LBC leaks

[TonyPanchot]

ok I need some feed back please

I have replaced all the hydraulic components of my clutch system and using DOT 5

the car (TR 250)sat for 2 months and the system was completely depleted of fluid.

why does this happen ?

It would seem that the lack of movement would preserve levels

thanks for any info

Well it would seem that there is a leak

More seriously, were these new / rebuilt components? Is there a puddle somewhere?

If there is no puddle, I would guess that you may have had air in the system which worked its way out. The reserve for the clutch is rather small so even a fairly small bubble slowly moving out could cause the level in the reserve to go down quite allot.

Hi Tony,

I would agree that you should see fluid somewhere if it was fully depleted - either on the garage floor from the slave or in the car if the master and that should help identify the "bad" component.

I haven't had any issues like this and I posted recently that my TR4A's clutch where I rebuilt original components and used DOT5 amazingly still works after sitting around 18 years (and 7 years of use before that). The brake system didn't fare as well and has leaked fluid somewhere (my guess is the rear wheel cylinders since I didn't see any evidence in the car).

For it to leak after sitting 2 months I would think there has to be a cylinder or seal with something wrong with it.

Dare I say this, but you might check under the carpet under the drivers footwell. If the master leaked, it could have gotten behind the carpet. If it did, it will destroy the paint on the floorboards.
I hope I am wrong!

Elliot,

He indicated DOT5 which should not destroy the paint.

Scott- Thanks for pointing that out... I did not know that!

Definitely one of the main reasons to use DOT5 silicone brake fluid after you have spent all the time and money restoring your car. Note that you need DOT5 and not DOT5.1 as DOT 5.1 is not silicone and will eat paint.

Here's a page that explains the different grades with advantages and disadvantages.
