Hi,

Anyone got any workable solutions to free the bleed nipple on 4 pot Brembo caliper.. it's the inside one that's being a pain. The Alfa specialist, through experience is hesitant to apply more force saying he knows it's going to snap off. Had to bleed the caliper by turning it upside down and venting through the link pipe which I thought was clever :)

If i'm successful in removing the cleanly are there replacements available, might as well get them all sorted if it's servicable?

Cheers

Can't help you with removing them, other than usual heat, plusgas, or slightly tightening before slackening.

Should have thought replacements should be easy enough, think there's only a couple of sizes for bleed nipples - happy to be corrected though.

Surely there's a better option for stainless or something to stop them corroding in, or snapping.

Cheers.. keep reading about plusgas.. where can this be purchased from, never seen it in the usual places like halfords?

I only ever find it in Euro Car Parts, and not in my local one.... Halfords sell their own dismantling spray, but I'm afraid nothing comes close to Plusgas in my opinion.

Found a great way of doing this a while back after I had the same problem. Plus gas will be fine although I used WD 40 Specialist Fast Release Penetrant (available in Toolstation). Please note though this isn’t the usual WD40 that comes in blue tins.

You need to heat the nipple with a blow torch carefully to get it pretty warm, remove the flame and spray the WD40 on the bottom of the nipple thread. You’ll get plenty of smoke, allow to cool and then repeat the process of applying heat and then spraying the WD40.

After a few cycles of heat/cool try the nipple, repeat until it loosens off. This process has worked for me every time since I found it.

The rapid cooling draws the WD40 down the thread in a way just spraying it on doesn’t. Just be careful you allow the nipple to cool down and WD40 to soak in so it doesn’t flash off when you apply the heat again.

Worth using a socket on the nipple as well instead of a spanner, bit of patience and it’ll come out. Good luck.

As far as replacements go, I recently got new ones for my Twinnie from Alfaworkshop. Give them a call.

Thanks guys, I'll give this trick a go, got to be worth it rather than buying new calipers..

Anyone know the size of the bleed nipples.. Alfaworkshop have some but they're 2.0 type calipers. I'm not sure but I think mine are 305mm 4 pot Brembos and maybe they're used on other vehicles?
