Hey guys I recently bought a 225 that needs a bit of love after 112k miles. After removing the front wheels I'm met with what appear to be threaded brake pins. I've added a picture on imgur that shows how the pins have no head on either side to remove them. Has anyone else encountered this problem? www.imgur.com/a/W5dFT
Don't think its threaded, could be something home made as that surface should be smooth, anyway spray with plus gas overnight and tap with drift pin . Might be a retainer clip on inside also. Sent from my iPad using Tapatalk
thats definitly a rough and ready repair, obviously the last owner bust the pins trying to remove them last time and didn't have a new set to hand and has just found the nearest thing to hand to fit the hole in this case a piece of threaded bar or old bolt with the head removed. just have to hope he didn't try to tap the holes and screw the bar in as that could be a major pain to remove. if plus gas doesn't work try something like loctite freeze spray to break the hold.
You need a new set of pins that I think a member on here sells. You also need to hope that the new pins will now fit properly, otherwise you might be looking at replacing the calipers.
Can recommend Mr Pinks pins ! took my mechanic almost 3 hours to get "proper" pins out of mine with a proper brembo punch.. needed cutting into 3 to get them out.. and that was a 55k mile car..
Hey guys thanks for the responses, Ive ordered a punch and I already had some pins from Kamracing. I had another look to see if the pins were tapped into the caliper, it looks like they might be =( The other thing is that the paint on the ends is the same paint as the caliper? I have no idea why this might be the case but my car has had 6 owners before me.
How much thread is sticking out at the other end? Might be able to get two very slim or ground down nuts on there and wind them out with a spanner. I'd chop the painted bit off with a hacksaw first so you're not trying to thread the rusty painted end out as once you can get enough of the other end out of the caliper you can stick two proper nuts on it then give it some proper welly. It looks like they may even be bolts from the picture?
Just a thought, but if you cut say a 15mm section out in the middle of the threaded section, you could, like someone else mentioned, screw a couple of nuts on to each side of the remaining bar and then hopefully pull the bar out/push it through the calliper…..
Unfortunately I dont really have access to an angle grinder so cutting it off would be quite hard. But thanks for the response.
I was just thinking Dremel with a metal cutting disc. From the looks of that photo I would say that it’s obvious the callipers have been re-painted following the insertion of the bolt. It’s impossible to tell for certain from just the photo, but the end that has been painted just looks to be the non-head end, you may find if you reach around to the other end you may feel a hex-head or Allen-head which you could then loosen with a socket or Allen key. I doubt someone would’ve gone to the trouble of threading a bolt in there then just cut the end off – there must’ve been a little logic behind it all. Out of interest, is the other calliper the same?
Looking again at the photo, I'd say that it looks like there is an Allen-head at the other end of the bolt - you may therefore just be able to unscrew it....
