Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Temporarily admitting defeat, I put the old rotor back on with no problems and tightened the phillips screws and went on with my life.

I used a deadblow hammer to try to nudge the rotor flush, but no luck.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I can't get my new PowerStop rotors to fit the front of my 2004 Cabriolet. All the dimensions match up with the existiing rotors, but there remains a 1/16" gap between the hub and the inner face of the rotor. Disturbingly, the rotors have stickers that say 'Rear Driver's side' and 'Rear Passenger Side', but they are definitely not rear rotors. I only tried the driver's side,Rotor assuming the same would happen if I tried the other one. I used a deadblow hammer to try to nudge the rotor flush, but no luck. Temporarily admitting defeat, I put the old rotor back on with no problems and tightened the phillips screws and went on with my life. I'm planning to put some FEAL coilovers on in a few weeks, and that would be a good time to install new rotors. So, here's my question (s). Did I miss something? Has anyone else had a problem installing PowerStop EBR834 XPR rotors? I called the manufacturer and the customer service rep had not heard of similar complaints (although she did apologize for the mislabeling error). I've done lots of brake jobs on similar vehicles and never had this problem. None of the threads or YouTube videos on Porsche brakes gave me a clue as to what I might have done wrong. Thanks in advance for not replying, "Just take it to the dealer and give them $2,000. They'll know what to do!" Here's a pic for attention. You can see the gap where the rotors don't sit fluch by looking at the bolt holes.

POST 2Original post

QC on Powerstop stuff has gotten worse since pandemic, I'd fight for a return or straight-up chargeback if they don't cooperate. If they need proof, bust out the calipers and you'll figure out exactly where the new rotor is fouling on the hub.
