Mk3 Scenic's floor-sponging brake pedal

[DJWilliams77]

It came today, and it brakes much better and turns on easily.
Braking has never been great or what you'd expect, and there was no advisory for braking, so I'm not sure how it passed. However, with this new calliper, it's much better. We've had the car for six months with a new mot, so I'm still not sure.
Even though they aren't in great shape, I will soon have new discs and pads.
Hopefully this time it works the first time around, because I would have wasted a lot of time and money trying different things to see if it worked. Your assistance has been invaluable.
Best regards

Do not ingest brake fluid; it is poisonous. If it gets on your skin, wash it off immediately. Prior to driving, ensure that the system has been adequately bled and that the pedal remains firm, as the calliper was leaking.

In order to try to identify the fluid, many traditional mechanics will feel or taste it. I know it's wrong, but it has helped me save a tonne of time on planes and cars before

Brake fluid, which I was using in the 1990s, is completely ineffective.

Following the car's repair, I decided to replace the brake pads and discs all over. Everything was going swimmingly until I encountered a calliper that wouldn't wind back with the motor or when manually pushed back with the motor removed. I promptly purchased a replacement and will be patiently waiting for its arrival tomorrow.
After that, I'll retrieve the previous model and disassemble it to determine its issue.
