Help please!

I have a 53 TT Mk1 V6 DSG with 65k miles
My local garage can't undo the front bleed nipples (I trust the mechanic): they did the rears, no problem

He has offered two solutions: 1. Take the calipers off, drill the nips out, re-tap and re-place or 2. New calipers

Are there any known trick to free the bleed nipples or am I in the Sh1t?

Thanks in advance

Worst job on a car ever buddy. They dont want to do incase they break them. If you trust them, say try your best and if they break they break and retap them. You might be lucky and they not break, but I doubt it, they are buggers!

Thanks Bikerz

Can you recommend a source for me to price up a pair of new calipers so that I can compare with the "break, drill, re-tap, re-place" option?

Thanks in advance

Look up 'trade parts specialists', Audi parts at trade prices.

or GSF, or EuroCarParts.

To be honest, id say the re-tap from your mechanic will be cheaper.... theyre hellish expensive calipers.

Alternatively, look around for a breakers that has a V6 TT, but you might well end up with the same problem.

Sorry bud.

A small tip for easing them might be to very gently tighten and release, tighten and release, tighten and release but only in tension, gently enough to not snap them off completely but firm enough to make tiny movements acting in the thread.

You could try applying a bit of heat localised near the metal around the nipple but not on the actual nipple.
I think the caliper is aluminium and therein lie the problem, the threads get 'furred' up and act apon the steel nipple.

With a liberal spraying of a good freeing oil like duck oil or WD40 (obvioulsy not while you have a flame near it) plus the gentle tighten/loosen motion, you might get lucky.

Worst case is they break off and you have to drill them out.... which is pretty much what you are going to need to do anyway.

Aluminium expands faster than steel so hopefully with heat on it, you will expand the caliper away from the steel nipple.

If it were me, i would do that and bear in mind you have not much else to lose.... if they break off, you wont get fluid leaking, just means you definitely have to drill 'em out.

Iam liking your advise, Being a plumber I would be suprised if audi used steel bleeders on aluminium calipers as dis-similar metals tend to cause electrolyisis (corrosion).The wd40 with heat applied is a great idea.You could even spray them up the night before applying heat.
