I want to replace my 1980 CF-250 (front disk brake, rear drum) brake master and booster without having to do modifications. I read I might be able to use HZ, Torana or Ford XY. Can anyone confirm this or does anyone have other suggestions that will work? I would prefer to buy new rather than second hand and have seen quite a few muscle cars have new parts any of them work?
Cheers

hi brad, we recently discussed this, so i can direct you to the thread
http://www.buga.com.au/index.php?option=com_smf&Itemid=2&topic=1244.msg11587#msg11587 (http://www.buga.com.au/index.php?option=com_smf&Itemid=2&topic=1244.msg11587#msg11587)
take note of the post by 'ethyl', as he has pointed out several holden car models that are the same booster/ master, that will work for you
i have used the lh torana and its great
little bit of filing and a couple of new pipes, no worries
mind you, i'd like to hear from someone who has tried the ford xy
-
someone posted ages ago that they had their master cylinder bored out to 1inch (from 3/4¨).
that would require the least mods, would´t it?
-
that sounds interesting, i wonder what they did for the piston and seals needing to be larger
now this got me thinkin' what have people done when they put disks on the front, can you still use the master that comes standard on the beddy?
-
Thanks Kav yea I had seen that post before, just could not seem to find it again when I was looking. That link you posted (http://www.buga.bedfordcf.com/funk/thread.php?id=291 (http://www.buga.bedfordcf.com/funk/thread.php?id=291)) does not seem to be working? Did you have any trouble fitting it under the hood?

Hey Worzel I looked into getting the old master bored out like the post said but when I was asking about it no one around me seemed to do it themselves all sent it off to get done elsewhere and looked like it would cost as much or more than replacing it.
Thanks though
-
sd1 rover are identical to bedford except the ports are on opposite sides and the bore is 15/16, just about 1'', it bolts straight on to the bedford booster, just been down to the garage to look for it so i could post a pic comparing the two but couldn't find it, will have another look tomorrow :)
-
Thanks hunterbynature what about a booster do you know if they are interchangable. I appreciate the effort you have made to look for me.
-
you just use the bedford booster, or if you want a bigger booster go with LJ torana booster and master cylinder, the booster fits to existing holes in firewall, you just have to file them out a bit bigger then booster will fit on, there is a bit of clearance prob with bonnet hitting cap on reservoir, i think its just the clip that holds it on, easy fix got sum pics somwere if you need them cheers stevo

yup, might cost as much, but stainless sleeve will last longer and nothing else (linkages, firewall, and tubes) has to be changed.
I´m not saying it´s a good idea, just that it´s worth a look.
that rover sounds easier
-
Yea Stevo pictures would be great help. So will I need a double diaphram for a V8. Why does it make a difference what engine size I have? Does the LJ Torana booster come in double diaphram?
Thanks mate.
-
hey brad, when i put my torana booster in, i had to shorten the shaft that pins on to the pedal, drill a new hole for that pin aswell. i took my clip off the top of the resevoir and clamped it down with two hose clamps so the bonnet would shut, it takes screwdriver or 8mm or 5/16 spanner to check the brake fluid level .
if my beddy master wasnt ruined beyond repair ,i would've got it fixed
on one hand its kinda simple to do torana, just fiddly, but if its just seals or even re-sleaving you need, i'd go with that
-
hey kav mine jst bolted straight on to my pedal for some reason, the travel seams to be the same, how much did you shorten it?
-
hey hunter, i had to take about an inch off
i got the torana advice off the old buga forum but no-one mentioned having to shorten anything, so i was a bit nervous and confused when i did it as everyone said it'll go straight in
mine's a swb, is yours a lwb, are the cabs the same?
-
hey mate , mines a lwb, pretty sure the cabs the same, got 2 swb aswell, i think i used the bedford pushrod as aposed to the torana pushrod, or was it the other way around, cant remember, will check it out tommorrow, wont be able to sleep tonite now, it'll be bug-in me all nite ;D
-
Does the LJ Torana booster come in double diaphram?
Thanks mate.
there was a double diaphram but only in the XU1 so are scarce and expensive, $250 to $300
the LH/LX had one as well in the V8s and would be more avaliable
if using LC/LJ booster be careful mixing master cylinders as the push rod between the booster and master is a different length, could be a concern with beddy master
-
when i did my 4 wheel disc conversion i used an lj booster with lh master, the booster had an adjustable push rod which was just a matter of trial and error when adjusting to get a good brake pedal. got an issue with the master hitting the bonnet tho.
xb master with lj booster is the way to go

hey guys been searching a bit for brake boosters and masters found some good new ones but was looking at 8" dual Diaphragm booster and master but found out they are all too long for the beddy. Will the braking work just as good if I were to use say an 9" or 11" single diaphragm booster for my V8?
