    Hi

    I recently took my 2000 E46 318 coupe to kwik fit for a brake check as my brake light switched on.

    (i expected it to be just new pads required)

    They told me that the main cyclinder needs replacing and all the fluid has leaked out causing damage. they suggested that all pads/discs (front/back) needed replacing as well as the main cyclinder itself..

    it would have cost about £800 which i refused to pay and drove the car home...

    is it common that all pads/discs need replacing if the fluid leaks completely??

    pls advise??

    Pads and discs would not need to be replaced as a direct result of the cylinder failing. That said, I've personally never heard of an E46 cylinder failing in that way at all! Maybe the fluid was low because the brakes are worn..

    The moral of the story? Never, ever go to kwikfit for anything, ever! Unless you WANT to get ripped off!?

    1st mistake Kwik fit for brakes!!

    E46's can flip there seals in the master cylinder but this problem normally happens when they are being bled.

    If the fluid HAD leaked out surely there would be no pedal pressure and you would have very little brakes anyway.

    I refused to have work carried out by kwikfit.. but they topped up the brake fluid for me..

    Im gonna take it to my indi to have a look when im back from hols..

    Ive not driven the car since i brought it home but the brakes still work (a little less pressure than before the whole issue)

    how much would i be looking at to just change the main cylinder?

    You have to make sure it is the cylinder first. Could also be corroded pipework that may be leaking fluid.

    Just came back from holiday. After leaving the car unused for over a week, theres no signs of a leak (garage floor dry - no signs of fluid) and the cyclinder looks completely full still. I took it for a little run and the brakes feel a little better but still gona get it checked out tomorrow
