Bleeding the clutch


Recommended Posts

I'm going to bleed my brakes and clutch and just wondered if the procedure is exactly the same for the GT3 (and specifically the Mk1) as Loren's instructions? Is the clutch bleed valve in the same location as with a normal 996?

Loren, I bled the brakes, however someone on another forum questioned performing this yourself as they claim:

A small note of caution, if you're doing this as the 2 yearly brake fluid change and you have ABS you will not be removing the fluid from the ABS unit. It's effectively on a "dead leg" - regardless of whether you use a vacuum or pressuer system for bleeding, the old fluid will stay in the ABS unit.

The ABS pump needs to be "cycled" during the bleeding process to remove the old fluid - dealer job to do properly!

Is this correct?

If you are using the same type brake fluid then I disagree. In a perfect world there would be a way to remove all the dirty oil from your engine too - but you can't without flushing. If you are changing the type of brake fluid from the original ethylene glycol type (which Porsche recommends) to say a silicone brake fluid then - yes, all traces of the non compatible type should be flushed /removed. IMHO if you change your brake fluid regularly you are doing the same as what you do with an oil change and making the concentration 99.9% new product. With flushing you might get to 99.99%.
