Default Brake load sensing valve seized?

Brake load sensing valve/Brake pressure regulator has seized, so I have 'little or no effort' on the rear nearside and offside brakes.

I've drowned it in WD40 and belted it with various blunt instruments but can't seem to get it shifting, any 'tips of the trade' or have I got to shell out 70 for a new one?

I just failed the MOT on this very thing causing little effort on the rear brakes...(after advisories every year for the last 5)...bit the bullet and had the job done...so worth it.

63 odd quid plus vat from gsf. 90 quid labour at a "good but not very cheap" garage.

amazing difference to how the van stops now though...i didn't realise that the brakes could be as good as they are now.

wouldn't want to play around with the valve too much though...it's a safety critical part and could be the cause of the rear overtaking the front if it's done badly.

Relish my uno !!!!!

I bought a replacement from GSF got it home and compared it with the one that was 'seized' and it has exactly the same travel on the 'pivot' so I've greased it up and bled the rear brakes (A big air lock came out) so I'm hoping it's freed itself up with all the bashing I gave it.

Re-test tomorrow so we'll see! if it still fails I'll be off to get it done at a garage!

I'll try and get some in the light tomorrow...

Just reversed at speed (cul-de-sac, no traffic or pedestrians *pc correct disclaimer*) and slammed the anchors on and the back dipped sharply so I'm thinking the back brakes are definately working.. we'll see tomorrow.

it's right smack in the middle of the rear 'arms' with a T-peice going out to springs that are attached to the bottom of the arms (if that makes sense?)

It passed! Apparently it only has to move very slightly, I now have full brakes on the rear.
