Bleed nipple on???? brakes?

 

Ah, sorry... should have been more clear...

The Coolant nipple :broon:

 

Whats wrong with bleed nipples on brakes?:dunno:

What do you call those things on your callipers then, that you bleed the hydraulic fluid from?

 

you dont want to be snapping bleed nipples off .. right pain ..

 

Yeah, my dad has had it happen on a caliper in the past.. lucky thing is you can take that off.
Thats why Im concerned about this one...

 

For the heater matrix you mean then, give it a good soak in plusgas, this stuff is better the more its left, failing that its drilling and re-tapping im afraid.

 

I'm presuming you mean the radiator bleed nipple?
I can't help you getting it undone, but when you manage to, bang one of the mike satur replacements on it!

 

Its the one under the scuttle panel to the left hand side of the brake servo...

The heater matrix nipple?

 

Yep, its for the heater matrix, if its seized heat wont be alot of use as youll need to heat the area around it not on it. Try giving it a hit with a soft mallet, sometimes this is enough to crack the threads, or tighten befor trying to loosen, as i said plusgas takes time sometimes.

 

Yeah, just seen your previous post... Guess I'll leave it soaking a while more :broon:

 

First thing I did when I got mine was to replace it with a Radiator Bleed Screw/Nipple from Mike Satur

 

So the rad one fits the heater matrix too?

 

I brought some of this back the other week in my suitcase http://www.loctitefreezeandrelease.com/

Halfords do a version and it's probably the same thing.

 

It's the same as plumbers pipe freezer that you can buy in most diy shops like Wickes. About £6 a can iirc.

 

Had the same problem with mine being tight. nothing would shift it but when it did come free it came off with the brass bush it was screwed into. It was a new matrix after that which meant dashboard out. It was a learning experience on how to remove the dashboard but I wish it had been easier...
Also the bushing is soldered into the matrix, so not too much heat...
Good luck....

 

Have you tried slightly and i mean slightly tightening it, sometimes this can release the damn thing.

 

Yeah, I tried...
Not had a look at it again since but shall be doing something this weekend..

 

Plusgas, wait and try, if fail, try again.... took me 3 days and 8 shots of Plusgas to get mine to loosten........

Some garages have vacuum coolant fillers, they are also on sale at many car part shops, not a hard job, make a vacuum and fill the whole system, that, apparantly is how Rover filled them so if you can find a garage with one you might get around the nipple problem....

 

Hi, I had a similar experience. Finally I applied penetrating oil (socked overnight) then tried tightening the nipple first followed by fitting a good socket spanner with a long leaver then anticlockwise and it came undone.
I too was concerned with breaking the seal between the matrix and brass adaptor. Good luck
