Default Need help with hydro booster or master cylinder

Hello, can anyone help me, so basically I replaced all the calipers and flushed all the brake fluid… why I’m having now and before is, when I press the brake pedal nothing happens 3/4 of the way and then the rest of Pedal is hard, and when I release its slow to return, so I don’t know if I need to replace the master cylinder or hydro booster

Did you flush both the front and rear brakes?

Yes, before I forgot to mention I changed the abs module, and then flushed all the brakes 3 times in a row good steady stream coming out and no bubbles, so it comes down to these things
- either change the master cylinder
​​​​​​- change the hydro booster
- don’t k ow if I need to flush the abs module since I’m having good flow and no bubbles

Have you resolved it? Have you resolved it? if not then, replaced the callipers and flushed the brake fluid, if you're still experiencing issues with the brake pedal. If still not fixed then you should get p[rofessional help. Although I am looking for a booster cylinder have some money problems, Recently I accidentally visited an online casino reviews site https://casinosanalyzer.com/casino-b...egascasino.com which shares some grande vegas casino promo codes and get all the benefits and earn more money. And about your problem yes, it's possible that there could be an issue with either the master cylinder or the hydro booster.

No I haven’t solved it, also I changed out the abs module, don’t know if that affects anything bc I flushed the brake fluid through the calipers and everything seemed good, just slow brake pedal return

Have a look at the brake pedal pivot. Make sure that feller isn't binding.

I did and doesn’t look like it’s hiding or off everything is normal and no leaks anywhere

Ok, so, that ain't it....

Brake or ABS lights on? Does it feel like you are getting any assist from the hydraboost? Might not be a bad idea to separate the master cylinder from the booster, and see if you have fluid in there... (leaking from one, or the other....)
