S13 Front brakes in AE86 rear

[heshan]

It might be the rear discs being too worn out and using crappy pads.. But whatever it is unfortunately even with a hydro setup it doesn't lock up.

I was looking at getting steel braided lines and new discs and using mintex pads but now I'm thinking given that I have the S13 parts lying around I'd use it in one go. Its cheaper in the long run.

Even to use larger discs I need to use the AJPS adapter plate or make one.. I'm thinking to do both 3 things in one go. Go for large discs, go for larger calipers and go even larger than S13 rear brakes which is whats done normally.
