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.
1 Normal blood pressure is below 120/80 mm Hg. 2  Prehypertension blood pressure (120 to 139 systolic or 80 to 89 diastolic) indicates an increased risk for developing high blood pressure. 3  High blood pressure (hypertension) is greater than or equal to 140 mm Hg (systolic) or greater than or equal to 90 mm Hg (diastolic).octors may also categorize hypertension based on what portion of the blood pressure reading is abnormal: 1  Isolated systolic hypertension occurs when systolic pressure is high (over 139 mm Hg) but diastolic pressure is normal (under 90 mm Hg).
