Overhauling a MC

[stick3]

I thought it did but then wasn't sure as its a weird looking thing above the axle. I should be right then to use the master from the wagon hey? Neither have ABS.
Would the wagon even have a proportioning valve?

there a difference between utes to sedans ,wagons or it wouldn t say in there adds and they all fit abs or non abs all have 3 holes just one is plug for abs

So a wagon one will be no good?

I can't find any that say fit ute. Anyone know what the difference is?

it must be for a ute https://www.ebay.com.au/itm/New-PROTEX-Brake-Master-Cylinder-For-HOLDEN-COMMODORE-VR-2D-Ute-RWD/122275180536?fits=Model:Commodore|Plat_Gen:VR&hash=item1c782b2ff8:g:TqwAAOSws0ldH4MT
this is the only one on ebay the rest are for sedans or wagons does this look like yours as from vs are different

I forgot about the load sensitive adjustable Proportioning valve being above the diff on utes. I remember reading about it here on a thread about various braking systems quite some time back now.

The wagon one will not be suitable as it has the fixed proportioning valve internally within the MC, also ABS fitted vehicles are different to Non ABS fitted vehicles, thus why there are differing listings for each variant. Sadly it's not all that simple.

BTW I've confirmed the above statements from looking in the VR Service Manual Vol 2 which covers the brakes rather comprehensively.

Also ABS was never fitted to any VR ute in either V6 or V8 configuration.

Looks similar but at that price i would try and overhaul mine. Doesn't say if its a V6 or V8, V8 use a 1" bore i believe and would be too hard unless i use a V8 booster.

Might have to get the mech to check mine and hope its not leaking.

they also can supply recondition units just send them a message its in the page just scroll down half way

 

[losh1971]

Yeah i might have to go reco if mine is leaking. I don't it is leaking as the pedal is hard as. Only issue is the threads can bind up when you remove the lines, which leaves metal from the MC on the flare nuts.

If i need a replacement I'd rather not have to send mine away. Already been off the road three weeks and I'm thinking it will be another two weeks at least before the mech gets the engine back in.
