OK Last night my friend and I converted his s13 240sx to 5lug from an r32 skyline.

The rear subframe bolted in fine.

But up front we encountered some problems.
As most know the brake lines will not work. We used lines off an 84(?) Celica parts car that had good brakes when parked (2-3 mos ago)

The front consists of s14 S/E Spindles and R-32 4 piston caliper brakes and rotor.

We put them on, bled them, and the fronts worked sparatically.
The backs worked fine.

Then we took it for a test drive and found out the backs were the only ones working. Took it back, and Bled it again. Still no improvement on the drive around the yard.

We switched out the master cylinder at this point for the M/C out of the Skyline. (with 3 lines, 1 for back, one for Left Front and one for Right front.) Bled them again, same problem.
When you press the brakes, they dont have anywhere near as much pressure/resistance as they should.

If someone could please give us any suggestions as this car needs to be on the road BAD. Thank you!

 

could either be a vacuum leak somewhere tryin using the brake lines for the 300zx brakes.. just my 2cent

 

i believe the 240sx lines can be adapted the the calipers, but you need some copper washer is something, a guy did it with the 240sx stock lines on freshalloy green car s13 coupe
