Swapping FXSJ brakes for FXGT brakes - advice

[corollaboy]

I have an ae101 FXSJ- it has disks on the front and drums on the rear. I have a set of ae101 FXGT brakes that I can put on. I have compared the two front brakes and the discs and callipers from the FXGT are bigger than the FXSJ ones. If I swap the front ones over will I need to upgrade the master cylinder due the different amounts of pressure needed for the bigger brakes or will be ok to just swap the discs and callipers over? I know if I put discs on the back I will need a new master cylinder due to the pressure difference between the drum and disc. Hope this makes sense! Any advice would be good. Cheers

hmmm don't know why you would need a bigger brake master cylinder I am assuming it's the same as an SJ levin AE100 which you will need the whole lot will all bold up. One problem. CERTIFICATION!!!!

According to the Low Volume Website you need to get a low volume cert for changing drum to disk.

Try to get the Brake master cylinder from the fxgt
Also you will need the bias valve from the FXGT (it is a small metal thing near the master cylinder that the pipes go to from the master cylinder and then off to the rear brakes) This is so that the correct pressure goes to the rear brakes as disk brakes are less sensitive so they need more pressure to work correctly.
Also you will need the hand brake cables off the fxgt to fit the rear disk brakes.

Good luck
