    Default 404 drum brakes

    I have a Melbourne built '68 404 sedan with four wheel unassisted drums. I want to replace my rear shoes and have struck a conundrum. The 'brake books' one finds in auto stores say that the brake drums/shoes changed in 1965 and have different brake cyliders,shoes,drums. As we all know, the Aussie made 404s didn't always update at the same time as the French. Now I am aware of the Hydrovac (1965) and Mastervac (1969) mods overseas but of course my '68 has no assistance or booster. Ok, my question is; should I treat my car as a pre 65 model for brake disposables, or should I purchase the shoes that are encompassed within the chassis number parameters in 'the books'?

    Of course it may provide some logistical problems, but could you not use your existing shoes as templates?

    Otherwise, accurate measurements of all critical dimensions might assist.

    It would seem likely that your disposables would be after '65. Order from the book, if they dont fit, exchange them.

    Would be best to take your shoes to a brake specialist and get them to bond new linings to them or as Edge says they can measure and order in exchange shoes.
    Good luck !

    ANother thought...it's very worthwhile to get your new brake shoes radius ground to match your drums. There are lots of 404's i've seen with poorly contacting rear linings, because they weren't raduised to match the drums..and as the rears take a small bart of the braking load they take a long time to wear in.

    Err, thanks for the suggestion. On a more general level, did 404 brakes in Oz change at all before the advent of boosting? You see, I have a set of (early) rebonded brake shoes (E1280) to put in...

    Yep, PCOATES505, that's the best thing to do. get out the brakes spring pliers and remove the old ones...... from memory I don't think the sedan rear brakes had too many changes other than wheel cylinder bore reduction...to account for boosted later types. The shoes looked remarkably consistent.

    Not sure about the brake shoe size. Needed to replace brake cylinders in my 404 at one stage. Dealer told me that my vehicle was"French Motor Show Model" whatever that was and the only available cylinders took a smaller diameter pipe and "nut". I had to make new brake hydraulic lines for the car.

    The big rear brakes were fitted from mid 1965.
    All had 1inch cylinders until the disc brake models.
    The earlier cars had 1/4 inch pipes, the later 3/16, this explains the different cylinders.
    The 1968 rear brakes are the same as the disc brake cars except for the cylinders.
