#1 Ideal spanner for rear brake bleeding?

Post by PhilBell » Thu Oct 06, 2016 12:47 pm

Has anyone discovered a make and model of spanner that makes it possible to move the rear brake bleed screws from closed to properly open in one movement?

In my experience, the only way to get the screw open enough for proper bleeding with regular spanners is to do it in two goes, making it impossible to shut it off again quickly enough before air bubbles travel back up the bleed tube to the screw.

What it appears to need is a slim ring spaner with a tightly curved shaft to allow more opening and closing of the screw before the spanner hits the edge of the slot in the IRS cage. I did consider buying a ratchet ring spanner, but the heads on them look too large to fit into the tight space on the E-type calliper.

I know that some of you favour remote bleed adaptors, but I think a suitable spanner would be a neater solution.

If you use an ezibleed (not the auto just the basic bottle and tube type )they have a one way valve on the end of the drain tube so you can take your time ....... you can also get bleed screw spanners...ring end with a slot cut in it.....just google both

Dear Phil,

I made one of these for my s3. Access will be different for your car, but a similar principle may apply.

Hi Phil,

I bought and install this remote bleed. Now it's very easy to bleed my rear brakes.

Think Steve means "visibleed" which is just a tube and one way valve. "Ezebleed" is the one that uses tyre pressure to supposedly force fluid through. It is the invention of the devil and just spills fluid all around the reservoir jars and does not work well in any case. However far better to get a remote bleed kit and then you can bleed the brakes without even removing tyres. I can do mine in five mins.

Yes...Vizibleed thats the one http://www.halfords.com/workshop-tools/ ... eeding-kit used it dozens of times on various cars....single handed bleeding so no assistant required no spills whatsoever as the bleed tube goes directly into a screwtop sealed container..... remote bleed does make things easier, i have them but you still need go bleed them into something....and the one way valve is simple and works

Just take the pipe off, then you won't have bubbles travelling back up it. But the bubbles aren't going to go back down into the cylinder in any case, provided the outlet is lower than the nipple.
