Rear brake caliper slide pins T-55 Torx

Hi Lukas,

Are you trying to remove the bolt from the slide pin that holds the caliper on or the actual slide pin from the caliper bracket? Picture of the caliper bracket below.

I assume you are trying to remove the actual bolt since you mentioned the T55 bit. If this is the case, more than likely this bolt is cross threaded which means with the repeated heat cycles the bolt has gone through it may not come out.

You can try to heat them with a small plumbers torch but just make sure you remove the brake line and drape everything you don't want to get hot with a welders blanket or some other heavy fabric so they don't get hot. Lastly keep a fire extinguisher close because you don't want to get caught off guard with some oil you didn't see. This should be a last resort because anytime you are dealing with open flame around your vehicle, it is not good to be unprepared.

The only other suggestion that I have is you will need to grind or cut the bolt head off so you can wiggle the caliper off the bolt. Then most likely you will need to replace the caliper bracket because I doubt you will get this out of the bracket.

Let me know what you think and I can see if I can come up with other ideas if you don't feel comfortable doing these. Unfortunately, we are scrapping the bottom of the barrel because you named most of the easiest and most successful techniques. Thanks.

I am sorry you are experiencing this. The unfortunate thing is these are not typically that hard to remove. This is why it was not mentioned in the video. They are simply tightened to the proper torque spec. Most mechanics just tighten them as tight as they can with a hand ratchet.

Hopefully someone did not use thread locker because that is not needed as I have done thousands of brakes jobs and never once put thread locker on these bolts.

I suspect it is one of two things. They have been removed previously and potentially cross threaded and are now seized. Or they have been heated so many times by normal break operation that the dirt, grim, and rust on the threads has seized the bolt tight. Normally we put a small amount of anti seize gel on the threads when reassembling them so this exact issue does not happen.

The techniques I mentioned like the torch are not standard tools needed to do this job so they would not have been mentioned in the video. They are techniques for removing seized bolts that you happen to have on this specific part. Heating a seized bolt would apply to any seized bolt because what you are doing when you heat the metal is expanding it and that will release some of the tension that surrounds the bolt.

Please let me know if I can assist more. Again, sorry this has been such an ordeal.

Sounds great. Thank you for the kind words. Please make suggestions of things you would like to see if it is not on here and we can definitely pass it on.

Keep me updated. Good luck getting it off.
