self adjusting brakes still use more fluid than a caliper---
Comprehension issues, let me be clearer if I can.
As PADS WEAR the PISTON inside the CALIPER moves further out of the BORE. the MASTER CYLINDER has to supply the additional fluid to fill that extra space in the bore. This is the "make up fluid".
No one said anything about the amount of fluid required during braking, other than you.
The reason self adjusting brakes do not require nearly as much make up fluid as calipers is because the self adjusters keep the shoe to drum distance the same over the wear life of the shoes. Therefore the wheel cylinders do not have to travel farther due to shoe wear, UNLIKE A CALIPER. Non-self adjusting brakes have the same issues discs have in regards to makeup fluid, unless they are regularly adjusted manually.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
