Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

What I notice is even for the rear with the longest line, you will get clean fluid out way before you hit 250mL, which is grossly overestimating the amount needed.

Does anyone know how much fluid you need to push through each caliper and the clutch slave to full replace the fluid?

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I'm getting ready to do some track days and want to replace my brake fluid before I go. My current fluid is clean, so it is almost impossible to tell when the "old" fluid is out and the new in. That is why I want to do it by measuring the amount. Last time I bleed and flushed my brake fluid, I found a post that specified how much fluid per caliper. I do remember it did add up to less than a liter. I can't find that thread again Does anyone know how much fluid you need to push through each caliper and the clutch slave to full replace the fluid?

POST 2Original post

125mL per bleeding nipple is full flush. Porsche specify 1L for a full flush.

POST 3 / ORIGINAL POSTEROriginal post

Quotes source post: 12628597

so that is 250ml per caliper would not the rears use more than the front as they have longer lines?

POST 4Original post

Quotes source post: 12628690

What I notice is even for the rear with the longest line, you will get clean fluid out way before you hit 250mL, which is grossly overestimating the amount needed. It's kinda like flushing your radiator. You always use more than the capacity.
