    Hey guys, so I spent all today getting my brakes changed out. I have the E36 M3 Evo 3.2 servo, master cylinder and fluid bottle, E46 2001 330 calipers, new Brembo Max discs and new pads, 5.1 fluid.

    The problem I am having now is the brake pedal goes near enough to the floor before there is any pressure in the pedal/brakes. The system was bled through, 1 wheel at a time, checked for leaks, all clear. Is there something I've missed?

    Still sounds like the system hasn't been bled properly...Also check The End's post on brake fluid....you are probably better off with DOT4 the 5.1......

    That doesn't sound good at all, and it still sounds like it needs to be bled properly.

    IMHO I would bleed it again just to be sure.

    I thought you had to renew the pipes if you swapped to 5.1 ?

    Did you put some brake fluid in the master cylinder before fitting it? Sounds like you'll need to use a vacuum bleeder and around 2 litres of fluid to properly get the air out

    No, we just did the foot pumping the pedal method. I had the brakes bled through when I first got the car at a garage, they DID use pressure bleeding.

    No, the master cylinder and fluid bottle were both empty while fitting. Fluid was only poured in AFTER fitting os master cylinder, servo, both calipers.

    When I am travelling along, if I pump the brake pedal 4/5 times, it does build up the pressure, but when I put my foot down on the brake pedal after pumping, it still goes to the floor, albeit with some fluid resistance. I'll see about getting it pressure bled then, see if that fixes it. I still have to get the SS hoses fitted yet, they didn't arrive in time for them to be changed with the rest.

    ^^ vacuum bleed it.

    But first make sure you servo is properly working by having the engine off, pumping pedal as hard as it can get and then keep your foot down on it and start the engine. Pedal should go down if servo is working.

    My mate had a mondeo come into the garage with the same problem your having and I was around watching him using the vacuum bleeder. You can see massive air pockets getting sucked out.

    i use 5.1 in my race cars, is it less viscous and coupled with steel lines gives a really firm pedal, also has less tendancy to heat up and thin out. i agree with the other guys, pressure or vacuum bleeding is needed.

    ive got kind of that problem on my 328, the pedal on 1st pump goes nearly to the floor and on second the braking is noticably sharper. the system is fully bled - is the servo for me... was your servo brand new or 2nd hand??
