78 280Z rear brakes on a 71 240Z

[Dave]

I have spent the last 2 days searching for any reference to

swapping the 77-8 280Z rear brakes for what is stock on my

71 240Z. My motive is 69-76 wheel cylinders are $150-$200

a pair, 77-78 are $12-$25 a pair and are stocked everywhere.

 

I have the complete backing plates from a 77-8 Z and see no

reason why they will not work. I realize I need to pull the axles

to swap this stuff over. Am I missing something since I can't

find anything about this being done before on the 240Z?

 

I have swapped the front for 300ZX rotors and 280ZX calipers

and I used the 280ZX master cylinder and am still using the stock

drums on the rear and every thing works. the wheels are 6 spoke

280ZX. The last hurdle is to fix a leaking stock rear wheel cylinder.

The Nissan cylinders are a little pricey, but I think it was worth it. Mine were $76 each, genuine Nissan, and ordered from a Carquest auto parts store. I have a '72, so it is the same part number.

I just checked the Autozone website, and they listed off brand ones for $23 a piece. Maybe some more searching might prove useful.

I ran the 280z rear drums on my 240 for about 5 years. They seem to stay in adjustment longer. I had no problems at all with the installation.

they bolt right on, you will need the brake hardline that goes form the slage tot he rubber line, on the 240 the slave it att he top of the assy and the 280 it's at the bottom, kinda tired I might have taht reversed but you'll see when you look at them, only the 77-78 got the dual piston setup, thall the earlier cars got the single setup

Ive got a 280z rear drum assembly Ill sell. The drums were turned and the shoes are newer. Ill include all the little pieces that I pulled off for rear disk conversion. (shoes, piston/cylinder, brake line, springs) All the brakes were redone a few years ago and its just sat.
