Thread: master cylinder

Very very rarely will you see a master cylinder leak into the engine bay. 99.999% of the time it drips into the footwell.

If you have oil dripping down there then the oil seals have / are letting go and it will need fixing.

You have 3 options:
1. Get a repair kit and put new seals in your cylinder;
2. Get a 3rd party replacement cylinder
3. Get a genuine / OEM replacement

For me, having done all of the above over the years, I'd always go for an OEM unit now as all others fail prematurely. They are more expensive, but do a job once is now my thing. Older, wiser & can't be ar*ed doing it more than once if I don't have to!!

Of course, the fourth option is to keep topping it up with oil and practice changing gear without a clutch😄

Also, from memory the manual says you have to take the pedal box out, you don't - it will come out on its own, you may just swear a little more!

Thanks for the quick reply Jon, so you would think the ones on Ebay is not worth getting?

is there a brake booster in between the firewall and master cyl on the defender if so it may have filled the booster with fluid as well

If they are specifically noted as original equipment then yes, otherwise (for me anyway) no.

Suggest you have a word with someone like British motor Imports (Sydney) for OE local prices and perhaps also checkout Lrdirect.com (UK), they list all the different manufacturers and give prices, they also tell you if they are OE or pattern parts.

Having done it both ways, I recommend leaving the box in and just removing the cylinder. A ratchet spanner helps - 7/16" from memory.

Really Jon? Both my Tdi's have them.

If you do have one, and it's the master cylinder leaking, it's unlikely you'll have fluid in there. In my experience it just runs into the footwell.
