Brake load sensing valve linkage stiff

[The Mighty Elvi]

As above..an advisory on my MOT this morning. Can anybody fill me is as to what this is, where it is, how much to replace, can I do it myself and is it dangerous if it is stiff.

Cheers

look under the car in front of the passenger side rear wheel, its under there.  spray it with penatrating oil whilst wiggling it, then dry it off and give it a going over with some grease. keep this up every now & again and it will prolong the life of the unit, but it might be advisable to just replace it. this is your call based on the condition of it .

I've seen them seized solid before, but never had to replace one, unless it was leaking.
Use plenty of wd40, and give a few good whacks on the lever with a rubber mallet, then some more wd40.

are these built into the mk3 16v abs units? just as i disconnected mine as i have fitted the mk3 abs unit (abs not connected up yet) and the mot man said i need to take it off as if its there he has to test it but if its not he doesn't.

sorry for the hijack
i was under mine today and noticed that on the load valve the lever that is on the unit moves with no resistance and the spring also moves freely as there is no tension on it does this mine is shot
cheers

mine is like that richard s. mot bloke gave me advisory and said part of the arm was broke. i havent looked into it yet. i thought it was missng another returm spring?

[rubjonny]

if the car has been raised/lowered the arm needs adjusting. i set mine so when the car is sat on level ground the slack is just taken out of the spring

if you look at the bracketry where the spring is bolted to the car is a slotted hole, loosen the nut/bolt and adjust to suit. if its lowered really far there may not be enough adjustment, in this case I have seen people stretch the spring, but its not easy.

the guy in question used a widowmaker jack, held inside a wheely bin so if it pinged off it wouldnt go thru someones window or summat
