MSA 4-piston upgrade with SS lines

[chickenwafer]

thanks guys. I will deff be looking for some new brake calipers, knowing that I could home-build a system for around $300 or less. I wonder if any other 4-piston Japanese calpers might work? I'm sure there has to be more. At a junkyard the other day I found a wrecked '98 Corvette. They have at least 4-piston calipers and at least 12.5 inch or so front rotors. Maybe I could adapt the front and rear brake systems to the Z.

P.S. Sorry Mark, I guess I kind of raped your thread . Did you ever get the stainless steel brake lines to work properly??

the toyota calipers, when comparing them to the Datsun calipers, are basically exactly the same...same manufacturer's design just one is 4 piston and one is 2 piston.

Ok, big question....does the M/C have to be upgraded to the 280zx M/C? I've heard the 4 piston calipers use so much more fluid that the smallish 240z stock brake m/c can't handle it...well it handles it, just not very well.

Any thoughts/input on this are very welcome....

I've read the same thing in many places, but my experience just doesn't match it. I've got the stock M/C and my pedal travel isn't more than before the swap, or if it is, I can't tell the difference. Of course, I also switched to performance pads and SS lines at the same time, so perhaps those improvements offset the larger volume that the new calipers are supposed to require.

FWIW, when I'm braking hard the pedal height matches that of the accelerator pedal for easy heel and toe down shifting. I believe the heights can be adjusted, but my point is that I didn't have to make any changes to them after the conversion.

I can't help but wonder if those claiming the M/C needs to be swapped are "bench racing" rather than speaking from experience.

The size of EACH of the pistons in the 4 pot caliper is smaller than EACH of the pistons in the 2 pot caliper.

While the 4 pot caliper (as a whole) may use a bit more (volume of) fluid than a 2 pot caliper, I don't believe that a larger M/C is required for safe operation.

I don't mean to sidetrack this thread but, what is a banjo fitting? :nervous:

Kind of a 90 degree swivel fitting.

Thanks.

They should've named them "silent banjo fittings" - no strings!!!

I have tried direct hook up from MSA, but the connections to the caliper did not seal well and so it would leak bad. I don't recommend there setup. I have a picture in my gallery.

chicken wafer--

You say under $300....I just said the calipers are $70 for 2, spin the rotors is like $30 at the most...then pads...that is like under $150 actually.

good to know about the m/c cause I just bought one....beandip, you want to interject here?
