able to figure out the correct question phrasing or comprehend how to read the lexus website parts pictograms to get the measurements and dimensions of the bolt holes online to see if they would line up or if a bracket swap would suffice relative plug and play ease.

Thanks in advance! Really appreciate your depth of knowledge with these cars. I hope to pull the potential out of this pig little by little.

The IS250 uses 1 piston front calipers, the older IS300 used 2 piston, and the IS350 uses 4 piston.

They won't fit in the rear, and even if they did, it would be a bad idea. The brake biasing of the car is primarily attained using the piston size and rotor diameter dimensions. Putting the larger front caliper onto the rear would give you a massively incorrect brake bias.
