Hi all, I've had a wet drivers footwell for a few weeks and then yesterday after alot of stop start traffic my brake pedal has gone almost completely soft when depressed. I'm pretty much on the floor to get the van to stop.

I haven't changed the brake fluid, so let's assume it's knackered.

Is it likely to just be a leaking/failed master cylinder or should I be looking behind the wheels? It was in for MOT last week which was very thorough and nothing was picked up regarding the brakes.

Check your front brake pads for excessive wear, and re-top your brake fluid just behind the dash for a start.

Sorry I can't help with anything else this is my limit

When I had a soft pedal but no fluid loss on my kitcar, it was the master cylinder. After a few days it failed completely, which was rather alarming as it has single circuit brakes...

if you have a wet floor then surely this is brake fluid leaking from master cylinde, check where it's coming from, easy to look up under the dash, maybe a switch leaking.
Don't drive it.

Thanks all!

I've had a snoop and it's coming out of the top of the cylinder behind the pedals. The break pedal is simply pumping fluid out.

Check my post regarding brake fade in Wheels and Tyres 2 days ago. That might help too.

I haven't taken a picture yet, but it's the clutch master cylinder that's pissing fluid. Am I right in thinking that within the cab area it's all one system? So if the clutch master cylinder is leaking then pressure from the brake pedal would be gone? I'm not having any problems selecting gears though, although I rarely get beyond second.

It's looking like a bigger job, and although I generally undertake all work myself I think I'm going to get a garage onto this and to just sort the whole braking system. I bought the van 5 years ago and put it to work right away. I use the van daily, and do service regularly but have always given the brakes a miss. This, is foolish so off to the professionals he goes
