Girlock brakes??

are the brakes on the back of a US mopar
Girlock brakes?

i believe Girlock stands for Girling and Lockheed

now is this a classic case of appropration of a name to cover all types of drum brake

like Hoover is used for any kind of vaccum cleaner

or Hotchkiss live rear axle relates to diff n cart springs

the reason i asked is because

my little diff in the back of my aussie valiant uses what the aussies say are Girlock brakes.

the diff is not US sourced and is australia-centric in everything

they look like a clone of the US sourced brakes on the 7 and a bit inch diff used in slant 6 and small v8 US cars. Thats based on fuzzy internet pictures and what i can work out from my aussie manuals

i.e if i wanted to get some new rear brakes onto a diff i have i could scrounge round getting second hand parts in Oz new cylinders and shoes and pay approx the same as buying a kit from the US or a US importer with the whole shooting match new.

I have no access to both type to cross reference
Anyone out there owned an aussie car with a Borgwarner diff and fitted small US brakes in place of the standard aussie ones. i don't belive aussie cars used the same size of drums as B and C bodies but could well have had the same as some A bodies due to the A body heritage.

My XY Fairmont has a Borg Warner diff etc . I sourced wheel cyls from Australia .

You're welcome to look at the brake assemblies etc if it helps as a reference.

Sorry , but have no interchange information regarding rear brakes and US parts .

Pete or Steve at USAutomotive have put together a list of interchangeable Aussie parts like that.

Late to this, Dave, as I have given up on this forum, but, as Matt pointed out, and our emails back and forth about the guy with the XA and the busted axle, any early Falcon that wasn't 351 powered used the BW axle, and I suspect, but my manuals don't explicityly say it, that they used Girlock drums as well.

I know XA and XB's used a combination of either Girlock or PBR front disk calipers, and PBR rear calipers if they had disks out back.

Might be useful, Dave.

many thanks

looks to be exactly the same

even down to the choice of 2 spider or 4 spider gear LSD centres

those brakes look very familiar as well

MMmmm

i'm guessing the only real difference will be the backplate 4 bolt spacing
as this changed on the valiant and was again different for disk which Vals never had.

easy overcome

wonder if i should fit disks
