Clutch fluid leak : HELP Please

[Devans]

Last week I had my clutch slave replaced and since then I have noticed a substantial fluid leak that pools below my clutch pedal in the footwell. I'm assuming the leak is coming from the master cylinder.

Does anyone have any ideas or know what could be causing this leak? Easy fix? Could I need a new master cylinder as well??

Thanks!

Master cylinder has given up...

time to replace it...

or at least hone it and reseal it.

Not uncommon for the master cylinder to fail as that's now the weakest link after your new slave ;)

Is it possible to drive around on it and just top it up for a couple of weeks??

I recently done my slave cylinder. I have been topping up since it went in Uzbekistan back in May! ;) Held up fine towing too.

I had a leaking one, replaced it with a new factory one, it was knackered too! So then I got a s/s sleave put in and that has lasted for 10 years or there abouts (touch wood)

I'd really recommend getting your new master cylinder sleeved with stainless before you put it in. I had a bad run of 3-4 masters failing within 3-9 months of each other. It's been 18 months since i replaced it with a sleeved one and no issues so far. I'd also recommend taking notice of adjusting the pedal height to spec.

Fred Smith in Bayswater (VIC) keeps the st/st sleeved master cylinders in stock. You just have to re-use your original pushrod.
About $120 last time I got one.
Any decent brake place could get yours st/st sleeved, most have to send them away so you need to factor in the delay.

Several threads around on replacing with st/st sleeved.

You can do it without removing the pedal box, a bit fiddly and having an assistant helps.

I think it was Fred that told me :-
Defender - getting the sound deadening in & out around the pedals is too messy so remove the master cylinder.
Series - remove the pedal box.

Best of luck,

It's a bit late to tell you now , but you should replace them both at the one time , because whatever one you change the other will give up not long after , good luck . Jim .

Where can I find the specs for pedal height? I have looked through the owners manual but can't find it. Other forums have said 140mm. Is it the same for all defenders?

I have a 96 110.

Thanks for all the help guys.

It's 140 mm from memory from the bottom of the pedal to the floor with no mat in. Hope this helps

[Blknight.aus]

pooch measuring it from the floor

hold the pedal up with a bit of rope to the seat.

get in on top of the pedal tower and adjust the nuts,

when you can get a 1mm feeler gauge in and out between the washer on the nut thats closest to the MC in the pedal pivot nip up the top nut without turning the shaft or the bottom nut.

I found using dot3 instead of dot4 fluid helped with prolonging the life of my master cylinder as well as annually changing fluid. My new spare ( I have a habit of keeping one in the shed from previous experiance) cylinder actually has this written on outside of packaging - I believe toyota had an issue with this and wouldn't cover master cylinders under warranty if using dot4
