brake reservoir tubing

[Bill]

It's great that your looking for and finding alternatives to the problem. But is anyone holding the person/company that sold this stuff to you accountable?  It seems like replacements should be coming from that source.

Greetings.  I seem to have brake fluid disappearing from my master cylinder resevoir!  So, while I intend to check each wheel cylinder for leaks, I think it best to start by replacing the tubing from the resevoir to the master cylinder as I find some fluid on the underside of the master cylinder.
2 questions:  I see Bremo has 9 mm tubing http://www.oppracing.com/product_displa ... voirs-9mm/  for 8 bucks a foot.  Would one foot be sufficient?
Is there more readily available tubing (auto supplies stores, i.e. Napa and the like)?
regarding removal of resevior tubing, will this require bleeding the entire system?
(I think I will anyway to ensure that new fluid DOT5 is throughout).
Thanks for any info.

I have the same problem. All the fluid"disappears into my power brake unit! Needs an overhaul. I'll get to it-someday.

Interestingly, the fluid in my Coupe's master cylinder reservoir also has gone down a bit in the few weeks since I flushed and bled the brake system. The pedal is firm and doesn't sink when I hold it down, so I don't suspect a leak in the calipers, wheel cylinders, etc.
So if there is an issue with the brake booster, what happens to the fluid from the master cylinder? Does it eventually get sucked into the vacuum line and intake manifold?

Make sure it's not leaking back into the car where the master enters the firewall.  It could easily be leaking there where the seal in inside it and u might not know because your carpet soaks it up.

Good point, Eric -- I'll check that.
I have noted that the engine revs go up when I press the brake pedal -- particularly so shortly after a cold start in which the choke is pulled out a bit. This behavior has led me to wonder whether there's an issue with the brake booster.

Miles once told me about pressing the brakes and the effect it has on the RPMs and what that means to the booster but ofcourse I forgot.
Maybe he'll chime in

I had the same problem, I couldnt figure out where my brake fluid was going. I finally figured out I had the same problem as Bob with it staying in my brake booster after I started having fluid fill the breather hose from the top of the cylinder head (thank goodness for the inline check valve otherwise my engine would have been filled with Dot3) so I romoved the breather hose and capped the inlet/outlet. Then came the final final blow, we were at a local car show and cruise night and after going up and down the strip I found I had no brakes. I found brake fluid had overflowed from the Breather vent on top of my brake booster and had completely drained my reservoir.  I limped home and removed the brake booster and just bent the tube to the master, refilled the system and bled it and I haven't lost a drop of fluid since. My brakes work better now that its a closed system again and the brake booster is sitting on the floor of my garage awaiting its fait whether to be rebuilt or sold. So be careful about your fluid disapearing into your booster it may eventually come to a messy end.

i will check again more closely, but do not think it is leaking at that point.�

i have not considered this scenario. in any case, i think replacing the hose from reservoir to MC is worthwhile once i get the correct type of hose.� then a flush of the system is in order.���
when you bled the system, did you start with the rear tire on the driver side?
