Title: Bleeding the front brakes
Post by: ChrisPy on May 10, 2011, 06:25:29 PM
Hey there, my new-to-me 2008 S4RS has a slightly spongy feel on the front stopper, so I want to try bleeding it.  I see it has a bleed screw on the master cylinder as well as on the calipers - which I've never seen before.

What order should I bleed in  - closest to furthest or t'other way round?

Cheers and many thanks for any advice
Chris

Always...

Caliper-caliper, always start furthest out...  Not sure if the bleeder on the master plays the same as the others though, or if I'd even monkey with it - Don't want to get through bleeding the whole system, then introduce air by accident right at the top, ya know?

Gents...

Thank you. I'll do the calipers and stop there if it feels good enough.

They added the bleeder at the master to eliminate the possibility of air trapping up high.

Don't be afraid to use it.

+1.

On my setup, it's the only bleeder I've got. It took a while, but I was able to bleed the whole front brake setup using just the master cylinder bleeder.

But if you've got bleeders on the calipers, by all means, use them.

Wow!  I never actually looked closely, I just assumed that they are there.  I'll look tonight....

I swapped out for fancy-schmancy Fren Tubo brake lines and they came with anodized banjo bolts.

I could have reused the stock banjos with the bleeder built into them, but I'm vain.
