Pumping the brakes puts pressure in lines?
Hi ppl,
One of the pilots here on the east coast of Australia told me that if I pump the brakes after my gear is lowered on my Cessna 210 then this will put pressure in the brake lines making them more effective when needed.
I didn't get around to asking him but how exactly does this work.
I understand that there is a master cylinder and when the pilot steps on the brake pedals then hydraulic fluid is used to squeeze the brake pads of the brake disc of the wheel.
But how does a few pumps of the brake when on downwind put pressure in the lines and then how does it stay there - I always thought that the pressure being applied by the hydraulic system was pretty much instant and now prior pumping was required.
Can someone explain further - many thanks in advance.
