Master cylinder problem has me stumped

There's no good reason to clamp a brake hose. Just remove it from the wheel cylinder and plug the open end. That's how I was taught, anyway.

 

I'm surprised this thread is still open with all the drama.

 

I have never been able to clamp a brake hose tight enough to hold brake pressure without rendering it useless from destruction. Small squeeze from special brake hose pliers basically keeps gravity at bay and retains the fluid up hill. Those pliers give a light squeeze with controlled leverage and clamping no way will they hold pressure. They are not like clamping it with a visegrip.

Trouble shooting a brake system by clamping the hoses sound fantastically easy and logical if one can possibly ignore the reality and manufacturer warning against doing it.


You all do whatever makes you warm and fuzzy, makes you money, your insurance will cover and doesn't kill anybody.

Sometimes our teachers and mentors were wrong.
Doing anything wrong for a long time doesn't make it right.

 

True dat, I'm still learning stuff I should have know 40 years ago.
