I initially did single man pump and bleed and pedal was still spongy to me do don't have that same feeling compared to Cadillac ATS with same setup

Did Gravity bleed firmness of pedal improved but not to my liking yet
I notice very very small bubbles still coming but no large ones let it bleed for like 8 mins or so still had very very small bubbles so I called it a day

I plan on doing 2 man bleed again see if that improve more

And recommendations on firming pedal

 

Your setup is a bit different than mine, Ls1 front, stock discs rear. Anytime I open the system at the master or prop valve it seems to take more to get all the air out. The master can be difficult. I think a combination of pumping and gravity will help. And it sounds like you have 4+ piston calipers since you are referencing inners and outers so that may compound the problem. There is always the possibility when changing to non-factory (for that vehicle) calipers that the bleeder port isn't at the very top of the caliper. Probably not an issue but something to check. A V-8 Vega I had one time had 2 left calipers so I had to remove the right side and turn it upside down to bleed it lol. Anyway, the pads contacting the rotors can leave some sponginess in the pedal until they are well seated. My pedal is pretty firm once it hits the friction point but can still be mashed further as in a panic stop. I don't know you will get it brick hard but it shouldn't be vague either.

 

I'd try it with a friend. The single-man set up is good in a pinch but in my experience having help works better.

I've also had cases where it took WAY more tries than expected to bleed a system.

 

I had a problem with mine to so here's what I did I bleed the master on the bench an then started in the back ps side rear ds rear ps front ds front an backs were good the fronts nothing so this is what I did to get a good pedal I disc. the lines on the master an bleed it again on the car then I got every bubble out so next pump the pedal an do the backs if they are good go to fronts an pump the pedal not all the way down about 1/2 way an hold it you wont have any bubbles an you will have a good pedal you can also gravity feed them I did that to an got the same good pedal but this takes longer to do these are manual brakes dics to disc I hope this all helps.

 

Caliper are installed right lol but it is honest

I'm bleed again see what happens my hanks for the info

 

Bench bleed the master whenever possible. They are difficult to get all the air out of probably because of the angle they are mounted. Bubbles have a hard time going down hill.

 

Yea I will try to do that I'm running 4th gen master cylinder its a brand new from dealer
