Hey Guys
I am doing a brake job on my 2014 S Clubman and have the calipers off and am trying to remove the old rotors. As you know each is held on by a T50 Torx bolt that is not supposed to be on all that tight. So imagine my surprise that I can't get either of them off (one on each of the two rear rotors). I am a bit baffled as to what to try next so any help would be greatly appreciated. Here's what I have tried so far :
1. Soak the bolts with PB Blaster penetrating fluid overnight.
2. Manual impact driver
3. Air tool impact driver (90psi) tool rated at 350 ft-ibs
4. Took a torch to the bolts to see if heat/cool cycle would help
5. Tried tightening (CW) first to see if that would break the stiction.

I can't think of anything else to try apart from taking it to the shop and pay a lot of money for doing what should be an easy job. Looking for inspiration - PLEASE!
Cheers
Ken

 

Don't pay a lot of money... Just keep trying. You can always bust out the drill and just drill them out. My big tip would be to hit the rotors HARD with a hammer right where the t50 bolt is. Strike it a BUNCH. The impacts will break apart the rust-- then go ahead with your above methods. REMEMBER real mechanics have oxy acetelene torches and they get stuff RED HOT. Most home mechanics will barely torch something and think it did something. This would not take a real mechanic long at all to deal with you are likely just not being aggressive enough. Hope that HELPS. HIT THE CRAP OUT OF THE ROTOR WITH A HAMMER FIRST THEN TRY.

 

Thanks Cali, I often tend to err on the gentler side when dealing with mechanics. It’s something to do with early experiences with 80’s Japanese motorcycles which often used steel bolts and aluminum heads 😬. I’m going to try again - with a bigger hammer!
