Ok, got in my car last night and the brakes are straight to the floor with no resistance at all.

Had a look and there's a pipe with a tiny hole spraying an looks like the o ring between the servo and master cylinder is a bit leaky. Are fixing these gonna sort this, or doin need a new servo/master cylinder?

Before anyone asks its full of brake fluid and the hole doesn't leak, just gives a fine mist when pumping the brakes.

Thanks

ANY loss of brake fluid needs to be sorted before the car is driven again.

Not only are you losing brake fluid through this 'tiny' hole, but you are also drawing air into the braking system.

The 'tiny hole' may not be your only problem though. If there is fluid loss between the servo and the master cylinder, this is definitely NOT down to any 'O' ring (I can't even remember seeing an 'O' ring in there) What will be happening, is that the M/C seals have failed and that is why there is fluid leaking from the joint.

The only remedy for your problems is to replace the leaking pipe (checking the rest of the plumbing before you re-fill with brake fluid); fit a new master cylinder (rather than repair the old one) and bleed the brakes.

The reason that there was no resistance at all when you pressed the brake pedal, is most probably due to the master cylinder piston not returning to the 'off' (out) position.

Regards.
