Ask the stork to take it back.;)

Some of the old seal kits did both slave and master, on just did not need all the bits for the slave, like I said no guaranty.

The cylinder seals for your slave may well be STC 500090 from LR parts [ no guaranty] Do not pull the rod as can be a git to replace through the slave hole. To clean out the housing remove tunnel, gearstick and access plate and blast with an air line. Nice it has the bleeder extension, always...

Shure needs an inner wing to bolt that res to.

The modern made stats are often rubbish. Last year I had 3 replacements when original failed after many years. Number 1 did not work at all, 2 packed up after a month. Number 3 a new in the box original Waxstat still fine. If you want to know your actual temp fit an after market capillary gauge...

L R Center LRC2332 for a set of longer studs.

Having been involved with 4x4 trials have seen many a shaft/diff break including some of mine. Many moons ago with my series 2a I lost drive and later found I could not remove NS shaft. I had chained other end of axle to a shed stanchion and pulled on stuck shaft with a tractor! It did not come...

Try "Automobile-catalog" for info on your truck's specs. Western power one's usually have either large rear body's or hydraulic platform on them. So likely HD springs ect.

Yea I know that it is hard to measure and do it just by feel. The last time I replaced mines master I could not get it to bleed at all. Turned out the new master was gooie inside and at the first press piston stuck at the bottom though doubt it is your issue as fluid is going through. My...

Have you checked the amount of free play the pushrod to master has? It is only a very small amount but if too much no brakes. No freeplay and brakes will stick on some.

HRC1924 Lists as a front hub for Discovery 2.

Some think grease will stay in if seals are iffy, but it is not the case. The one shot stuff when warmed up will leak like the gear oil when seals are bad. Is the oil system better? Series Landy's used it and so did the early coil spring ones. Have driven both types for over 50 years with many...

You are correct Gear oil 80/90 is what mine uses being a 1990 model.

Renewing front shocks and spring pans on mine. All turret rings nuts came off with none broken [pays to oil them] One turret had a rotted out section, did not want to wait for a replacement so welded in a patch.

I used to think the same as @lynall above, However due to availability fitted alloy with plastic ends type some fifteen years ago and still good.
