Message Some may remember my post about the great Brake Man service I got when I approached them with a soft brake pedal. The message is still available via search :)

Anyway, even after fully rebuilding my calipers and changing the master cylinder and 3-4 bleedings the pedal remained soft.

So, I decided I needed a brute force.

First, I did a few hard brakings trying to activate the ABS system (which was challenging somewhat - often it wouldn't engage probably due to the weak clamping).

Then I got me a long tube and started a new round of bleedings, piping the tube back into the master cylinder. And that helped. After about a minute or so of pumping, huge bubbles started coming out from the driver's rear side. And they kept coming and coming, ever so smaller.

Other sides didn't yield anything significant.

After that I got my pedal back. So, the moral here seems to be a long continuous bleeding session.

I just hope that I don't have a microscopic crack somewhere so the air can seep in and the reason at the root of the problem was a really hot day at the track.

Thanks for reading this far :)
