Help with rear disks


Boomguy

Recommended Posts

Time to sort out my rear brakes that came on my car when I bought her awhile ago. Looking at all the pics posted on the site and I think the calipers are Maxima but the disk which is 280mm doesn't seem to match anything listed on sites I have visited. The bracket is home made and I would like to replace it for a milled one. The brake lines are another story... all this done by the previous owner.

Double check your measurement. A common rear rotor for these kits is a 1985 300ZX USA spec rear rotor. Raybestos 9300R ( I have two sitting in front of me right now ) .  But these are 290mm ( 11.4" ). Canadian spec rotors are 10.15" . The Raybestos  are a a whole $18.48 USD  each from Rock Auto. I got these for my conversion. You don't need drilled rotors. In fact, they are bad for Track days ( They crack )

Those look like home made brackets. You can get CNC billet machined brackets for the 300ZX 290 mm rotors from Z Car depot for only $69.95 USD a pair. Awesome deal!! These are made for the Maxima calipers.

Bought the  rear caliper SS braided hoses from Silver Mine Motors for $75.00 USD. They sell all of their Big Brake Kit parts separately, which is nice.

Edit: The rear SS hoses are really well made. All custom made and no additional adapters required. DOT approved. You just fill out the comments section, telling them what calipers you're using and front or rear. Rears came pre-assembled with banjo fittings on the caliper end and the correct Metric adapter that attaches to the factory bracket on the strut. The factory hardline screws right on. New Banjo bolts and washers are included. Best deal I could find.

Right again Chickenman!  Rotors are 290mm upon closer inspection and explains why I couldn't find a replacement up here. Thankyou again for introducing me to Georges, great guy and did an outstanding job on my Trans!  He even gave me an actual input shaft that he milled off to use as an alignment tool for installing the clutch! Worked perfect for the exedy and tilton. I have now lent it to a friend for his track car that he races at Mission Raceway. 

I had seen those brackets online and thought they looked great.  Wanted to make sure I had the correct calipers for them. Hopefully I can find rebuild kits for them, these would be the 81-84 Maxima caliper or the later 85-87?

Glad to help. Georges is a great guy. I've known him for years, decades actually.  Met him at WestWood way back in the late 70's. Do you know Andy Paerson from Specilaty Engineering? Another great guy and Datsun expert.

We'll have to get together and cruise out to Mission sometime. Are you a member of the BC Z Car Registry? It's been inactive for a number of years but has been revived . I also do cruises with the local 510 club. Huge Datsun knowledge base out here. A lot of the local Z car guys frequent http://www.the510realm.com/
