Wheel cylinder seized connection

[Richardtr3a]

I need some advice on a minor technical problem. On my 3A at the rear RHS,  the hydraulic pipe fits to the wheel cylinder with a brass fitting. It will not be undone and is solid. It is now off the car and I tried to hold it in a vice but the brass pipe connection is getting damaged and is solid. There is no way it could be a left hand thread is there ?  It is now soaking in WD 40 until tomorrow. It can not be more than 10years old and heat would be dangerous.  Plumbing tools are causing damage to the brass.

I need some advice from other owners who have sorted out problems like this.

Thanks Richard & B

Its not L/hand thread but possibly been wound in too hard and the thread has bound up. Take the piston out and hold the cylinder in the vice with soft jaws to be able to get a better purchase on the fitting, you do need a proper pipe spanner to undo safely. Like this Brake pipe spanner

Stuart.

now it is off the car and held in the vice….Bit of heat.plus use the spanner type Stuart suggests.

Hi Richard,

hold your tin of WD40 in your right hand and see how far you can throw it down the garden. Then leave it there.

It is not a penetrating fluid (nor a lubricant etc etc.)

PlusGas etc is what you need.

Just for information if you suspect a nut is Left hand thread it should have a nick as in the following pic.

Don't throw your WD40 away, it is very good for dispelling water and cleaning engine compartments and suchlike. It is rubbish at releasing difficult bolts. Unlike Plusgas which is great. Apply Plusgas and give it a day or so to work.

+1 for the WD40 comments!

I have been using WD 40 for decades and it helps with all sorts of difficulties including keeping the hand saw working smoothly when cutting logs for the winter fire.

Sorry Roger I am not near your garden even if I try hard to throw it 

Thanks Richard & B

After many years of getting nowhere with WD40 I recently bought a can of Plusgas.
I have to admit that I was not that impressed. In fact I did not find it a lot better than WD40.

What I did notice though was that the Plusgas did not have the same smell as I remember from when I last used it in the 1960’s.
I wonder if it is another one of those things that for health and safety reasons has had to change the formulae.

Charlie,

The initials in WD40 stand for Water Dispersant

+1 The fact that one can quieten a squeaking fan belt most effectively with a quick spray of WD40 without the belt slipping suggests to me it is NOT a lubricant.

[RogerH]

my garage shelf contains -

3 in 1 for general lubrication of nuts/bolts etc

PlusGas or FreeWay penetrating fluid.

Engine oil (20/50 ) in my squirty can

Servisol switch cleaner

Wynns Brake&clutch cleaner

plus loads of other stuff - including WD40 (to occasionally remind me how awful it is)

You do have to be a bit careful what you are talking about with WD40.  Besides the original dewatering stuff, they now have a range of other goops with the same overall name but different purposes:

What... Like the stuff Moses used to part the Red Sea.

So what does the 40 stand for?

(And if you tell me that it was the 40TH attempt to get it right, what happened to WD1 - WD39)

Hi Charlie,

 it was the 40th formulation that did what the inventor wanted.

Got him a patent and much money for a wazzy fluid that doesn't lubricate but does displace water.

Even WD40 seems different to the original. I remember it used to leave a sort of varnish on dizzy caps and plug leads with regular use, but nowadays it just seems to evapourate away.

Today I took the  brake cylinder , with the pipe attached, to the local village garage. They said no problem and took it in. On the way home I called in and it was all finished. They would not charge me or accept a tip. After asking they explained that 

1. Cut off the pipe flush
2. Find a quality socket and tap it over the brass nut.
3. A small lever and it came out easily.

I am sure that it works well with a quality socket but my tools are not Snap On and may not stand up to the pressure. So the next move is to get the complete back axle assembly to the overhaul specialist. I am hoping that it is not serious.

Problem sorted and on to the next.
