2004 Jeep Grand Cherokee Accessories & Parts

I purchased these new last year on or around 07/2021. Just last week I had one of the pistons seize up on me while driving and my vehicle shaking violently because my caliper was locked up. Upon removal & inspection, I had a tear in the rubber dust boot for the piston. I came to check for any warranty info. Since it hasn't been a year yet. Only to be told 60days or 3000 miles!! WtF is 3000miles for a caliper?! Because I purchased the front calipers separately. I'm not covered by the 3yr/ 36,000 mile warranty whichever comes 1st. No instead I'll have to eat it! All I have ever bought was Powerstop for my old Jeep, my current Jeep has Powerstop cross drilled rotors all around w/Z34 pads, and my wife's Nissan Maxima has the same! I will NOT be purchasing ANY Powerstop products from here on out!! Powerstop you SUCK!!
