i have just finished the second caliper, it was just as filthy as the first, Now i have the brakes all bled and done, i noticed that when i turn the wheel, the (brand new)pads
are still rubbing on the disk - is this because they havent been... um ...seated?(is that the word?).
Also, are the front drums the same as the rear drums on a ute? Im assuming not.
thanks, Linc

it is normal for pads to rub against the rotor, as they are always in contact. unlike drum brakes, disk brakes do not have return springs to pull the friction material away.
also because of the way that they are designed, disk brakes are self adjusting. this is why the level of fluid in the mastercylinder goes down as the pads wear.

Linc, the utes came out with a disk brake frontend, not drums.

coupes came out with front discs not utes

The earlier model utes were drum braked on the front, the later model 1400 and 1500s got the discs. A long time Datsun rally driver over here built a 1200 ute for rallying as the
homologation for the cars had long run out for international competition. He fitted discs to it and discovered they were considered a homologated Group B mod, so he had to compete in the
same class as the Lancia Delta S4s and MG 6R4s !! His ute was probably the last 1200 to compete in a round of the World Rally Championship. Over the following years it was further
modified and ended up with VG30 twin turbo squeezed under it's bonnet. Sadly it was destroyed in a very high speed crash a couple of years back. I will dig up some photos of it.

Yeah, my ute is an '83,had an A12, and definately had drums on the front - i was just asking, because the drums i replaced had brand new pads on them, and i was wondering whether
i could put them in the back if they were the same size.....
cheers,
Linc

You probably could, but they won't fit. Different unfortunately. I know what you mean, I've bought a couple of cars with new looking front drums, it feels like a waste...I
know what you mean.

Well, there u go. I never knew that at all. I just assumed all utes had disc brakes because of the extra loads it
has to carry.

Stirlingmac, that ute sounds like it did its fair share of traveling. Some pics would be nice for sure.

As far as i knew Discs were an optional extra on all 1200 models, The Drum Dia is the same front to rear, but the wheel cyl
are a different setup.
I had a bushbomb with rear drums on the front.
It seemed to work, but it was only driven on weekends so Im not to sure of the long term affects.

I'll bet that the "caliper question" holds the record for the most replies (Re:'s) in the history of the "Yahoo 1200 Club". It's great how a single question can get everyone going.
In Canada we only got the Coupe & 2dr Sdn. No 4drs, Utes, Gx's or station wagons here-(that's what we call estates here.) All 1200's sold in Canada came with frt. discs.
A note on cleaning calipers, or in fact any brake hydraulic components. (other than shoes & pads of course.) If in doubt, clean the parts in brake fluid. Its usually cheap & available. In
trade-school they always told us to keep all other cleaning fluids away from hydraulic parts of brake system. Wheel cylinders, calipers, & master-cylinders can sometimes absorb solvents or
varsol. This can then contaminate the new brake fluid when you refill the system, & cause seal swelling + sticking pistons etc. When I've done cleaning the parts I rinse them well with
water & then make sure to thoroughly dry them with compressed air & or a clean absorbant rag. Brake fluid is also the best assembly lube for wheel cylinders caliper pistons etc.
Last but not least, don't get brake fluid anywhere you don't want paint removed or any surface damage. Wash your hands thoroughly whenever you've been handling it, & if you spill it quickly
wash the area with lots of water.
Saftey-glasses are also a good idea.
