Does anyone have a 280ZX front caliper with the mounting bracket they can weigh?

Reason for the question is two fold; my car has 280ZX struts but the calipers have been milled to fit inside 13" wheels. I want to know much weight everything ways before milling. The amount is likely negligible but I still want to know. Note to weigh them properly they need to be off the car.

I'm also looking at mounting Cressida calipers (7lbs with bracket) so I'm trying to calculate the weight savings. I believe it may be as much as 5lbs. At $23 per caliper fully loaded from rockauto it would be a pretty cheap way of cutting 10lbs of unsprung weight.

Caliper with or without brake pads?

 

I've got an old caliper, caliper bracket sitting around. Let me dig it out and will weigh it when I go back to work on Tues.

Tom,

I have strut assemblies laying around somewhere and will take a look also.

I weighed a 280ZX front caliper from my pile of parts and got an approx. weight of 11 1/4 pounds with pads and a cut-off stub of brake hose but without any bracket. I'm kind of hazy on what sort of a bracket those have but I must have used it on my 510 when I swapped the ZX struts on. That weight gives you a starting point although I hope someone else posts weights so I know my kitchen scale is more or less accurate.

 

If the Cressida calipers and brackets are that much lighter it may well be worth going with them.

OK to clarify when I say bracket I mean the part that the slider pins ride in.

The 11.25lbs is what I was expecting. I weighed the Cressida caliper on a crappy bathroom scale as well and as noted it came in at 7lbs. So that's 4 per side / 8.5lbs of unsprung weight.

That part may be called the 'yoke'. It is on the 280x/810/620 style. The 280zx are abbreviated but do the same thing.

Mike , it being called a Yoke makes kind of makes sense; caliper rides on a slider pins like a pair of Oxen in a yoke. Albeit a single piston caliper.

Finally took mine off the strut and weighed in at 10.1 or 10.0 on a bathroom scale.  Weighed caliper and bracket (basically everything that attaches to the strut), with a cut off stub of brake line and NO brake pads....cuz they were wafer thin.

 

 

 

Probably why that car was in the junk yard.

 

 

Yeah, I am late to the party.

I'm thinking of all the Cressida calipers that I replaced with either Z32, or GT-R calipers, and threw the Toyota iron in the scrap pile.

 

As they say, one man's trash is another's treasure....


"All of a sudden it started making noise, then started losing power. I limped the car home and tried to get it up the driveway, the engine just died."

 

Why do people do this?

A $100 tow bill is never as much as the extra damage you cause by trying to "limp the car home".

 

Don't be that person !

Because the 1200 is running 185/60-13s and 1796lbs with me in it, I don't need 4 piston calipers. Wilwoods are normally the obvious choice but in my case there's no need for more powerful calipers.

While the Cressida calipers are cast iron boat anchors they are on 1-2lbs more than the Wilwoods plus I wouldn't have to fabricate an adapter. The final bonus Is cost; $60-$70 total versus $350 for the Wilwoods. Note I like Wilwoods all of my single seat race cars have had them, including my current Formula 500.
