Looking for a new or rebuilt one for my 74 260z build - seen them on evilbay for around $300 which seems a bit steep... anyone know of a better deal?

 

Or... if there's anything bolt-on (or minimal mods) from another car that achieves similar assistance?

 

OR..... if there is such thing as a booster rebuild kit?  Happy to get my hands dirty to clean it up and paint it, etc, but if the innards are buggered and can't be replaced there's no point (nfi what condition it's in, I vaguely remember it working when I drove the car last in 2007)  No doubt there's something made of rubber in there that will have degraded over the past 42 years and is worth replacing.

I can't remember the cost but mine was reconditioned by an outfit in Sydney (can't remember who either which is not real helpful !!).  They often require blasting and painting as well as all the diaphrams replacing so reco is up around the same price.  $300 seems pretty reasonable to me.

A few brake places in here might be able to help?

I used an R33 gtst brake booster which bolted straight onto my 15/16 MC. should be easy and cheap to find

Hi guys,

I take it the R33 brake booster will has the same stud spacing as the original 260z ones and will bolt straight in place?

Or is there other better ones to fit?

I'm looking at doing the 4 piston hilux front and r31 rear to two of our zeds at the same time and will also upgrade to the 15/16" master cylinders at the same time.

Justin

Only certain r33 bosters fit. I purchased a BM57 r33 booster and the hole centres were off. I just transferred the measurements into the firewall and re drilled them. The BM57 r33 master cylinder is very good aswell as its the largest at 1 1/16" used in the r33 GT-R all that was needed was new lines from the master cylinder to the splitter.

Thanks Chris, I suppose I could also open the booster up and change the mounting studs to suit as well though a bit more stuffing around.

It is very tight up under the foot well in the zed's. Pretty certain I was stuck upside down at some stage!!! ☺

The 280ZX is a bigger unit 9" as opposed to the smaller 260Z from memory but same bolt pattern as 260Z . I bought a second hand one then took it to Penrith brake & clutch who repaired it for $200 , I used a  1" brake unit which all bolts up the same.

Also fitted the Hilux front brakes but not the vented type as I didn't like using the washers you have to use to get them to fit correctly . The rotors I fitted were the drilled & slotted units .

 

                      Regards : Alan .

Lol yes Chris there sure isn't much room under the dash of them at all.

Alan do you have much feel with the 1" master cylinder?

Justin.

From the few times that I've sneeked it around the block , they have good feel , not rock hard & wont put you thru the windscreen .

I'm happy with them , remembering I have a big 280ZX motor in.
