just been driving and the brakes lost their pressure. the car still brakes but only when my foot is right on the floor. i checked the master cylinder and there was only liquid measuring 5ml up the side so only a few tbsp left all up.(naughty naughty, not checked)so i topped up to halfway and pumped brakes a few times but its too late, checked for leaks and cant find any.so question is do i just need to bleed again oris there something more serious wrong! please help, dont wanna go to the effort of bleeding if its something i get a mechanic to do

Make/model/year, have you checked the hoses under pressure, are the pads/shoes worn, is there brake fluid running down the firewall behind the booster, inside on firewall.

What you did is not bleeding - it's called 'topping up and praying'.
You'll need to start by bleeding the master cylinder, then each brake line. Which seems beyond you. So off to the mechanics you go.

I would be bleeding the system, possibly the pads are very low also. But yeah, depends really on system. Bleed them and see what happens.

well, if theres no leaks, you should be able to pump it up once you fill it up, if not, theres a leak. either way, probably will need to be bled anyways, so you might as well do that now, you may find the problem (leak) while doing it.

You haven't bled it yet. So why would you need to bleed it AGAIN!

got all belts replaced about two months ago and the mechanic degreasd and cleaned up the whole engine and bay for me,cant see any fluid anywhere, its all clean so no leaks in the engine bay at all
lyonruge,
Oct 20, 9:01pm
when you replaced the pads, how did you get the pistons back! did you open a bleeder or just push the fluid back through the system! does it have abs!
lyonruge,

, the leak may be at a wheel, or a flexi hose, not in the engine bay

lyonruge,

forrest39,
Oct 20, 9:05pm

lyonruge,
Oct 20, 9:07pm

BLEED THE SYSTEM!

You're going to need to bleed it. But you should also investigate where the fluid has gone. It may simply be that the level was never correct. Or it could be leaking.
