Brake servo’s

I have been looking at brake upgrades and come across potential alternatives to the ‘over priced’ mk2 gti route.

Lacertti (Daewoo/Chevy) - old thread on owners club about being a straight swap then some comments about hard brake pedal which would suggest less assistance possibly????

Vauxhall Zafira -looks like a good candidate but not found any attempts.

What do the wise old owls of this club know.

I am feeling very cautious about spending £100 plus on a second hand, rusty servo or several hundred for a new one when other cars have complete set up available for less that £50.  Feels like we are being taken for a ride.

Thoughts.

I recently went through the same thoughts when rebuilding a caddy however so many hours can be spent thinking about let alone trying to source parts that may or may not work and wasted money if they don't. I purchased a new servo and master cylinder from Mark at ClassicVW after speaking with him for advise, parts arrived and in a few hours it was all done dusted, works a treat. Sometimes money is well spent and I feel that where brakes are concerned although it was a chunk of cash, it was well spent. 

You can use a MK3 servo - but it requires some modification. You need to hack the ball end off the rod, and then cut a thread to fit the clevis end - but they are a lot cheaper. I think I paid £20 for one off ebay.
For MC, it's best to buy new, but as they don't come with the reservoir bottle, you'll then spend a chunk of money trying to buy one of those!
I did a load of digging, and after reading this thread (https://vwgolfmk1.org.uk/forum/index.php?page=topicview&id=running-gear_2%2F8v-16v-mk2-brake-servo), ended up with a T4 master cylinder that I got off ebay, complete with reservoir for not a lot of money. I did have to make a new connector for the fluid level thingy though.
I beleive Seat parts are an option these days, but couldn't find much info on that. I'd stick to VW family as opposed to looking at other marques.

I bought one from a clio, they are cheap, and much newer.  It bolts onto the linkage with the 4 studs and it seems to fit the larger (22mm i think) master cylinder i plan to use. However i have only tried the parts of the car and as its actually 10 inch diameter i am concerned the extra 1/2 inch all round compared to the 16v 9 inch one may cause a fitment issue..
