Loss of brake fluid

#1
Hi All
I've been slowly losing brae fluid over the last 2 weeks. Got sometime tomorrow to investigate. Any common prblems I should look for? It's a P6B auto. The brake servo was replaced about a year ago by Colin Gould.

Any hints gratefully received

Thanks

First thing to look for would be drips underneath :)

I had an internal leak in the servo, which didn't affect the braking performance, but did do something else. When I let him tick-over for a little while, trying to pull out from a junction for instance, the initial acceleration would produce enough white smoke to obliterate anything behind me.

When my master had a leak it did not go into the footwell as normally happens. Somehow the dust cap kept the oil from leaking inside the car so the oil ended up leaking inside the cavity and dripped onto the suspension rubbers. I was under the impression that either the reservoir leaked or the pipe between the reservoir and the brake pipe leaked so replaced those first. Now the suspension rubbers need replacing as they have gone soft and spongy.

this seems to be exactly what has happened in my case. footwell is dry but leak of brake fluid on to suspension components is very much in evidence. have ordered refurb kit for master cylinder.

I wouldn't bother to reseal it 9 out of 10 master cylinder bores will be badly corroded.
By a new one ( not new old stock as many are at least 30 years old )
It's a single line system with no safety features so don't scrimp on anything brake related.
