Is the master cylinder leaking fresh fluid ???
From the pics doesnt look to fresh,paint already lifted
Looks like typical early patrol pic

How much fluid are you goin thru ??
Top up daily,weekly,monthly ect
Options are,
Either buy a kit and rebuild the brake master cylinder yourself
Pay someone to do above
Buy a new master cylinder and fit yourself or pay someone to fit
Either way the full brake system will need a rebleed
Its not a 5 min job
Cost,
Well that depends on ,parts and labour costs,and what you can or cant do

I had drama's with a broken cap a few years back hence the old lifted paint,But it is leaking fresh fluid, I've found that i'm refilling it once a fortnite or so, Got no prob's giving it a crack (changing the whole unit that is) i'll get a whole new master just wondering if there's any tips for things i need to do or lookout for, Thanks for your input its greatly appreciated...

It's a fairly straight forward job, make sure you have a good set of pipe spanners the right size (pipe spanners llok like ring spanners with a small section of the ring cut out to go over the pipe).
Remove as much brake fluid from the reservoir as you can.
Remove the brake lines from the master cylinder.
Undo the bolts holding the cylinder to the booster.
Fit the new cylinder and reconnect brake lines.
Bleed the brakes.

Easy.

Yeah fairly straight forward as Tony mentions
Just have a container of water handy
If ya get any brake fluid on the paint work
Wash off straight away

A few more Tips.

Brake fluid can be removed from the reservoir by using a rag (it will soak into it)

Only by good brand pipe spanners as the cheaper ones will do more harm than good, not to mention damage.

The old Sidchrome's will do the trick, Somthings, Like tools you can't afford to cheap out on.

Another two tips, keep water away from breathholes on reseviors, and use the correct type brake fluid for you model patrol.

You can use dot 3 or dot 4 brakefluid, you can go a higher number brake fluid than the OEM spec's but not lower.

You can also get air locks in the load proportioning valve, if you end up with a spongey pedal, try bleeding the valve and then the rear brakes.
