reverse bleed

[laney]

Hi all has anyone done or know how a reverse bleed is done on the hydrochloric clutch system of the td5 disco will it damage any thing doing this.

[DazzaTD5]

To answer your question (rather than asking why??)....

No, I cant see it damaging anything, the flow does go in both directions.
I'd suggest its harder to do though.

But be careful around acid.

The reason why I ask is I am doing this job by myself and figured reverse flush would be easier as air naturally wants to go up .

[sierrafery]

Connect a transparent hose to the clutch slave cylinder long enough to reach the front brake nipple, open the slave cylinder's bleeder, let the hose fill with fluid by gravity or fill it with a syringe, connect it to the brake bleeder, open that too, top up the reservoir and pump the brake 15 - 20 times, tighen both bleeders... clutch reverse bleed done

I'm confused!

never flushed a hydraulic clutch setup(mine have all been cabled manuals). but have flushed brakes before.

With a flush, the implied method is that you force fluid down.

I'd have thought that a 'reverse flush' would be one where the fluid is forced upwards .. ie. from slave cyl to hydraulic reservoir?

What happens to all that excess fluid in the reservoir?

[sierrafery]

No excess fluid cos the brakes and the clutch are sharing the same reservoir and by pumping the brake the fluid goes down through the brake line and climbs back through the clutch's pipework, it simply circulates around and the air goes out through the reservoir

Didn't know that the clutch and brake share the same reservoir.

That is such a smart idea.

Nice work[smilebigeye] , especially if the fluid is reasonably new

[dinosaur]

The only way to bleed a mercedes clutch is reverse. I got a large syringe from a chemist, and plastic tubing, easy to attach to bleed nipple on slave cylinder, loosen and push slowly up. be careful about overflow from the master cylinder. its actually easier to do when youre on your own.

Thanks all for your help.

Hey Daz,,,
If I were to gravity bleed, does it still matter where I start?

[sierrafery]

If you want to renew the fluid by gravity open the nipples one by one in the correct order just dont let the tank get empty
