Flushing Brakes

[chadwicke619]

So, just some thoughts from someone who tracks their CTR and does their own brake work. First, I wouldn't use a pressure bleeder if I were you - not only does it not really make the job any easier, but I find that you tend to use way more brake fluid than is necessary. When you're using something expensive (I use Project Mu G-Four 335 which is pretty pricey), I’d rather not waste it. The stuff I use also changes color as it absorbs water, so you can visually identify when it needs changing. Anyway, just buy yourself a bleeder bottle with a backflow valve and that’s all you need - I pretty much never use my pressure bleeder and just use the little bleeder bottle. The pressure bleeder essentially just saves you from having to push the brake. I’ll do a quick bleed every couple of track days, just to keep my pedal at max firmness, and it takes like 10-20 minutes to do the whole car, including the rebleed on the rears.

Same. Start with front driver side. Put it all back together when done. Cycle ebrake five times then bleed the rears again.

I've seen this vid on youtube.

there is also this one if you are using a pressure bleeder -

Remember when finding a hazardous waste collection can be a PITA. I went to four diff places and they did not accept brake fluid. I ended up giving my fluid to a shop and tipped them.

I almost think paying a shop to do future flushes is more worth it.

Dumb question. My car only has 3500 miles. How can I tell when old fluid has fully flushed out and new fluid is only in lines if both are “clear”? Can I add a coloring of some sort? Missing the ATE blue days. Lol

My car has around the same miles like yours, to be honest, there wasn’t much of a color change and also the reservoir is not completely clear. The clutch uses the same fluid so if you don’t flush that, it will get mixed. I could be wrong…

So I have to bleed the clutch too?!?

 

[S4one]

I didn’t

Found the video. Easy enough.

just gotta flush more fluid through. I flushed with 500 miles and was impossible to see so I just did 1.5 litters to make sure. Also common sense to flush more on the rear brakes than on the fronts since they are further apart.

Planned on replacing the brake lines then using autozone dot 4 to bleed the new lines and then flush all that out with Castrol SRF. Don’t want to waste that liquid gold.

That sounds like a lot more work and time and to me time is money. Since srf only comes in 1L you have to buy 2 bottles anyways so Id just do the flush with it since you have 2 L anyways. But yes its def liquid gold, I just get it from fcp euro and just return it each year and have free brake fluid changes for life

Found this dye some have used to detect leaks in their brake lines. I’ll call them tomorrow to see what they say.

most of the other bottles are 500 mL. 1 Bottle of SRF is more than enough.

from what I had read to completely flush the system and make sure you don’t have old flush you need more than 1 bottle. Maybe not true and for future bleeds I will just use a bottle only but for the first flush I wanted to make sure the old crappy stuff is gone
