Hey guys I recently swaped to manual brakes on my cutlass. I made my own block off plate and used a S-10 master cylinder. The brakes just don't feel that strong to me. I have been reading people are using larger wheel cylinders in the rear from an S-10 but my dad checked today and the threads on my car are M10X1.25 and the wheel cylinders from an S-10 are listed as 3/8-24. Can anyone help me out here.
