Can any body help putting 120y discs on the 1000 cant find a brake booster Iv been told the wagon's the go they are smaller so what els can I do. Does it need to run a booster, I thought discs with out a booster made a harder peddle any one can tell me a alternative

Hi Mate,

Nope you will not need a booster. I dont have one on my race car. The car is light enough not to need it at all. It gives alot better feel without one. In terms of the 120y setup, it has been done on my rusty old parts car, so if you want I could take some photos of it for you. Or if you are keen dattoman_1000 makes a kit especially for the 1000's that bolts on (i think?).

Cheers, Ian

Yep dattoman_1000's kit bolts up. Ive got it on my 1000.

How does the 120Y setup work? I always cringe when i see those calipers!

And no you dont need a booster. The pedal is a little harder i spose, but nothing noticable. Boosters just aid the aplication of the brake pedal so in such a small car it isnt really nessisary!

yea thanks for that I have the set up to adapt it to the front axles but what parts I need to set up a master cylinder I dont khow what I need. I have a duel master cylinder I think off a 120 y but they have a couple of different bore sizes I dont know which one I need can you help

With Dattoman_1000's setup we use a 1000 coupe tandem master.

That is with KC laser front calipers and 1200 rear wheel cyl to keep the balance correct.

11/16th will do the job with most single piston brake setups

Its actually a Sunny master cylinder Chris
13/16

I've used 11/16 3/4 and 13/16 on my own cars
I don't mind any of them
The 13/16 in the current wagon feels fine
Not too hard not too soft
Same as yours too

Squah has a 7/8 on his ute as the previous owner wanted it that way

I have enough hubs left for 3 more kits assuming rueby_tuesday wants this other one

7/8th is rather hard though....thats when you consider putting a booster in (in my case anyway)
