I'm getting ready to bleed the brakes and I've seen reference to this drain tube and needing to be clamped off in a number of DIY/searches here.

Can somebody show me where/what this is?

I will be using my Motiv power bleeder for what it's worth.

Thanks.

IF you have one it comes out of the rear facing end of the brake reservoir. Late build cars don't have it, and given your signature, yours probably doesn't .

Thank you for this easy answer!

Be sure to check though because if you have the vent tube you'll need to clamp it off or brake fluid will spray out when you pressurize the resevoir.

I couldn't find anything that resembles this description which is why I made this thread. I think I'm in the clear unless you see a new thread later this week that reads "I'm covered in brake fluid."

Actually, the old style set-up would allow the excess fluid to **** out behind the driver's side front wheel.

-I just stumbled on this tread...

I have the drain tube (1971) where do you clamp this? and won't it just pop off the slip on fitting of the reservoir?

(I have a useless power bleeder, since it forced the fluid out).

can any reservoir be substituted?


TIA!

Good to know where the pissing may occur.

Just clamp the rubber tube with a hemostat or locking pliers. Check that the fitting on the resevoir is tight but if you're using enough pressure to blow that off then you're using too much pressure.

Is the black tube circled in red the drain tube referred to in the original post?

ok, mine is totally different.

my overflow is at the top, and very thin OD. but I'll give it a try...

MrBonus

I'm retarded. A drain tube would be at the top, not at the bottom. I imagine I have the newer design.

If someone would confirm, I'd appreciate it. Everything about these cars are quirky so I want to make sure my standard procedure for power bleeding isn't interrupted by some random tube that I'm unfamiliar with.

I'm assuming the overflow would look something like this, correct?

Here's the older style reservoir drain tube. It goes around the reservoir and you clamp it where the left arrow is.
If you have the older one, you need to clamp it, if you don't, you will have fluid pissing out in the front wheel well as already explained. Ask me how I know...

You have a newer version so no need to clamp anything.

Thank you, Flying Finn!

I know this is cross posted in the 993 page....but...

I just learned this one the hard way. Was bleeding my new clutch slave before installing the engine and, yes fluid starts draining out just behind the wheel well. Any painted surfaces in the wheel well I need to worry about? I cleaned everything I could find on the exterior.

Just so happened this plastic bin lid was sitting on a box below it all. Pulled the box out of the way and let it drain.






You will know this is about to happen when you start trying to pressure up your pressure bleeder and it's taking a while....

Here is the solution.... clamp the drain line with a small set of vise-grips, etc.
