CP8350 (Sprint) Caliper Volume/Capacity
 

When it comes time to replacing brake fluid how much should I run through the caliper to insure that all the fluid has been replaced? Plus a little in the line as well.
Also, can anyone recommend a (smallish) pressure/vacuum bleeder?

Ta.

I've used a Vacula before, but now I just do the old-school bleed or gravity bleed if I have time to spare.

To flush the system I think I went through about 2 bottles last time (flushed entire system) but it may have been 3. That's 500ML bottles.

Motive Products pressure bleeder. It's not a vacuum system, but builds positive pressure to push fluid out. Fill the pump with your favorite fluid and it becomes a one man job. If the old fluid's dirty it should be reasonably easy to tell when there's fully fresh fluid throughout the system. Personally, I liked alternating between ATE Type 200 (amber) and ATE Super Blue (...blue obviously) so that you could really tell when the old fluid was out.

I've done that for years with the ATE fluid. Still do so with the race car. BRZ boiled it though so I switched :)

We had no issue flushing out the whole system, front and rear, with 1 500mL bottle of fluid, but we've also bled brakes... way too many times. If you want to play it safe, use 2 500mL bottles or 1 1L bottle (depending on the fluid of your choice).

If you have a buddy (or wife, or gf, or kid) that can pump the pedal for you, it's a great way to save some coin.

Oh yeah I had to flush mine twice, switched back to OEM lines for the SS line recall :)

Recall? Got a link or anything?

I had the Griots Vacuum bleeder and thought it was a very good piece but it never quite did the job well enough. One might say, "it didn't suck enough." What I do like vacuum bleeders for (if you have the right adapters) is bench bleeding a new M/C. As far as replacing fluid, depending on how old or heated it was, you may be able to see the color difference. But I'd say about 1 cup is plenty if the fluid in the rest of the system is the type of fluid you're planning on running: aka; you're not completely changing fluids.

If I have nobody to help me then I use speed bleeders, otherwise I just stick the g/f in the driver seat and have her push on the pedal.

BTW: the stainless steel speed bleeders are worth the $$ but if you bleed your brakes a lot(like I do: 20 times a year) then you need to remove the bleeder occasionally, clean off the threads and bake new sealant on it and it will work perfectly again. So the trick is keep good ones as spares ready to go and just freshen up the ones coming out and put them back in rotation.

Initial batch of Spiegler lines. Essex replaced them all. I installed mine and then got the email the next morning :)
