    Hi All

    When I inquired with holden about what Brake master cylinder is fitted to my car they were not sure. They could say the difference between brembo package bmc and non brembo bmc...but not which one is fitted to my car with heavy duty brakes.

    This was their answer:

    "We have been advised by a Holden Subject Matter Expert, the master cylinder is a different diameter. It is 27mm for Brembo and 25.4mm for others."

    I was looking at my BMC tonight and noticed it has number 27 stamped on it.
    The picture shows where the number is stamped. I am not sure if this is a coincidence or it is in fact larger BMC due to Police spec brakes.

    I would really appreciate if you could look at your car and see what number you have and let me know. Would be good to know what redline commodores have stamped as well as non redline models so I can compare.

    Cheers

    @Ron Burgundy I think I remember reading somewhere that the police spec option got the larger master cylinder (the same as the redlines) along with bigger rotors thickness and diameter and a better brake pads. I’ll try and get a pic of my master cylinder tomorrow (MY15 SSV)

    Yes they advertised is as larger bore BMC but when I needed this confirmed by holden in writting they could not confirm 100% this was the case.
    Yeah..my car has 345mm rotors and large single piston caliper in the front.

    This may come as shock to some (NOT) but I was never a fan of how these brakes look on my car. Always wanted to upgrade to Brembo. This is now back on the cards so need tonwork out if BMC needs to be replaced... ;)

    I am just not sure if I do the front only or the rear as well...

    If budget allows, I'd go front and rear Brembo's.

    No great rush, so most likely front and rear.

    I'm doing the same thing.
    I have the fronts already but the rears are getting hard to source at a reasonable price. They are around the same price as the fronts. Even imported via amazon they are close to $1000 shipped.
    I'm going to put the bigger bore master on as well.
    And leave the standard booster which I think is the same.

    So yours did not come standard with Brembos?

    Bigger BMC is not expensive. New from holden about $160. See pic for part no.

    The mistress (SSV) has 25 and I fitted the 6/4 pots.
    Thank you for the part number @Ron Burgundy that is my next purchase.

    just out of curiosity is the HSV GTS bmc the same as the redline one?
    If not dose anyone have that part number at all??

    No , I have the same as Mattricho , ive been meaning to change it . I was thinking of getting the Cadilac BMC , i'd be interested to know if this would fit in the VF , if not the Redline one will do.

    EDIT: They damaged my car a couple weeks ago during a service (more fool me), wonder if I could wrangle a deal

    Do both and be sure to go 6/4 pot as you will need to get a cert either way . You wont regret it

    Exactly what @kleanphil said go the 6/4 pots.
    The seller on eBay I got mine from has always got them in stock and in pretty much any colour you could want red, yellow, black, silver but all at a price the silver ones are the cheapest and I think look really good behind a darker rim and I think the red ones are the dearest.

    I don't need anything more in terms of braking performance...Just wanted better looking callipers. Redline spec. will do.
