Ok since i'm going to pull my diff apart for the second time in 3 months. I decided that it was time to put the Disk's brakes in the back of my 200B. Now i have a whole donor series 3 bluebird. But it's a wagon, so it's leaf sprung. So i have 2 question's.

First is what do i do about my master cyl. My 200 is a late model nov 79. and has a girlock master. Can i keep this, or do i put the bluebird matser in.

Second. Because the car has leaf's i am swaping over the axle's. Now there is'ent any braket's on my diff to change the brake line's from hard to soft. So can i just cut these of the bb diff and weld them on my 200B.
Cheers Dat810

1. A rear drum M/C has a small rubber valve in the rear circuit to apply Residual Pressure to the rear hydraulics.
It's called a Residual Pressure Valve .
You have to remove that from the hard line connection to prevent the rear disc pads from dragging. So you have a choice.
You can modify the existing M/C for rear discs OR you can swap the BB M/C into the 810.
If the hard line connections are physically similar and the M/C bores are the same, then my advice would be to swap the M/C.

2. I gather you are using the BB axles, backing plates, rotors, park brake shoes and caliper mounts etc. but not the diff housing? Whatever works for you here, but mounting tabs for brake lines would be the least of your problems I'm thinking.

Thanks nissanman, The 910 master cyl is a fair bit differant. So i'm going to look at taking out the Residual Pressure Valve from my 810 master.
Also i think that i wasent very clear with the second question. I have a h190 diff in my 200B, but with drum's. And with the disk brakes, the mounting braket's for the caliper's and everything else are bolted to the axle. So i thought that i could just slide the drum axle out, and slide the disk axle in. Just the brake lines i thought would be the problem. Which i have.
Cheers Dat810

do you have the aussie pbr master i was told by anthony at grandautos it was fine to run my trx disc rear and i never had issues but itf you have the jap master with two tubes that valve needs to be taken out

Sorry about hi-jacking this thread but i thought it might be a good place to ask this. dat810 says his donor car for the rear disks is an S3 bluey ???? my son's 85 S3 bluey has drums on the back,

i thought only the TRX came with discs on the back or am i wrong and the S3 wagon also came with rear discs

IF IT'S FOOKED FIX IT, IF IT AIN'T MAKE IT FASTER

Cheers doug .My car is an ozzy spec so yer it has pbr master. i though you still had your standard master. Any thought's on putting the axles into a drum diff.

LUVA64-A few differant bluey's came with disk's as it was an option. My donor car is an GXE Ultra, So it allso has clear indacators, Elec mirror's, Elec temp volt's fuel gauges, Funny wing thing's on the back etc etc.

well that explains it then because his S3 bluey is only a GXE

Your best bet is to get try to get a bluey TRX diff. Decent disks brakes as std and it fits straight in.

All you have to do is lengthen or shorten (i cant remember its been about 6 years since i did this) the tailshaft.

I thought the 200B rear axle was the same as the Bluebird, right down to the mounts? Unless you're talking about a H190, then that might be different, I thought it was all the same though.

Anyway, Series 1 and 2 had the H165 in all models, the same as the 200B. The S3 models all had the H190 but only the GXE Ultra and TRX had the rear discs.

Series 1 LX had the discs as well, not too sure which S2 models they came on aside from the TRX.

yes i was talking about the H190. It mounts up fine but the the yoke is differant and the snout is longer.

I would do that, But i allready have a h190 and disk brakes. But there no together. And My H190 is drum. So sould i just buy a whole new diff?
That's right. So you grab the tail shaft that come on the H190 models. Use a 1 piece blueblird tailshaft or a 120Y auto shaft. With the series 3 bluebird diff end on to the tailshaft.

Id just buy a whole new one.. saves the bullshit.

I actually have my old tailshaft still for the 200B > H190 conversion.

So it isent as easy job cutting the brake line tab's of the leaf diff, and welding them on my diff. Or it just wont work?

I asked this question to Dan with a Plan a while back, and he sent me this link. Hope it helps
