stop using WD40. PB-blaster works very well.
hit with a hammer or as a last resort, get at it with a propane torch (just make sure all fluids are GONE!) | | | | | 08-30-2005, 04:11 PM | #4 | | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 |
Do the calipers still work with the guide bolts frozen? I thought the caliper had to slide on those guide bolts to clamp on the pads. On a side note, I know a guy selling some brand new performance ones on Ebay.  http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMESE%3AIT Quote: | Originally Posted by stormos Guys, my guide bolts on the carriers seem to be fused solid, been spraying with wd40 2 times a day for the last couple of days with little effect, any ideas? also what direction should i be turning the bolts? i tried both but its hard to work it out.....

i am talking the guide bolts onto the carriers. they'll still work, i just want them off ready for powder.
on another note the garage couldn't air blow the piston out today. aaaahhhhhh __________________

there's gotta be some type of specific penetrating spray.
WD40 is an acronym for "water displacement attempt 40," meaning that all it's meant to do is keep things from rusting. it does work as a lubricant, but not very well.
if you can't find anything i'll ask on my motorcycle forum for you. | | | | | 08-30-2005, 06:34 PM | #8 | | Senior Member Join Date: May 2005 Location: England, UK Posts: 1,288 |

is it just a matter of leverage or what? they shouldn't be put in with that much force. it's easier while still on the car, but should be doable off (i did it with the ones i bought used). as aceyx said, some penetrating lubricant/rust breaker would be best. if you have the carrier separated from the rest of the caliper, put it back into the guide bushings so you have a little more to use as leverage when trying to break them free. __________________ 1996 318ti, California package, 267k miles

penetrating oil,, some times called the penetrating lubricant. __________________

the trick with removing stuck bolts with heat is to not heat the bolt itself but heat the material that surrounds the threaded hole the bolts go into thus expanding the diameter. propane torch should provide suitable heat but be patient.use the tip of the flame and move the torch around the area to heat. don't be afraid to use some leverage either in the form of a long handled socket wrench or better yet a breaker bar.breaker bar is made to hold standard socket but has no ratcheting action. sometime you can blow out the ratchet before you can apply enough torque needed to loosen the bolt.
as always when working with an open flame take precautions . as some said earlier in the tread be aware of flammable fluids including and penetration oil use on the bolts. keep a fire extinguisher handy just in case.
liquid wrench brand penetrating oil has been around for years and work very good if you can find it.
good luck. | | | | | 08-31-2005, 06:21 AM | #12 | | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 |
watch your breaker bars; if the bolt is seized properly you can end up snapping off the head.
drilling out bolts = no fun. (trust me on that) | | | | | 08-31-2005, 07:38 AM | #13 | | Senior Member Join Date: May 2005 Location: England, UK Posts: 1,288 |

is it ok to use it on the piston aswell? as the guys in the garage could not air compress it out.... __________________

it won't hurt the metal, that's for sure. are you saying they used compressed air and they couldn't get the piston ejected from the bore? that would seem quite odd unless the pressure wasn't high enough. it does take a good bit (as well as a good seal on the hydraulic line fitting and a closed bleeder valve) to get it to pop out. when i say "pop out," i mean it. it shoots out so have a piece of wood on the other side for it to hit rather than the brake carrier or something else that might damage it. forget what psi we had to get the compressor up to for it to actually get it to move. __________________ 1996 318ti, California package, 267k miles
