Sourcing a Rear Brake Master Cylinder??

[robm3]

Howdy all,
Any idea's on where I can source a Rear Brake Master Cylinder or what type the standard one is e.g. Scorpio etc.. As mine seems to be causing issues.
I don't want to buy the whole factory pack of clutch, front and rear cylinders, balance bar etc.. when all I need is the rear (will give the factory a call and see if they'll split a Rear out for me though, worth a try).

Do you mean the clutch slave cylinder? I haven't seen many Ultimas running rear drum brakes Let us know where you source one from if you find somewhere. I may be after one soon.

Cheers

Edited to add - I have read the post for the 3rd time and see what you mean now!!! The factory should do you one OK without needing to slit a build module. Good luck

I take it from this that you brake problem was the cylinder itself.
Is it actually seized?

You could try Partco,Andrew Page, Brakes International etc, they all provide measure and match service on vehicle hydraulic components.

Steve,
No, it's not seized.
It's sort of a deduction process. When the rear brakes are locked on the brake lights are on meaning there's pressure in the line still, this kinda counts out the calipers and points a finger at the master cylinder. The pushrod moves freely but is pitted, I'm guessing it's pressuring the line okay but not allowing a return.
Only other thing it could be is collapsing brake lines somewhere in the circuit but hopefully not as that'll be a pain to trace/change.
Cheers,
Robin.

If you have it on the bench I would take it apart and see if you find anything that should not be.
Main reason is that if it has failed due to the seals breaking up or swelling it could be an incompatibility of seals to fluid which some have experienced with alternative clutch slave cylinders.
