Brake fluid leak (clutch not break)

[Tobias13]

Morn all,

So I noticed a small amount of fluid under the pedals this morn and have traced it to the cylinder behind the pedal!! There appears to be a pot with a face plate and gasket, I tighten the bolt but wasn't really loose!!

So I referred to the Haynes and my setup appears to be completely different to that illustrated!! Haynes suggests the cylinder is directly under the reservoir in the dash, I have a hose from the reservoir down to behind the pedals, pics below!!

Any advice would be greatly appreciated on possible repair etc!!

That's the master clutch cylinder - doesn't necessarily mean the leak starts there

[Smcknighty]

What year is the van? I'm envious of the shiny looking speedo and the high tech brake fluid level sensor!

[Smcknighty]

If it was me I'd be keeping an eye on fluid levels and also checking back for more leaks after you tightened the coupling. Clean everything off so that you can see where the leak comes from. Has it had any recent clutch or brake work - even a fluid change?

[Tobias13]

It's an 85'!!

I cleaned it all up last week and checked this morn and there is no dripping on the foot well but the cylinder and pot are wet as is its seeping out!!

Didn't realise it was the clutch, does it share the reservoir with the brakes?

A few months ago my brakes were reported to be imbalanced during the mot so had them done! The mechanic said he just cleaned and the calipers etc and all was sorted!!

The reservior shows plenty of fluid, so I guess the question now is 'is it safe to drive'?

As for repair the manual show no reference to the pot just above the cylinder so stumped on a repair!!!

[Smcknighty]

Clutch shares reservoir with the brakes. Cylinder and pot are wet?? By pot do you mean the fluid reservoir??

[Tobias13]

No not the fluid reservoir in the dash, in photo one there is a square type pot just intron of and above the cylinder!!

K I've not replaced the master cylinder yet so it's hard for me to help you. This is a master cyclinder https://www.brickwerks.co.uk/index.php/ ... l?___SID=U" onclick="window.open(this.href);return false;

Is the leak coming out of this? If so bob's your uncle! If it's coming from further above then maybe the brake servo is dripping fluid down

[Smcknighty]

Just thought I'd look out of curiosity and found this https://m.youtube.com/watch?v=StawBx6oXNA" onclick="window.open(this.href);return false; this guy's videos are normally very good

[Tobias13]

Thanks mate, much appreciated!!

Yes it is the same as brickworks but I have a small pot type thing attached to it, the video and web does not show this!!

Tbh it's hard to tell what's going on as I can't really see, I think it is wet up top by the rubber gator thing!!

[Smcknighty]

No need to see, just touch, mine is bone dry everywhere. If it's wet around the rubber gator it sounds like the master to me

[Tobias13]

Yea def leaking!!

Vid is good so thanks!!!

Guess it's a new cylinder then!!!

Can it be driven with that small weep, really need to use it this week??

[Smcknighty]

Your guess is as good as mine...! Good luck

Are you sure that the 'fixer' didn't retract the brake pistons without removing fluid from the reservoir first - this may well be the case. ( check the obvious first, it may not be doom and gloom)

[Tobias13]

No not sure at all!!

The reservoir does seem over filled now you mention it!! So where would it be coming from in that case!!

It's so restricted in there it's hard to tell!!

Bit more investigation I think!!
