Has anyone got any tips on getting this out without damaging the the threads in the caliper. Was going to bleed my brakes and the bloody top sheared off when trying to loosen the bleed screw

Go to Bummings and buy a set of easy-out bits. Give it a good soak in brake cleaner beforehand.

You will probably have to drill a small pilot hole first to help the easy-out bit get some purchase.

Where SOR are you? I have screw extractors here and I'd get the caliper off to remove it, if it was mine I'd be cleaning it throughly to ensure no swarf falls back into the caliper.

Cheers for the replies.

I am in Kelmscott. I did look prior to posting on here and read some bad reports about the screw extractors and how it can expand the stuck part up more as you tighten the extractor into the hole and it can snap off the extractor giving you even more shit to sort out. Have you had any success in this particular situation before using the extractors ?

If its snapped trying to undo then its fairly seized. You would be very lucky to get it out with an easy out. Unless it was over tightened and thats how it was damaged.

Only option is to hit it with some heat and an extractor. If that doesnt work then you will have to drill it and replace the thread with a helicoil.

Nice list of cars in your sig, I bought an RS2000 new in 79, I think I've still got the original recipt somewhere, I sold it 12yrs later for what I paid for it, great little car, also had 4 other Escorts.

Remove the caliper. Soak the area in a penertration spray for a while. Then get a very small center punch and hammer the left over part. Hit it off center and at an angle so that the force applies a turning motion to the left over threaded end. This combined with the impact should get it out. Its the same process used to undo shear-bolts on steering lock/columns.

You could also try heating the surrounding section of caliler with a pencil torch before doing it.

If all else fails, drill it out and re-tap it at a larger thread and instal a larger size bleed fitting. The bleed fittings in my Wilwoods are interesting in that they have a 2 piece arangment. So if this happens it looks easy to unscrew the entire thing and replace. And you wont ruin the actual caliper threads as they arent the ones that you turn to open the bleed.
