Disc brake Salisbury conversion on a county. What master cyl and booster

[sclarke]

Guys,
Ages ago i put a 130 Salisbury disc rear end in my county, and only today have i finished it enough to drive it.....

Brakes are POX

What master cylinder and booster have you used when you converted a Drum rear to disc on a county???

Clarkie,

If you have a donor vehicle, use the Defender pedal box, booster and M'cylinder aswell that is the way we do it and it feels like a Defender after that.:)

Cant, long gone.....

So do i need the pedal box as well from a defender???

was thinking about trying a Disco booster and master cylinder as they are 4wdisc
Got a few of them...

Defender Pedal box because the booster mounting pattern from the county is too far removed from the defender booster pattern. I have heard of someone using the dual stage disco booster, BUT I can't confirm if it will fit etc. The Td5 Defender uses the twin diaphragm type booster, but I reckon the brakes on the earlier Defenders are just as good with the single diaphragm type.

If you are going to try a Disco booster and cyl, make sure you use a 1994 (MA facelift) one as it has the single front brake lines like the county.

Sorry I don't have a Defender pedal box etc:( All been used for what you are doing.

I have a 130 rear in my RRC, with the calipers and all and it works fine with my original 4wdisc setup even though the pistons in the rear calipers are slightly bigger diameter.(Very small difference)

Lots of stuffing around, but i'll pull a disco one out and see if i can make it fit. i Have a few..lol

if not... then i'll just cope until i find a defender setup..

Fred Smith put a Defender 130 master cyl/ booster setup in mine, as it has discs in the rear (130 rear end).
I can lock it up at 60kph :eek:.
Must try it a bit faster :twisted:

Mine had 4 wheel discs when I bought it. Previous owner said he did it with a "factory conversion kit". Maybe this is covered in a spare parts book or disc?

That would be using a defender std one... from a MA vin onwards

Going to try a Disco one 1st....
it will fit from what i have measured so far...

Let me know how you go with the booster Clarkie, I haven't had time to really research it / compare for myself. I was concerned mostly about the pedal attachment as they are quite different.

Keep us posted, Clarkie and I'll add it to the Good Oil conversion thread.

Yes a Disco booster with master cylinder will work... and does work

Good thread Clarkie. I know you used a defender rear axle but have heard of drum axle being modified for discs.

Another option used by the army 110s was to weld a plate on the pedal box to enable a bolt up of a PBR booster/MC from a EA Falcon. Not sure about connections.

I put the defender rear in my county years ago, and also had the poor brakes for a while. I ended up changing to vented callipers on the front (defender, not rangie, as they have bigger pistons) And still no difference. So i swapped the booster and master for a defender one also, and re-ran the brake lines for a twin circuit front end, and it stops like a defender now for some reason.

Funny that....

Know why LR went to solid disc on the front of disco's??
Because i complained about the vented filling with mud...lol

Solid are better offroad for that reason only i think... my 20c

you can clean the inside of the vented rotors out of all the Mud ,just a high pressure girnie should do it :D:D
