Porsche brake squeal SOLVED!

If you're hearing a squealing or squeaking sound from the brakes on your Porsche, but haven't seen a brake wear indicator light on the dashboard the pads may be worn unevenly and may need to be changed. That solved the issue on my 2012 Porsche 911 (991.1).
Here's a GREAT Porsche 991 DIY brake tutorial:

Thanks again for the video. Every little bit of info is helpful, I appreciate it, and what are the odds that I was starting to troubleshoot this on my 991.1 on the same day you posted this video! I pulled the back wheels off, visually inspected and bled the rear calipers. I'll watch the video you shared, but you've convinced me I need to pull the calipers off and inspect the sensors. I have the same squeal you had, except mine is a little less intense.

Glad it's helpful and I hope you find your squeal. Mine was getting really bad as you saw in the video. If you have the wear sensors that only go on one pad, it's super likely that the sensor side pad is ok and the other is worn. It's a pretty straightforward DIY job to change out both the pads and rotors though. Good luck!

That the exact same sound mine makes. Ive had them changed twice. It goes away and comes back. Wondering if your returned or not. I've heard its a performance brake thing and you need to drive at a high speed and stop to break them in.

[@AtypicalDriver]

Mine has yet to return! When they changed yours did they do both the pads and rotors?

@@AtypicalDriver have you brakes sound returned. Yeah have a gt4 and have the same sound. I brought it into Porsche and they told me it’s normal and that I have lots of life left in my pads. Mine are very bad.

[@AtypicalDriver]

@@joeylam6120 no sound has not returned, although another mechanic told me that when that happens, if pad life is still ok do a whole bunch of hard stops from around 80-100mph to knock off any glazing of the pads or rotors. Maybe give that a try somewhere safe?

@@joeylam6120 I have a GT4 as well, made the squealing sounds from day 1 of driving it off the lot. It’s extremely obnoxious and attention grabbing, more so than the car lol. I just took it in for my 1 year service and they said the same exact thing. I’ve done the braking at high speeds, it goes away for about 10 minutes to the entire day and then comes back the next.

I was hoping to see what your brake pads look like when you remove them. How many miles were on them?

[@AtypicalDriver]

Thanks for leaving a comment, and you're in luck because I still have the old pads! Here they are...I believe they're the originals so they have about 54k miles on them.

Porsche brakes squeal. I don't love that but I do love how my Porsche's stop.

[@AtypicalDriver]

Mine haven't squealed since I did this job, shit now I probably jinxed it

[@user-yo9ch3vl1j]

The sound is caused by misaligned rotor. You are doing a proper brake servicing in the video . Thats good. But Caliper pins will need lubrication too you missed that out

[@AtypicalDriver]

Thanks for watching! They're not sliding caliper pins on the 911 since they're radially mounted, do they still need lubrication or maybe just some anti seize on the threads?

[@lifehackertips]

Doesn’t work. Changed the brakes and rotors, still squeals

[@AtypicalDriver]

Oh no! Hmmm, any other ideas what it could be in your case? Assume everything is reassembled properly, spring clips in place, etc.

[@HoneyDooDoo]

Try buying lower quality brakes. High performance brakes tend to squeal.

[@lifehackertips]

@@HoneyDooDoo who buys low quality brakes for a Porsche?

[@meCmoni]

@@lifehackertips then expect squeal...
