Whip the drums and see if its collecting there, check all the lines to see if they look damp. And if you have a servo, check for white smoke out the exhaust, then check the vacuum tube for fluid.

drums i took of yesterday and they were fine just full of dust :) all the lines seem dry (bit oily and muddy i need to clean them one day) but no break fluid i haven't seen any white smoke and there isn't any when it starts up and where is the vaccum tube and how do i check?

The vacuum tube will go from the carb/ manifold to the servo. Its usually a thin tube made of hard plastic with fatter rubber ends on. If the diaphragm in the servo breaks down, brake fluid can be sucked into the engine and burned.

check your carpets, if the master is leaking inside the car.

Master cylinder!! We had the same issue on the blue one... Checked everything (rear cylinders, all fexi's, servo and pipes...) Changed the master cylinder and all has been well... It was easy too, just a bugger to bleed the brakes!


I advise you to buy a new Master Cylinder...

How quickly does it go down, and by how much? If its small and slow I'd clean the brake lines just to make sure it's not a slight leak there, you did say they were oily!

[Kieranlee999]

It varies from the max mark to min mark it took about 2 - 3 weeks for it to go down but i topped it up again to max and its not gone down at allbover the past week.

If you replace a master cylinder, try to bench bleed it before fitting. Works on old mustangs

take the rear drums off and inspect the brake cylinders. lift the rubber gaitors to check for leaking fluid.

I'd be seconding the possibility of the MC leaking into the Servo. You might not be getting any white smoke yet because it hasn't full up the servo enough yet to reach the vac pipes. It happened me before.

Yep, I'll second this.  I had a loss of fluid on my Mini and kept topping it up until I found the Servo to be 1/4 full of the stuff.
