uttak IS250

I used standard copper vaseline grease on the rear calipers. Nevertheless on front I tried to use ceramic grease similar to product in link below, but from local producer. So far so good... https://www.permatex.com/products/lubricants/specialty-lubricants-brakes/permatex-ceramic-extreme-brake-parts-lubricant-2/

Yes, I changed it to the shine and apply good grease. I'll check and grease it every 6 months (summer / winter tires exchange). I bought this car some months ago therefore I have still something to do...

Yes, it doesn't take long but you paied 400 lb, I paied one bottle of whiskey :-)

Dear all, I did it. I have Lexus IS 250, 2008. Rear calipers were totaly seized. I tried to use different oils, lubricants, break fluid, small hammer, big hammer... Only what can help you is heating. Electrical heating gun is to weak. You need oxygen-acetylene burner and gently hammering in correct place and direction.
