    Default Brake Fluid performance vs cost, Mazda interval maintenance

    You know this is the best time with black friday sales and xmas sales , new years sales, to look at buying discounted upgrades or just parts for regular maintenance in 2021.

    Many do not think about brake fluid, I know many on TM3 say dont touch the brake fluid unless necessary.
    Long story short Mazda manual says to replace every 24 months / 40,000 kms... whichever comes first.
    You will need 500 ml for those DIY brake line bleeders.

    If you considering upgrading your brakes, are a spirited driver, do autocross slaloms, track your car or time attack.

    Here is quick snap shot of some research i did when comparing Liqui Moly Racing Brake Fluid (not many places have it ...
    Liqui moly doing a product redesign..but GermanParts.ca should have it when available...)

    Brand dry boil / wet boil price size

    Motul 600 312 C 205 C $25 500 ml ~ i've seen it as low as $18
    Motul 660 325 C 204 C $40 500 ml ~ seen as low as $35
    EBC B307 310 C 204 C $40 1000 ml
    Castro SRF 310 C 270 C $120 1000 ml ~ the holy grail of brake fluids to compare against but i really dont know why
    Endless RF650 323 C 218 C $60 500ml ~ this one presently being used by F1 Petronas and BMW GT series , WRC and Hot and Cold rally racing others.
    Endless S-Four 323 C 218 C $ ~ looking into it , less cost than RF650 where S-Four designed for street / spirited /light track.
    Liqui Moly Race 320 C 200 C $14 250 ml
    Liqui Moly 5.1 260 C 185 C $7 250 ml

    here is link to endless (Swedish company with most if not all products , pads, rotors, caliper made in Japan)
    http://endlessusa.com/

    Im on Liqui Moly 5.1 for this year and a half. I have tested this one on OEM sized calipers with upgraded pads and like the firm pedal feel.
    Upgraded my front to 330mm rotors / 4 piston calipers and kept oem rear and wow what a difference.
    Did 2 really long lapping sessions with high speed late braking ... just last week at cayuga ...
    Over and hour , 52 laps non stop and no issues at all with the liqui moly 5.1 fluid. No fade, same pedal feel and pressure.
    Changing and bleeding fluid when the summer tire come back on.

    Thanks for this list! Very comprehensive I'll definitely refer to this if my 3 ever becomes my track toy.

    "I know many on TM3 say dont touch the brake fluid unless necessary." This triggers me so much, brake fluid absorbs moisture from the air over time and loses effectiveness. DD's definitely should follow the 2 year rule.

    Liqui Moly 5.1 260 C 185 C $7 250 ml
    Is not considered a race brake fluid ...
    Motul also has a 5.1. If it comes on sale buy it.
    They are all packed with nitrogen for longer shelf life unopened.
