Please identify my brakes

What have I bought ?
Ive got a Series bitsa landy. Brakes are dire.
Had a look, will need a new master cylinder, all shoes, and 1 of each pistons
Looking at parts suppiers online the brakes are described by the vehicle the might once have belonged to, eg LWB S2 or whatever. Ive no idea what to order.

Master cylinder - 7 inches long, dual circuit, Girling and a number on the side which is hard to read - something like 74390?93

Front brakes - 11" drums, 2" shoes, 2 single pistons
one piston marked Girling and maybe 309460

Rear brakes 10" x 1.5", the wheel cylinder has 2 pistons. Could be marked with AR21

a few pics would help

having a filth-proof camera while taking drums apart would be handy too

Sounds like 1980-on 88" or standard 109".

Have you compared them to the parts book? Plenty of links on here to parts book and land rover manuals or try
pdf Land Rover Manuals | Landroverweb.com

Never seen 2 piston rear drums before?

I think he means 2 pistons in one cylinder, standard then.

oh aye, see what you mean there

Good link ! Thanks !
I hadn't found those, will be very useful

yes, there is a servo, I think I have the longest of the series 3 dual circuit masters

stick pics up of the vehicle, exterior, interior and engine bay and the brakes

will do, when I get things apart again

or if you want to identify your bitsa, if you are unsure if it's a s3

"interesting".
The pistons on the rear drums have metric threads. I found out by failing to fit the replacements I'd bought. Could they be discovery, defender etc ?
Once identified, perhaps there will be a choice of bore sizes like the series has between SWB and LWB
Pictures soon

Metric just means they are later (mid 70s, I think) s3 brake pipes.

i desperately needed a rear cylinder for me 86 110.. think i found one from unipart and it came with the wrong thread on it.. i couldn't wait to get the right one and luckily i have a bunch of various unions, so i just fitted cut the pipe and fitted the thread it wanted.

these fitted perfectly, though of a slimmer design

so you never know!

I'd though of changing the pipe ends, havent got a flaring tool. May be scouring evilbuy

Has anyone got a flaring tool I could borrow or buy ?
