How it's done: 1  Inspect rear wheel cylinders for leakage. 2  Inspect rear brake shoes and hardware. 3  Replace wheel cylinders if found faulty. 4  Adjust rear brakes. 5  Lube backing plate. 6  Make sure axle seals are not leaking into brake drums. 7  Bleed entire brake system. 8  Perform a brake inspection, including test drive.
The bottom number, called the diastolic pressure, is the measurement as the heart relaxes between beats. Normal blood pressure is a systolic pressure of less than 120 millimeters of mercury (mm Hg) and a diastolic pressure of less than 80 mm Hg, or 120/80 mm Hg, according to the American Heart Association (AHA).Having a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension.A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.aving a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension. A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.
As defined by the American Heart Association, the top number, or systolic blood pressure is normally less than 120 (mm Hg, millimeters of mercury), and the bottom number, the diastolic blood pressure is normally less than 80 (mm Hg). In other words, 118/78 is considered normal, but 120/80 is not. Prehypertension is defined as a systolic pressure of 120-139 or a diastolic pressure of 80-89. A systolic of 140 or greater, or a diastolic blood pressure of 90 or greater is defined as hypertension, or high blood pressure. A hypertensive crisis is a diastolic pressure of greater than 110 or a systolic pressure of greater than 180; this requires emergency attention.
