Damaged Replacement Caliper Causing Issues (01 ES300)
I purchased a replacement caliper from rock auto and installed it on the front right. There seemed to be a slight leak where the brake line attached to the caliper. I made sure the copper crushers were properly installed and tightened it more, this seemed to make the leak go away. I proceeded to bleed the right and then the front left. Took it for a test drive and everything seemed good although the brakes felt slightly spongy. Got back and noticed brake fluid all over the tire and driveway. The leak had come back and gotten 10x worse. It caused the fluid reservoir to run dry and seemingly introduce a boat load of air into the system. I examined the replacement caliper and saw a small cut right where the line seals to the caliper, this was definitely the culprit. I reattached the old caliper for the time being (no leak) and I’ve bled the entire brake system at the calipers twice now and the brake pedal still goes to the floor. Does anyone have any tips? I’m new to brake bleeding but have read a ton of things online so I feel like I have an idea.
Thanks

you could need to bleed the master cylinders. There are some tips to do it on YouTube. After that, once you get a little feel in the brakes, it could still be spongy. that could be air in the abs pump.
An old trick to get air out of the ABS pump is to drive the car on loose gravel and try to initiate a skid. Then repeat the bleeding process.
But first you want to get the master cylinder bled
