Hi all,

Recently had my brakes failed and I quickly got a local garage to put a new master cylinder on and that fixed it but they explained my brakes were so crap due to the servo being on its way out.
So I want to replace it but can't work out which one it is, or if it matters (type 80 or type 50) it's a 1988 110 V8 which makes me think it's a type 80 but actually it seems like a type 50 on at the moment.
Which part should I get to replace it or will either work stc2878 (type 50) nrc4772 (type 80).
Thanks for any help.

First of all, I would ask @jamesmartin for his advice.
Have you tested the servo yourself, or have you just taken their word for it?
Do you know how to test it?
How much do they 'quote' to change it?

Haven't had a chance to test myself and also don't know how to. I mean compared to another 110 of the same year I drove the brakes are far worse on mine. The other thing is the garage said I should just do it myself, I have done a fair amount to the car myself and they have no gain by telling me that it's not working properly and that I should work out which type it is and do it.
 
OK so you have discs on the front and drums on the rear?
If you have, then you will have a single leading shoe on each side, with a snail adjuster for each shoe.
Adjust each one evenly until it binds, and then back off a couple of clicks.
Then, with the engine running, pump the pedal hard a few times to centralise the systems.
To test the servo, with the engine stopped, pump the pedal and it should get harder, and you should hear a hiss as the air replaces the vacuum.
Keeping your foot on the pedal, start the engine, and you should feel the pedal drop.
If the last two things happen, there is not a lot wreong woth the servo, and having adjusted the shoes on the drums, you migght not need to do anything else.
My philosophy is to start with the cheapest and simplest, and work on from there.
