Im looking to upgrade to is350 brakes and will be purchasing used calipers. Should I be worried about the mileage on the calipers. Obviously lower is better but above how many should I be steering away from. Are calipers a part that I should worry about failing? Thanks in advance.

 

There are parts on all calipers that can fail, but the FRONT IS350 calipers seem to hold-up well to mileage. Not really any issues with seizing up or faulty piston seals or such things. Just look for lower mileage and any signs of brake fluid leakage.

I've not had to research this swap myself, as I have an IS350 already; but I believe you will need matching rotors, of course brake pads, and I also believe the IS350 dust shield is needed too.

 

just get the rebuilt version which approx $130 each

 

do u have a link for this^? Thanks

 

thanks for the response! got the rotors on the way

 

 

are these aftermarkets or just oem parts that have been rebuilt? thanks in advance

 

I would try rockauto :

Are the is350 calipers same size as isf?

 

Seems like aftermarket, bu not sure.

 

^^^^^^^^^^^^^This

no...

IS350 has a lexus 4 piston brake. ISF has a 6 piston brembo brake

 

Anyone can confirm if these fit Lexus IS250??

 

I can confirm these will fit. I'll order these when is time to replace pads

 

Did you have to buy new rotors, the pads, brake hose, and shim too since I think IS250 parts are different from the IS350.

 

yes to some, there are a lot of DIY with 350 calipers upgrade. search
